tpe packing materials manufacturer, TPE raw materials are used for secondary injection molding, glue-encapsulating and sticking, mainly because TPE raw materials have good anti-slip resistance and good elastic touch, which can enhance the touch feel of the product and enhance the grip. There are two main ways to achieve glue forming.
is 2Kinjection molding, that is, two-component molding or also called two-color injection molding. It is implemented on the two-color injection molding machine , injecting one material into a product, and then flips the mold on the two-color machine to the mold cavity corresponding to the other injection molding barrel, using this component as an insert, and injecting another material on it to form an integrated double-material product. Injection molding machine is a double-material barrel and a double-mold cavity. The injection molding process is that products of both materials are being produced at the same time, but the products of one cavity will enter the next cavity as inserts. The second type is called 2 step molding, which is translated as two-step injection molding. It is to mold a component of one material on an injection molding machine, then put the component as an insert into another mold, and then inject the second material into it. In general, the above two processes are collectively referred to as overmolding, namely, overmolding. This process has been used on engineering plastics for a long time. The adhesive in the elastomer application segment is just a special overmolding. Its specialty is that it uses soft TPE material as the second material component to cover the surface or part or inside of various hard ordinary plastics and engineering plastics to achieve the effect of multiple materials of a single component. Simply put, overmolding can be plastic-covered, soft glue-covered, and soft glue-covered. Glue wrapping is a habitual name, which is basically a specific overmolding process for soft glue-covered hard plastic.
TPE glue wrap manufacturers. As long as they make TPE raw materials, they can be called glue wrap manufacturers. Because the glue wrap formula is not very complicated, the common TPE glue wrapping materials include PP, ABS, PC, PA, and PS. In terms of difficulty, the glue wrapping PA (nylon) is higher. The glue wrapping material formula systems of PA66 and PA6 are different, and they also require the cooperation of molds and injection molding processing plants.
