The difference between UV glue dispensing and AB glue dripping: Detailed explanations of applicable processes for various accessories Customers engaged in accessory processing, handmade accessories, and accessory products all know that dispensing glue and dripping glue are the most commonly used techniques. The mainstream glues on the market basically use UV glue dispensing and AB glue dripping. Many customers often make mistakes when choosing glue, resulting in problems such as blistering, whitening, yellowing, overflow, poor curing, poor quality and texture, and high defective rate of accessories. To achieve good accessory appearance and increase production, choosing the right glue and process is crucial.  Among WELDO's customer base, customers who make jewelry have largely abandoned the traditional manual dispensing method. The visual dispensing machine has become a standard automated equipment in the industry. It uses intelligent visual positioning and computer program control for dispensing, ensuring precise and stable dispensing. It can perfectly adapt to the different properties of UV glue and AB glue.  The main differences between UV glue and AB glue lie in the aspects of curing speed, operation difficulty, final product effect, and applicable scenarios. When used with a visual dispensing machine, the corresponding production mode is completely different. 1. UV Glue UV glue is a one-component adhesive that does not require manual mixing or proportioning. The operation is extremely simple. It only dries and solidifies under the irradiation of ultraviolet light. With a regular UV lamp, it can become fully hardened within 2 to 5 minutes. Even strong sunlight on a sunny day can initially solidify it. The advantages are obvious: high transparency, thin adhesive layer, quick drying, almost no shrinkage, resulting in clean and transparent accessories without any obvious glue marks. When used with our UV Glue Dispensing Machine, the effect is even better: the equipment can precisely target the tiny positions of the accessories for micro-dosing of glue, without sagging, overflow, or accumulation of glue. No heating is required, and there is no need for long waiting times. It is highly suitable for large-scale and rapid production. Disadvantages: It is not resistant to long-term exposure to wind and sunlight, and is not suitable for thick adhesive layers or large-scale pouring.  2. AB Glue AB glue is a two-component epoxy resin glue. It must be mixed and stirred evenly in the proper proportion (usually 3:1) before it can be used. It undergoes chemical reaction when the A agent and B agent are mixed together to achieve curing. The curing process is relatively slow. It takes about 6 hours in summer and 12-24 hours in winter for complete drying. The glue body of AB glue is thick, has strong shaping ability, good toughness after drying, resistant to dropping, wear-resistant, and does not age or turn yellow easily. It hardly deforms or shrinks when used for thick parts or three-dimensional parts. When paired with AB Glue Epoxy Dispensing Machine, it can automatically mix, stir, and eliminate bubbles, solving the common problem of uneven manual stirring and easy bubble formation. Although it dries slowly, it can be used for thick glue, large pieces, and three-dimensional shapes, making it the preferred choice for high-end customization and heavy industry jewelry.  Which kinds of jewelry can be made with UV glue and WELDO's Visual Dispensing Machine? Jewelry that is thin, small, transparent, delicate, and requires rapid mass production should use UV glue. By combining UV Glue Dispenser for precise dispensing, the finished products are exquisite, have a high yield rate, and are delivered quickly. A. Small and delicate jewelry Earrings, small earrings, thin ring bands, mini bracelet accessories, etc. are all suitable for UV glue. These types of jewelry have a small surface area and require high levels of flatness and transparency. The UV Resin Doming Machine precisely locates and dispenses the glue, ensuring uniform glue application without unevenness, and the curing process is fast, making it suitable for large-scale factory production. The finished products are clean and free of marks. B. Jewelry with diamonds, glued diamonds Necklaces, hair clips, brooches, headpieces, almost all of these are fixed with UV glue. The effect of UV glue on crystals, glass, and acrylic is very good. After drying, they are transparent and do not block the luster of the diamonds. By using the UV Glue Dispenser for intelligent positioning of the diamond positions and quantitative dispensing, there will be no overflow of glue covering the diamonds, and the glue will not be foggy and white. This significantly reduces defective products. C. Lightweight and Transparent Accessories Transparent small pendants, small phone accessories, nail art accessories, mini keychains, etc., are lightweight accessories that are suitable for multi-layer thin coating with UV glue. Hot melt Adhesive Dispensing Systems can layer and apply glue one by one, and after drying, it is clear and has distinct layers, avoiding common problems such as bubbles and uneven thickness in manual operations. D. Sealant Protection for Hardware Accessories Surface sealing, color fixation, and rust prevention for alloys, stainless steel, metal earrings, and bracelets. UV glue is the first choice. The Automated Glue Dispenser Machine can apply glue evenly, making the appearance of each hardware accessory uniform and the texture better. Because the curing speed is fast, it will not pick up dust during the drying process, and the glue layer is bright and transparent.  Which kinds of jewelry can be made with AB glue and WELDO's Visual Dispensing Machine? Thick, large, three-dimensional, heavy-duty, custom-made, and those requiring wear resistance and durability should use AB glue. The AB Glue Epoxy Dispensing Machine automatically mixes and dispenses the glue, resulting in a full and three-dimensional finished product that is not easily damaged. A. Three-dimensional resin jewelry Large resin pendants, three-dimensional ornaments, thick bracelet plates, flat decorative jewelry - these can only be made with AB glue. UV glue cannot handle thick layers, but AB glue can pour a 5-20mm thick layer at one time and will be fully three-dimensional, not collapsing or deforming after drying. The AB Glue Dispenser Machine evenly dispenses the glue, solving the problems of easy collapse, many bubbles, and uneven thickness when using thick glue manually. The finished product has higher stability. B. Customized dried flowers, specimens, jewelry Plant specimen pendants, dried flower inlay ornaments, gradient color jewelry, commemorative custom accessories - all of these can be made with AB glue. AB glue can be mixed with glitter, color pigments, and night light powder at will, providing a large color mixing space and resulting in jewelry with rich layers. The Dispensing Equipment can control the speed and trajectory of the glue dispensing, making the color mixing more uniform and avoiding local color differences, glue accumulation, and uneven surfaces.   ​C. Accessories for Hanging Items AB glue is suitable for thickening keychains, large-sized bag hanging decorations, outdoor decorative accessories, and accessories that are frequently used on a daily basis. AB glue has high toughness, is resistant to impact and pressure, and is resistant to aging. It is unlikely to crack, turn yellow, or lose adhesion over a long period of use. The AB Glue Epoxy Dispensing Machine can dispense glue in a quantitative and large-area manner, ensuring uniform thickness of the glue layer. The finished product is more durable.  Tips for Using WELDO Visual Dispensing Machine Whether it's UV glue or AB glue, using the correct machine parameters will significantly improve the final product quality and efficiency: 1. For UV glue process: Turn on the machine's precise micro-dispensing mode, activate the constant-temperature glue output, and ensure the stability of the glue flow; combine with UV curing lamps, and the dispensing and curing can be completed in one step, suitable for rapid batch production. 2. For AB glue process: When dripping glue over a large area, slow down the glue output speed, and during the curing process, keep it flat and stationary to avoid bubbling and deformation. 3. For mixed process for accessories: For some products with detailed point dispensing and local thick-layer shaping, you can directly switch to the visual dispensing machine program. With one piece of equipment, you can handle both processes, saving equipment costs.  In simple terms: For small and delicate parts, transparent parts, and those requiring quick production, UV glue should be chosen; For large, thick, and three-dimensional parts, AB glue should be selected for durability. Combined with the visual dispensing machine for automated operations, it can completely solve the problems of bubbles, overflow, uneven thickness, and low efficiency caused by manual dispensing, significantly improving the appearance quality and yield of jewelry products. It is highly suitable for long-term standardized production in jewelry factories, processing workshops, and manual workrooms.

