  • Six Ways to Increase Tooling Life
    Six Ways to Increase Tooling Life
    March 12, 2022

    Tooling life has been an important factor affecting the profitability of an injection mold maker. If reasonable methods can be used to make mold life beyond the design requirements, then the profitability of the company will be greatly improved. Here are some ways to improve mold life. 1. Correctly setting the mold locking force It is very important to set the locking force correctly for each mold. If an operator uses too little locking force, injection pressure can exceed the mold locking force and blow open the mold during the injection process. If an operator uses excessive locking force, the injection molding machine will apply excessive compression on parting lines, vent areas and mold components, thus damaging the tool. To avoid these situations, 2. Setting low pressure close. Setting up a low-pressure close on the press to protect the mold. Set the high-pressure lock position to 0.05 higher than the actual mold contact position. Gradually reduce low pressure closing pressure until the mold is not locked. At this time, pressure rises slowly, allowing just enough pressure for the mold to transition from low-pressure to high-pressure lock up. What’s more, set the mold closer time to 0.5 secs higher than the actual mold closing time requirement. For example, if the actual mold closing time is 0.85 seconds, set the mold closing timer to 1.35 seconds. 3. Correctly setting the mold opening and closing Clamp speed affects cycle time, but faster speeds are not better, since they can cause tool wear or damage. It should ensure that the transition from close fast to close slow is smooth and the slow condition occurs before the pins and components match up. Make sure the transition between mold breakaway and mold open fast is also smooth, with the open fast segment occurring after all of the components are out of the mold. 4. Correctly setting up ejection Incorrect setting points can shorten tool life due to excessive stroke or improper part ejection, resulting in part closure between mold halves. It is necessary to eject the parts from the mold correctly according to the separation amount required by the actual product. Too much ejection will have too much pressure on the ejector pins. In addition to the injection volume, injection pressure should not be set too large, ensure pressure set points only use the required amount. 5. Correctly setting mold watering Mold temperature is too high and will have a negative impact on mold life, so mold temperature limit to a minimum requirement for acceptable part aesthetics. Also, ensure that the temperature difference between the moving tool side and the fixed tool side does not exceed 6 °C. Higher above this scope will lead to difference of the thermal deformation between the two sides of the mold, resulting in the problem of the opening and closing of the mold is not smooth, and the wear or damage of the mold. 6. Mold cleaning and maintenance In the production environment, always check, clean and grease the ...

  • Design for manufacturing for Plastic injection components
    Design for manufacturing for Plastic injection components
    January 06, 2023

    Design for Manufacturing (DFM) for Plastic Injection Mold What do you do when process and product design go hand in hand? Before start to make plastic injection mold, the first step is design for Manufacturing (DFM). you get a quicker time to win market, better design, cost savings, guaranteed feasibility, and part failure prevention. DFM is a product design that eases the end-to-end manufacturing process for complex plastic components while optimizing quality and reducing waste. At Yuan fang, this highly collaborative customized process is one of our specialties. Let's take a closer look at DFM. What is Design for Manufacturing (DFM)? Design for Manufacturing is an optimized plastic part design process that lowers overall costs while creating a better design and an easier to manufacture product. DFM combines the design requirements of a product with its production method, resulting in custom-molded, close-tolerance parts that meet or exceed industry standards. This critical part of the product development cycle can take several weeks, depending on the complexity of the design. DFM should be implemented early in the development process. Neglecting it nearly always results in catching manufacturability issues too late, which leads to multiple design iterations, increased expenses, and a greater risk of product flaws. In highly regulated industries like automotive sector, medical technology, DFM is a must. Even the most minor change in a product after its kick off can take months to implement because it must comply with stringent industry regulations. DFM presents ways to optimize manufacturing before it even begins. What are the Benefits of DFM? One of the most significant benefits of Design for Manufacturing is the lower overall cost of production. An optimized design can reduce the number of processing steps, eliminate redundant design features, simplify assembly, and reduce the number of connectors or fittings needed in the finished product. Because the DFM process catches and removes mistakes or faults before production, the result is a higher-quality product that gets to market sooner. DFM helps prevent the production of simple designs with overly complex manufacturing processes or designs that seem inexpensive to produce but are too complicated or expensive to service later. What is the plastic injection molding process? There are five equally important principles of DFM. Designers and engineers must optimize each of these closely-intertwined focus areas to ensure the finished product is the best it can possibly be. Process Selecting the proper manufacturing process for your product is critical. Consider the number of parts needed, the type of materials needed, the complexity of the design, the tolerances required, and the budget for the whole project. Design Design for Manufacturing. The actual 2D/3D drawing or CAD model must conform to good manufacturing principles for your selected process. It makes the complexity of the design clear, fro...

  • 6 Step of Plastic Injection Molding
    6 Step of Plastic Injection Molding
    December 16, 2022

    Plastic injection molding is a fully customizable manufacturing process with various applications across industries. Injection molding is a common plastics part manufacturing process with various applications across the automotive, medical, consumer goods, electronics, energy, and food and beverage ect industries. It's so common that the global market size came in well over $200 billion in 2021, with significant growth predicted through 2030. Despite the ubiquity of injection-molded thermoplastics, most people are unaware of how much we depend on these products, nor do they consider the manufacturing method. We’d like to talk about plastic injection molding. What is Injection Molding? Injection molding is almost precisely what it sounds like: the manufacturing process of injecting molten material, in our case, thermoplastics, into a mold, then cooling and solidifying it to produce a part. Although it seems simple, it's an exacting, complex process well suited to manufacturing unusual shapes and large volumes of components. It's efficient, repeatable, and cost-effective without sacrificing quality.  Chances are you've encountered an injection molded component today, whether you know it or not. Injection molding technology produces lifesaving medical devices, auto parts, electronic switches and housings countless other items. Parts produced with injection molding are light, durable, and resistant to extremetemperatures, depending on the type of resin used. The Plastic Injection Molding Process 1) Designing and Prototyping Before molten plastic becomes a component, there must be a design. The DFM (design for manufacturability) process starts with blueprints, specs, and CAD files that are revised, tested, and refined until they are ready for production. The appropriate type of thermoplastic is chosen at this stage to ensure that the final component has the right properties. 2) Tooling Once the prototype is approved, the final plastic mold is created for mass production. Each mold consists of a  cavity (the fixed part that the plastic is injected into) and a core (a moving part that fits into the cavity to help form the component's final shape). Manufacturers custom build each mold in-house for maximum efficiency, quality, and cost savings. 3) Feeding and Melting Raw material of the chosen engineering-grade thermoplastic is fed into the hopper of an injection molding machine. A long, cylindrical heated barrel with an injection screw sits next to the hopper. A gate sits at the end of the barrel, and the mold tool is connected to the gate. The turning of the screw and the heat from the barrel gradually warm and melt the thermoplastic until it is molten and ready to inject. 4) Injection part When the molten plastic reaches the end of the barrel, the gate closes, and the injection screw moves back,         drawing through a set amount of plastic. As the pressure in the screw builds...