The Complete Industrial Manufacturing Process for Fridge Magnets: How Visual Dispensing Machines Ensure High-Quality Finished Products Do you know how fridge magnets are made? Fridge magnets are popular gifts for home decoration, cultural promotion, tourism souvenirs, and corporate branding. How is a high-quality fridge magnet—featuring a crisp design, a clear texture, neat edges, and a strong magnetic hold—actually produced? From raw material selection, mold forming, and pattern printing to precision resin dispensing, magnet assembly, and quality inspection/packaging, a finished fridge magnet undergoes multiple standardized industrial processes. Among these steps, the visual dispensing machine is a critical piece of precision equipment that determines the magnet's visual appeal, durability, and yield rate; it resolves issues common to manual dispensing, such as uneven thickness, overflow, and air bubbles. WELDO takes you through the entire industrial manufacturing process of fridge magnets. 1. Product Design and Raw Material Preparation The first step in fridge magnet production is precise customer targeting and material selection, which determine the magnet's style, texture, and lifespan. Professional designers customize the specific patterns, appearance, and dimensions based on the intended use—such as cultural tourism souvenirs, creative merchandise, corporate gifts, or home decor. They distinguish between mainstream styles—including soft PVC, metal, acrylic, and epoxy resin—and generate standardized production blueprints. Key raw materials on the market include eco-friendly soft PVC, acrylic sheets, metal alloys, epoxy resin (A/B components), strong flexible magnetic sheets, waterproof inks, and curing agents. All materials must pass environmental safety tests to ensure they are odorless, wear-resistant, and non-yellowing, making them suitable for long-term home use. Epoxy resin serves as the core material for the protective surface layer, and the subsequent precision application of this resin onto the magnet's surface relies entirely on the visual dispensing machine. 2. Manufacturing the Base Depending on the material, refrigerator magnet bases fall into two categories: A. Acrylic and Metal Magnets These typically utilize cutting and stamping processes. Materials are precisely cut according to design drawings using CNC engraving, laser cutting, or metal stamping equipment. The process involves deburring, edge polishing, and dust removal. Subsequently, patterns are applied via standard or UV printing, followed by the application of a doming resin (epoxy) coating to finish the product. These magnets are formed through physical separation rather than high-temperature molding. Their 3D effect is achieved through printing or layering. As they do not require molding dies—only vector files—there are no mold-opening costs, making them ideal for same-day prototyping and small-batch production. B. Soft PVC Magnets These generally utilize an injection molding process. Eco-friendly PVC raw material is melted at high temperatures and injected into a custom, high-precision mold. After cooling and setting at a constant temperature, the piece is demolded to yield a base body with a defined outline. The edges are smooth and the shape is three-dimensional, allowing for complex designs such as cartoons, irregular shapes, and 3D relief patterns. These magnets are created using soft polymer molding and heat-cured resin application. They offer a strong 3D effect with distinct raised/recessed areas and multi-layered relief. This method requires mold creation (with associated costs) and a 5–7 day prototyping period, making it suitable for long-term, stable production orders. 3. Pattern Printing and Surface Pre-treatment The design is the core value of a fridge magnet, and high-quality printing is crucial for faithfully reproducing that design. Currently, the two most common methods for applying designs are screen printing and UV printing. Screen printing: Ideal for large-batch orders and multiple styles; offers high color saturation and strong adhesion. UV printing: Ideal for personalized customization and complex gradient patterns; delivers high-definition detail reproduction and natural color transitions. After printing, surface pre-treatment is required, involving steps such as dust and oil removal, static elimination, and pre-curing/drying. This not only ensures a clean, dry surface but also allows the resin applied by the visual dispensing machine to bond tightly to the magnet base, preventing issues like delamination, edge lifting, or air bubbles. 4. Automated Dispensing with Visual Guidance Resin dispensing is the most critical step in fridge magnet production, directly influencing both visual appeal and overall quality. The transparent epoxy resin layer protects against water, scratches, and yellowing while enhancing the pattern's brightness; however, the uniformity, thickness consistency, and flatness of the resin depend entirely on the dispensing equipment. WELDO’s AB glue dispenser utilizes CCD visual positioning and intelligent software algorithms to dispense resin onto magnets of various irregular shapes and inconsistent forms. This precision dispenser coordinates pneumatic cylinders and valve assemblies to accurately control the flow duration and volume of the epoxy resin. With frequent SKU changes and the need for rapid production switching and reliable delivery times, the AB glue epoxy dispensing machine offers a solution: it supports simultaneous dispensing for multiple product files, ensuring smooth order fulfillment. Traditional dispensing methods rely heavily on operator experience and are prone to issues such as uneven thickness, edge overflow, surface bubbles, and pattern misalignment. These methods typically yield a success rate of only around 80%, with productivity declining over time due to manual operation fatigue. Using WELDO’s epoxy doming machine boosts the product yield rate to over 98% and increases production efficiency by 30%, enabling standardized mass production. The stable epoxy coating process ensures that the surface of each fridge magnet is clear, smooth, and uniformly glossy, while significantly enhancing water and wear resistance; the finish remains durable over the long term, resisting yellowing and delamination. 5. Curing and Quality Inspection After precise dispensing with WELDO’s Enamel Dispensing Machine, the magnets undergo rapid UV curing followed by constant-temperature curing in our Hot Air Curing Oven. Typically, after hot-air curing, the epoxy resin requires a resting period of 4–8 hours in a dust-free, temperature-controlled environment to ensure complete curing and a clear, hard finish. Once the epoxy resin has fully cured, workers perform quality inspections. Some magnets require fine trimming—removing excess edge resin and polishing minor imperfections—to refine the contours and enhance the three-dimensional look of the product. Simultaneously, a secondary inspection is conducted to screen for issues such as bubbles, scratches, or surface irregularities on the resin coating, ensuring only high-quality fridge magnets proceed to the next stage. 6. Magnetic Assembly and Functional Testing Since the primary function of a fridge magnet is to serve as a decorative item that attaches magnetically, the assembly of the magnet component is crucial for ensuring practicality. Operators cut eco-friendly flexible magnetic sheets to fit the specific size of the fridge magnet. These are then affixed to the back using a specialized, high-strength adhesive and pressed firmly to ensure a flat, secure bond—free of air pockets and resistant to detachment. A dual-stage inspection follows assembly: A. Magnetic Strength Test: Ensures the magnet adheres firmly to refrigerators, whiteboards, or metal walls without easily falling off. B. Visual Quality Inspection: Checks pattern clarity, surface smoothness, edge neatness, and color consistency; defective products are discarded to ensure uniform quality. 7. Cleaning, Quality Control, and Packaging Approved fridge magnets undergo a dust-free cleaning process to remove surface dust, fingerprints, and impurities, giving the product a pristine finish. A final comprehensive inspection is then performed to verify the pattern, dimensions, magnetic performance, and appearance against production standards. Depending on order requirements, products are packaged individually in PP bags, gift boxes, or bulk cartons, incorporating moisture-proof and crush-resistant protection to prevent scratches or deformation during transit—completing the entire production cycle from raw material to finished product.   Conclusion: Precision Equipment for High-Quality Fridge Magnets Behind a seemingly simple fridge magnet lies a standardized, refined industrial production process. From design and material selection, substrate forming, and pattern printing to the core stages of automated resin dispensing, curing, trimming, magnetic assembly, and quality inspection—every step influences the final product quality. As a core piece of equipment, the WELDO visual dispensing machine has revolutionized the traditional resin dispensing process. It resolves common issues associated with manual production—such as low precision, poor yield rates, and inconsistency—enabling mass-produced fridge magnets to achieve crystal-clear resin surfaces, uniform texture, and high durability. It is the key factor in elevating the quality of today's high-end cultural/creative and custom fridge magnets.

Tips for the production of Visual Dispensing Machine for sticker products | WELDO Visual Dispensing Machine Operation Dodge Guide  WELDO has many customers around the world who produce sticker products, such as Canada, Mexico, Brazil, Russia, the United States, Poland, Japan, Turkey, Colombia, etc. All of them are using our Visual Dispensing Machine for production.  Whether it's self-adhesive stickers, label stickers, decorative stickers, or hardware sticker accessories, all benefit from the Glue Dispenser Machine to enhance efficiency. When many customers first install the machine or rush to complete large orders, problems such as glue overflow, glue leakage, sticker displacement, and poor curing often occur. This not only wastes glue but also delays the delivery date. Based on the extensive experience of WELDO engineers in training customers' factories on operating visual dispensers, this article will clearly explain the key issues that need to be paid attention to throughout the sticker dispensing production process.  1. Adhesive tape materials and fixtures The material of the adhesive tape is soft. When using thin PVC, transparent PET, or paper-based adhesive tapes, they tend to stretch and deform easily under force. Before using WELDO's Precision Dispenser, the working platforms of both sides should be cleaned thoroughly to ensure no residual glue or dust. Place the adhesive tape flat on the aluminum plate and fix it evenly using a strip or vacuum suction. There should be no wrinkles or curled edges. If making continuous roll-type adhesive tapes for mass production, the feeding speed should match the dispensing rhythm of the equipment. If the feeding speed is too fast, the adhesive tape will be pulled, causing deviations in the coordinates captured by the camera of the AB Glue Epoxy Dispensing Machine and resulting in incorrect dispensing positions. 2. Adhesive Materials and Squeegee Parameter Settings Sticker products have very high requirements for controlling the amount of glue. If there is too much glue, it will overflow and contaminate the surface of the sticker. If there is too little glue, it will not stick firmly and may come off. WELDO's Glue Dispensing Systems support the setting of precise dispensing quantity, dispensing speed, dispensing height, dispensing pressure and other parameters, which can be adapted to different products. The type of adhesive should be selected based on the sticker material. For example, transparent epoxy resin and UV glue can be used for paper stickers, while low fog UV glue should be chosen for transparent PET stickers to avoid yellowing of the sticker after adhesive curing. The adhesive storage environment should be kept at a constant temperature. Low-temperature adhesive will thicken, leading to uneven adhesive dispensing. Before mass production, the heating time on the Sticker Doming Machine can be set in advance to preheat the adhesive.  3. Product Solidification and Storage After the dispensing process is completed, the solidification and storage of the stickers are also very important. The curing of stickers requires strict control over the curing power and the duration of irradiation. It is necessary to avoid the situation where the adhesive force is insufficient if the curing time is too short, or the stickers turn yellow and become brittle if the curing time is too long. Slow-drying glue that has been dispensed at room temperature cannot be stacked immediately. If squeezed while still wet, the stickers will stick to each other. In addition, after the completion of dispensing, semi-finished products should be stored in a humid environment in the workshop, which will reduce the adhesion of glue, and the stickers will fall off and be reworked in the later stage, increasing labor costs.  4. Daily Maintenance and Cleaning If equipment maintenance is neglected during long-term production orders, the failure rate of the AB Glue Dispenser Machine will continue to rise, delaying the delivery of sticker orders. UV Resin Doming Machine relies on high-definition camera to locate the contour of the sticker, and the dirt of the lens will directly affect the product recognition. Dust in the workshop and the splashing of glue mist are prone to adhere to the lens. It is recommended to wipe the lens with a dust-free cloth after each shutdown and production stop. Do not use paper towels or cloth strips to directly wipe it, as it may scratch the lens. The guide regularly wipe the lubricating oil to prevent the mechanical position from stalling; the cleaning of the valve body is also very important. Do not allow the glue material to solidify in the valve body, which would affect its use. The residual glue in the material bucket and pipeline should be cleaned regularly. Mixing different types of glue may cause lumps and blockage of the valve body.    Summary Sticker products are produced by our Automatic Doming Machine. The advantage lies in high precision and large-scale automated processing. However, the yield rate is not determined by the single performance of the equipment, but by the synchronous control of five steps: material matching, visual adjustment, speed parameters, curing process, and daily maintenance.

Comprehensive comparison of pneumatic jet valves, piezoelectric jet valves, and screw valves: Glue selection - Compatibility guide  The VISUAL DISPENSING MACHINE of WELDO is a key equipment for many factories in the production of refrigerator stickers, key chains, badge gifts, accessories, hair clips, etc. This equipment offers various configurations for customers to choose from. Selecting the correct and suitable VISUAL DISPENSING MACHINE and glue for the production of your factory can help customers avoid common problems such as wire drawing, trailing, glue leakage, uneven glue dots, and needle blockage in the products, thereby improving the yield rate of the production line and reducing the loss of glue and labor debugging costs. The dispensing valve of WELDO is equipped with four types: pneumatic jet valve, piezoelectric jet valve, screw valve, and precision dispensing valve. These four types of valve bodies have completely different driving methods, glue output principles, compatibility with glue viscosity, dispensing accuracy, and procurement and maintenance costs. This article will analyze these four dispensing valves to help customers accurately select the machine suitable for their factory's production.  Pneumatic Jet Valve The pneumatic jet valve operates by using compressed air to drive the striker inside the valve body to move. The striker's return motion then releases the glue in the gap, spraying it from the nozzle in a regular frequency without touching the product. With the VISUAL DISPENSING MACHINE using this pneumatic jet valve, there is no need to worry about scratching the product because it uses pneumatic non-contact glue spraying, eliminating the need for Z-axis height adjustment. This valve body has moderate procurement cost and maintenance cost. The valve body is equipped with a heating block, featuring excellent high-temperature resistance, and can easily handle products with high viscosity during use. The wear parts are durable, and most are made of tungsten steel. The failure rate is low for large-scale continuous production, with extremely high cost-effectiveness, making it suitable for factories with limited budgets. It is very cost-effective. It is suitable for the production of products using hot melt glue, epoxy resin, silicone, paint and varnish, etc. However, this pneumatic jet valve needs to be used together with an air compressor and a stable pressure source. If the air pressure is unstable, it is prone to uneven glue application; the response speed and precision of the pneumatic jet valve are much lower than those of the piezoelectric jet valve, and it cannot perform fine and precise glue application.    Piezoelectric Jet Valve The piezoelectric jet valve uses piezoelectric ceramic to drive the glue technology. When the piezoelectric stack in the valve body undergoes mechanical deformation under the voltage switching, it uses the lever principle to drive the striker to move up and down, forming piston movement. The striker impacts the nozzle during the piston movement, thereby causing the fluid to be ejected. The entire process does not require auxiliary compressed air, completely eliminating the outgassing error caused by compressed air. The entire process is non-contact and remote airless dispensing, with a fast response speed and stable production unaffected by the air source. The operation is quiet during operation and suitable for the operation of precision products. The valve body of the VISUAL DISPENSING MACHINE using the piezoelectric jet valve adopts a rapid upper-end correction method. Through adjustment using the scale screw at the upper end of the valve body to adjust the height of the striker, the alignment of the nozzle and the striker is corrected. The purchase cost and maintenance cost of this valve body are relatively high. The core component of the piezoelectric ceramic has poor heat resistance, and there is a limit on the number of operations. After more than 10,000 operations, the electrical properties of the ceramic decrease; the piezoelectric striker cannot be forcibly disassembled. Due to the ceramic core being more affected by the operating environment, it is necessary to maintain a clean operating environment without obvious visible particles or debris, and keep it dry.  Screw valve The screw valve precisely controls the rotation speed and forward and reverse rotation time of the screw through a servo motor. The valve body adopts a rotor and stator combined structure. In the closed space, the fluid is conveyed forward by the rotation of the rotor. When the rotor continuously rotates in the stator cavity, due to the effect of pressure, it moves smoothly and uniformly from the feed end to the discharge end of the valve, thus completing the stable transportation of the fluid. VISUAL DISPENSING MACHINE with screw valve glue compatibility is extremely strong. By using the online mixing glue method, it is very suitable for quick-drying reactive glue, directly compatible with two-component AB glue ratio DISPENSING. This valve body is used in combination with WELDO's 741 precision dispensing valve. It cannot achieve remote spraying; it must contact the workpiece for dispensing. It needs to be coordinated with the Z-axis lifting movement. The rotor inside the piston is a wear-prone part. Long-term use will cause wear, and it needs to be replaced regularly. After each work is completed, the valve body needs to be cleaned. If the glue solidifies in the valve body, it will cause the inability to discharge normally. Mixing different adhesives is prone to produce lumps and block the valve body.    The viscosity of the glue is the first criterion for selection in the DISPENSING MACHINE. 1. For some low-viscosity glues, such as UV glue, water-based glue, and glue for filling the bottom of chips, the best choice is the piezoelectric jetting valve. It can precisely and accurately position and apply the glue without deviation or spread. 2. For medium-viscosity glues, approximately ranging from 10,000 to 100,000 cps, like epoxy resin, AB glue, silicone, and paint, for mass production with high speed, the pneumatic jetting valve is the best choice. For fine line drawing and continuous glue application, the piezoelectric valve should be selected, ensuring worry-free rapid production. 3. For high-viscosity glues, approximately ranging from 100,000 cps, the screw valve or pneumatic jetting valve can be chosen for stable glue output and precise quantitative accuracy.    If you are unsure about which type of valve body to choose, please feel free to contact us. We will customize a unique visual dispensing solution specifically for you based on our own glue parameters and product dimensions.

Four Key Factors of PVC Dispensing Production   Worker: Programmers, Operators Machine: PVC Dispensing Machine, Oven, Robot Production Line, Machine Layout Material: Viscosity stability/fluidity Mold: Standardized mold, proper size Core of Stable and Efficient Production Standardization is the key to stable, efficient automated production. 1.Standardized mold size, stable material ratio, consistent mold temperature change. 2.Stable material viscosity. It greatly affected by workshop temperature; So we create a stable temperature field on production equipment. 3.Optimize bottlenecks based on process cycle times to boost unit output. 4 Select reasonable equipment, layouts, and advanced processes for PVC dispensing production. Production Factor -- Worker Program and process design: Establish production takt time based on your products, then select suitable equipment and processes. For equipment that has already been purchased, we need calculate the production cycle time; then design the dispensing times for the face colors and the base color. Subsequently, we determine the suitable number of parallel dispensing heads—avoiding the blind addition of extra heads or over sizing molds. Production Factor -- Machine Weldo PVC Dispensing Machine Improvements Weldo Oven Improvements Weldo Robot Production Line Improvements Production factors — raw materials — PVC paste resin solution (PVC material) When selecting raw materials, choose an oil with low viscosity and good fluidity for proper mixing. This ensures faster production speed, superior flowability, and reduced likelihood of void formation in the PVC paste resin solution (PVC material). In production process, the transparent mixture obtained through thorough automatic stirring is first subjected to vacuum extraction, followed by color paste addition for coloring and another vacuum step before production commences. If the material is stored for an extended period, re-vacuum extraction is required to prevent surface bubbling (known as "matted material"). Production factors — Moulds Size of the mold The general mold size is 200mm*250mm.(for Products with relatively thin lines) The mold size in the right image is approximately 280*220mm, which is too large. Large molds are prone to deformation, resulting in uneven dispensing and uneven heating during baking, leading to defective products. The thickness of the mold, if the product is large, should be appropriately increased. Generally, the thickness of molds larger than 400*400mm should be 10-12mm. The aluminum material for mold opening needs to be milled flat on one side first, and then milled flat on the other side before mold opening. After each day's production, remove carbon deposits and dirt from the bottom of the mold to keep the bottom of the mold clean and flat. Compatible Mold Design For multi-size products, design spacing based on the largest size; smaller sizes use the same spacing for consistent needle alignment. More molds/cavities boost output but depend on order volume; control mold quantity as needed. For similar-sized products, standardize mold thickness, size, and cavity spacing to avoid frequent needle/needle position adjustments. For small orders, use 1–2 larger molds with multiple product molds on the same machine to increase production flexibility. Summary Weldo has been committed to promoting automated droplet molding production for 19 years, from single automatic machines to fully robotic production lines. Over 1,000 factories worldwide use our equipment. We are committed to promoting China's advanced PVC Dispensing production equipment and production technology to global customers. If you have any questions about the selection of Weldo PVC Dispensing equipment and production processes, feel free to consult and communicate with us.

What's the difference between epoxy A and B?   Don't worry, adhesives have more "personality" than you think!   Many people who encounter AB epoxy for the first time often ask the crucial question: What's the difference between epoxy A and B? It sounds like a chemistry exam question, but the answer isn't complicated at all.   Simply put: Component A is the "main ingredient," and component B is the "catalyst." Neither works alone; they only work together. It's like coffee and milk; they're incomplete without each other.   In actual production, the unsung hero that ensures A and B work together harmoniously without problems is the— Visual Dispensing Machine.   Why is an AB Glue Dispenser indispensable for AB epoxy?   You might have tried mixing the glue manually: A little too much today, a little too little tomorrow, The day after, it solidifies in the cup, and your boss freezes in place.   That's where the AB Glue Dispenser comes in. Its core function is simple: consistent ratio, precise dispensing, and reliable performance.   A more advanced version is called the AB Glue Dispenser Machine. And an even more professional version is the AB Epoxy Dispensing Machine. They can precisely control the A/B ratio, preventing mistakes caused by "a shaky hand."   From trademarks to hairbrushes, adhesives are actually very busy.   Did you think AB epoxy is only used in electronics? You're greatly underestimating its versatility!   With the help of the Visual Dispensing Machine, AB glue has successfully penetrated various application scenarios, such as:   trademark painting (trademark dispensing, the first impression of a brand)   label dispensing (label gluing, sticking firmly)   hanging gluing (hanging item bonding, guaranteed not to fall off)   brooch dispensing (brooch gluing, elegant and secure)   shift knob painting (gear shift knob coating, perfect feel)   license tag paint (license plate coating, weatherproof)   hairbrush glue powering (hairbrush gluing, preventing breakage)   ornament dispensing (ornament gluing, precision is key)   zipper puller painting (zipper puller coating, durable for daily use)   logo painting (Logo dispensing, must be three-dimensional)   electronic-pouring sealant (electronic potting, maximum security)   elephantine sealant (large-volume potting, high quantity but high quality)   sealing AB adhesive (AB sealant, reliable sealing)   capacitance sealant (capacitor sealing, not a single drop wasted)   Behind these scenarios, there is often an Epoxy Resin Doming Machine, responsible for dispensing the glue perfectly round and full, even satisfying those with OCD.   So, is the difference between epoxy A and B important?   Yes, but what's more important is how you use them.   Without a reliable AB Glue Dispenser Machine, no matter how good A is, or how expensive B is, it can all end up as a "disaster."   A mature Visual Dispensing Machine, allows epoxy A and B to perform their respective functions, work together harmoniously, and cure quickly, while also helping you improve yield, save labor, and reduce the number of times your boss frowns.   In short, an informal but very practical statement:   The difference between epoxy A and B is chemistry. The existence of the AB glue Epoxy dispensing Machine is a productivity.   The glue isn't to blame, The ratio is the key, And the ratio is best left to the machine.

Unveiling the Secrets: Where Do the Profits and Costs of Drip Molding Primarily Lie? Industries Involved: Garment accessories, soft PVC drip molding, soft PVC double-sided zippers, single-sided zippers, shoe embellishments, shoe uppers, shoe soles, shoe trims, luggage pull tabs, single-sided pull tabs, double-sided pull tabs, motorcycle stickers, glove embossing.   For manufacturers of soft PVC drip molding labels, the business is primarily processing-based, without retail sales.  Orders come from garment factories, shoe factories, gift trading companies, and cross-border e-commerce businesses. Customers provide samples or design drawings for production.  Production costs are high, and manufacturers rely on large orders to maintain meager profits. Drip molding production costs mainly involve three aspects: 1. Labor 2. Materials 3. Molds Labor:  Recruiting and managing labor is difficult. The drip molding industry is very labor-intensive, and labor costs are high with high employee turnover. Labor costs constitute the largest portion of expenses. Materials: All export products require high-quality materials, resulting in high costs. Molds: Mold costs are very high.  Each sample requires the development of new molds. Every large production run requires the carving of new molds, unless the customer repeatedly places orders, which can save some mold costs, provided there is a large inventory of molds. Therefore, mold costs are also very high. Basic PVC patch production Line：   * dust fliter sand blast machine——it is to treat mold before inject PVC   *mixing machine——it is to mix pvc raw material   *vaccum pump + vacuum mixing barrel——this machine is to take air out from pvc  raw material （Ensure the products no bubble)    * PVC patch dispensing machine with UV light——high efficiency and high quality to produce PVC patch   *oven­——this is to heat and cool mold

Those who frequently work with epoxy resin, whether for sticker doming, parts bonding, or operating equipment like Visual Dispensing Machines and AB Glue Dispensers, have likely encountered a frustrating problem – epoxy resin failing to adhere to certain materials.  It's not that the epoxy itself is defective, but rather that some materials are inherently incompatible with it. Today, let's discuss which materials epoxy resin won't adhere to, or won't adhere to securely.   First and foremost is silicone. Whether it's soft silicone products or silicone-coated surfaces, epoxy resin has great difficulty adhering to them. A friend once used an Epoxy Doming Machine to apply epoxy to silicone stickers, but the epoxy peeled off after curing – this is the reason. Silicone surfaces are extremely smooth and chemically stable; epoxy resin simply cannot penetrate and form a strong bond with it. Unless special surface treatment is applied beforehand, don't waste glue and time.   Next is polytetrafluoroethylene (PTFE, also known as Teflon). This material is familiar to most people; it's the coating used in non-stick pans. Its characteristic is "non-stick to everything." Not only does epoxy resin not adhere to it, but most adhesives are ineffective as well. If you need to use an AB Glue Dispenser Machine to apply adhesive to Teflon parts, the adhesive alone is completely useless. You need to perform special surface treatments such as sanding and etching to roughen the surface before you can achieve even a slightly improved adhesion.   Polyethylene (PE) and polypropylene (PP) plastics are also "enemies" of epoxy resin. These two plastics are commonly used in daily life and industry, such as in plastic containers, pipes, and parts. They have very low surface tension; when epoxy resin is applied, it automatically shrinks into droplets, making even adhesion impossible, let alone a strong bond after curing. A customer once asked why their AB Glue Epoxy Dispensing Machine couldn't bond PP plastic parts securely; the problem was with the material itself, not the machine operation.   Additionally, materials with oily, dusty, or waxy surfaces will also prevent epoxy resin from adhering. Although this isn't a problem with the material itself, it's one of the most easily overlooked aspects in practical application. Whether you're using a sticker doming machine to apply epoxy resin to stickers or using ordinary AB glue to bond parts, if the material surface has oil, dust, or has been waxed, the epoxy resin will only adhere to these impurities and won't bond with the base material.  It will easily peel off after curing. Therefore, it's crucial to clean the surface thoroughly before operation, ensuring degreasing and dust removal are completed.   Some particularly smooth metal surfaces, such as polished stainless steel and aluminum products, also exhibit poor adhesion with epoxy resin. While not completely non-adhesive like Teflon, the bonding strength after curing is insufficient, and the bond can easily break under stress. In this case, in addition to cleaning the surface, you can lightly sand it to create fine textures, helping the epoxy resin to "grip" the material better.   In summary, although epoxy resin has strong adhesive properties and can handle most situations when used with equipment like Visual Dispensing Machines and Epoxy Doming Machines, it becomes "ineffective" when dealing with silicone, Teflon, PE/PP plastics, and materials with unclean or excessively smooth surfaces. Before starting work, always confirm the material and perform necessary surface treatment to avoid wasted effort.

PVC products processing steps Step 1:  Used Mixing machine to mix PVC raw material, include PVC powder, PVC oil, soybean oil, PVC colors , to get liquid PVC material, which can be used on material bottle of PVC dispensing machine.HOW TO PREPARE PVC RESIN VIDEO  Step 2: put liquid PVC material in vacuum mixing barrel to take air out from PVC material. Step 3: Put PVC material in material bottle on 12 colors PVC dispensing machine ,  make processing program and download to machine, then used 12 colors PVC dispensing machine to   fill face color on mold. Step 4: Put mold which been filled with face color on oven to heating and curing. Step 5:When face color finished curing, take mold on 12 colors dispensing machine to fill base color. Step 6:After finished fill base color on mold, put mold in oven to heating and curing base color. If single side PVC products, after this step, products are formed, just need to take out from mold and quality inspection.

Many people, upon hearing "AB epoxy resin," immediately think, "Isn't that for industrial use?  It's far removed from daily life, right?" Actually, that's not the case. Many delicate small objects around us, such as metal badges, hairpins, jewelry, and nail art decorations, often use AB epoxy resin, combined with equipment like Visual Dispensing Machines and AB Glue Dispenser Machines for dispensing.   I. What exactly is AB epoxy resin?   Simply put, AB epoxy resin is a type of adhesive that requires mixing two components before use.   Component A: Primarily resin   Component B: Primarily hardener   When components A and B are mixed in a fixed ratio, they gradually harden, eventually forming a transparent, strong, and durable adhesive layer. This is why AB epoxy resin is often used for sealing, fixing, filling, and decoration.   For example:   The crystal-clear "crystal-like" surface layer on badges   The high-quality transparent protective layer on hairpins and jewelry   The adhesive layer used to fix glitter and small decorations in nail art   Many of these effects are achieved with AB epoxy resin.   II. Why is automatic dispensing essential for AB epoxy resin?   Although AB glue is useful, it has a "quirk"— The ratio must be precise, and the amount of glue must be consistent.   If dispensing is done manually:   Inaccurate ratios can lead to softness or brittleness.   Uneven glue amounts result in an unattractive appearance.   Poor repeatability makes it difficult to achieve consistency in mass production.   This is where the AB Glue Dispenser comes in handy.   III. What problems can the AB Glue Dispenser solve?   The AB Glue Dispenser is a device specifically designed for two-component adhesives, capable of automatically mixing and dispensing the glue.   Its advantages can be summarized in three points:   Stable ratio Components A and B are dispensed strictly according to the set ratio, minimizing problems.   Even dispensing The dispensed glue is consistent in thickness, resulting in a better appearance.   Higher efficiency Especially suitable for mass production of small products such as metal badges, hairpins, jewelry, and nail art decorations.   For higher automation requirements, an AB Glue Dispenser Machine is used to achieve continuous and stable production.   IV. Why is the Visual Dispensing Machine becoming increasingly popular? Many products now have irregular shapes, such as:   Irregularly shaped metal badges   Curved hair clips   Multi-shaped nail art pieces   In these cases, relying solely on fixed-program dispensing is often insufficient.   A Visual Dispensing Machine uses a vision system to "see" the product:   Automatically identifies dispensing locations   Automatically corrects deviations   Easier switching between different styles   When a Visual Dispensing Machine is used in conjunction with an AB glue Epoxy dispensing Machine, it not only dispenses accurately but also beautifully, making it ideal for consumer products with high aesthetic requirements.   V.  Everyday Applications of AB glue Epoxy dispensing Machines   Many people think that AB glue Epoxy dispensing Machines are only used in the electronics industry, but they are also very common in the field of everyday products, such as:   Metal badges: Surface dispensing to create a three-dimensional transparent effect   Hair clips and jewelry: Fixing decorative parts, improving texture and durability   Nail art decorations: Precise dispensing to fix glitter and rhinestones   DIY handmade products: Small-batch, high-repetition dispensing needs   Through automatic dispensing, the appearance is not only more refined, but the consistency of the finished product is also better.   VI. Summary   AB epoxy resin is not a distant concept; it has already integrated into our daily lives. And AB Glue Dispensers, AB Glue Dispenser Machines, Visual Dispensing Machines, and AB glue Epoxy dispensing Machines are the key tools that enable the high-quality and stable production of these small and beautiful products.   Whether it's badges, jewelry, or nail art decorations, if you want them to look good and be durable, AB epoxy resin and automatic dispensing equipment are crucial components.

A phone call from Russia: one piece of equipment, a friendship, and an international technical exchange   Today, we received a call from our old friend Viktor in Russia. His voice was as friendly as ever. He first inquired about our recent situation and joked that receiving the equipment we sent in the cold winter felt like receiving a "heartwarming gift from China."   From smooth delivery to practical operational issues   Last month, the AB Glue Dispenser Machine we shipped to Russia arrived successfully. Viktor was very satisfied with the appearance, workmanship, and packaging protection after the long-distance transportation. However, when the equipment was actually put into production, he encountered some problems:   1. The epoxy injection control was not precise enough; sometimes there was insufficient filling, and sometimes there was a slight overflow.   2. The heating temperature settings were uncertain for different production batches.   3. He was not familiar with daily cleaning and maintenance and was worried that it would affect the equipment's lifespan.   These seemingly minor problems directly affected production efficiency and product quality.       Weldo Automatic: Providing not only equipment, but also support and confidence   After understanding the situation, we immediately explained to him that Weldo Automatic has a professional and experienced after-sales team that provides technical support to customers worldwide. Weldo Automatic is not just an equipment manufacturer, but also a reliable technical partner for its customers.   We can provide various support methods:   Online video support: Real-time connection and step-by-step guidance;   Engineer on-site service: Engineers on-site for debugging, training, and optimization;   Factory training visit: Face-to-face learning at the factory to gain an in-depth understanding of the equipment.   An exciting trip to China   When Viktor learned that he could not only receive online technical support but also personally come to China to learn about the installation, debugging, operation, and maintenance of the AB glue Epoxy dispensing machine at our factory, he was very surprised and excited. He said that this would not only solve the current problems but also help his team fully utilize the equipment's performance and improve production efficiency and product quality.   We quickly confirmed the visit time and prepared a detailed training plan, including equipment working principles, parameter settings, material applications, daily maintenance, and troubleshooting, to ensure that he could operate the equipment independently, skillfully, and confidently after the training.

1.Sandblasting Machine   This equipment is used to treat the surface of product molds. It removes dust, oil, and impurities from the mold, improving the adhesion between the PVC material and the mold. Additionally, when using needle dispensing, sometimes the mold surface can be scratched, resulting in defective PVC label products. Our sandblasting machine can be used to treat the mold in such cases. A clean mold surface ensures clear details, better color representation, and higher product quality. 2.PVC paste mixing machine   The paste mixing machine is used to uniformly mix PVC powder and PVC oil, and to thoroughly mix the resulting PVC paste with pigments and additives. The uniform mixing ensures stable product color, consistent viscosity, and smooth material flow, which is crucial for the quality of PVC labels.   3.Vacuum Pump + Vacuum Mixing Barrel   The Vacuum Pumps and Vacuum Mixing Barrel need to be used together. After the PVC raw materials are thoroughly mixed, they are transferred to the vacuum tank. The vacuum pump extracts air from the PVC raw materials, preventing bubbles from appearing in the PVC labels. Vacuum pumps are usually available in 15L, 30L, and 70L specifications, which can be selected according to your order volume.   4.PVC Dispensing Machine with UV lamp   This is the core equipment of the PVC patch production line. The dispensing machine accurately fills the prepared PVC material into the mold according to the product design. UV light irradiation allows for simple surface curing of small areas of color, eliminating the need for the fabric part to be baked in an oven, greatly increasing the production speed of PVC patches.   5.PVC Baking Oven   After the PVC raw materials are dispensed, the molds are sent into an electric oven for heating and curing. The oven has two independent enclosed spaces, allowing for different heating times and temperatures to be set.  Once the set time is reached, the molds are automatically ejected from the oven, and cold water is injected onto the cooling table to cool the molds. After the molds cool, workers can remove the PVC patches from the molds using a picking tool.   The above is a complete set of equipment for a complete PVC patch production line.   This production line is widely used for making PVC logos, PVC brand patches, PVC military patches, PVC cartoon patches, PVC shoe labels, and various PVC promotional products.

The manufacturing industry is placing increasingly higher demands on dispensing machines, requiring accuracy, stability, and intelligence. Based on whether they utilize machine vision, there are primarily these two types. So, what exactly are the differences between them?   Below, we'll briefly discuss their differences in terms of working method, advantages, and applicable products.   I. Different Working Methods?   1. Non-Visual Dispensing Machines This method is more traditional, relying on mechanical positioning and pre-set paths for dispensing. Before production, fixtures, stops, or manual teaching are used to fix the product position and path. Characteristics: Fixed path; High requirements for product placement consistency; Cannot recognize deviations or automatically correct them. If the product is misplaced, rotated, or has dimensional tolerances, the dispensing effect is easily affected.   2. Visual Dispensing Machines This adds an industrial camera, light source, and vision algorithms to the traditional dispensing process. Before dispensing, the machine "looks" at the product, identifies the actual position, angle, and features through photography, and automatically adjusts the dispensing path. The process is roughly: Camera takes a picture; Vision system identifies features; System automatically corrects the position; Precise dispensing is completed. With the added "seeing" step, stable dispensing is possible even if the products are not perfectly aligned.   II. What are their respective advantages?   1. Advantages of Non-Visual Dispensing Machines Simple structure, no vision system, lower cost, suitable for projects with limited budgets. Intuitive operation and programming, simple debugging and maintenance, and low technical requirements for personnel. Not affected by light, reflections, and other factors, and has lower environmental requirements.   2. Advantages of Visual Dispensing Machines The biggest advantage is "accuracy." Visual positioning and automatic correction result in more precise dispensing positions and better product consistency. Can automatically recognize product displacement and rotation, reducing manual adjustments and making the process more stable. When changing products or orders, switching visual templates allows for quick adaptation, improving efficiency. With stable positioning, the cycle time is also stable, suitable for long-term mass production. In addition, visual positioning reduces the reliance on high-precision fixtures, saving considerable fixture costs in the long run.   III. What products are they suitable for? 1. Products Suitable for Non-Visual Dispensing Machines Suitable for products with simple structures, consistent materials, and less stringent accuracy requirements. For example: Dispensing for home appliance structural components; Ordinary LED packaging; Medium and low-precision electronic modules; Sealing and fixing dispensing for plastic parts.   2. Products Suitable for Visual Dispensing Machines Suitable for products requiring high precision, stability, and flexibility, especially small parts, complex structures, or situations where the position is not fixed. For example: Consumer electronics such as mobile phones and tablets; Precision product dispensing; New energy batteries and automotive electronics; Metal nameplates, precision badges, high-end commemorative coins, and craft jewelry.   IV. How to Choose the Right Equipment?   When choosing equipment, consider these aspects: Dispensing accuracy requirements; Product consistency; Feeding method; Production cycle time; Budget; Whether you will need to change products or upgrade the production line in the future.   In general, if you prioritize cost control and stable mass production, Non-Visual Dispensing Machines are more suitable; if you are more concerned with precision, yield, and production flexibility, Visual Dispensing Machines will be more appropriate.   V. Summary   Visual Dispensing Machines and Non-Visual Dispensing Machines are not simply a matter of high-end versus low-end, but rather two different solutions for different products and needs. As manufacturing moves towards higher precision and greater intelligence, Visual Dispensing Machines will become increasingly common.   If you are considering upgrading your dispensing process, WELDO's Visual Dispensing Machines are a worthwhile option.   Only by choosing the right equipment based on product characteristics can you control costs while ensuring high product quality.
