Processing Technology Of Plastic Injection Molding Thermoplastic
- Jun 13, 2017 -

Thermoplastic Plastic Injection Molding This method is to melt the plastic material, and then inject it into the membrane cavity. Once the molten plastic enters the mold, it cold according to the mold cavity sample to form a certain shape. The resulting shape is often the final product, and no additional processing is required before installation or use as final product. A lot of detail, such as a bulge. Rib, thread, can be molded in the injection molding one-step operation. The injection moulding machine has two basic components: an injection device and a clamping device for melting and giving plastic to a person's mold. The function of the clamping device is: (1) Closing the mould under the condition of injecting pressure and (2) removing the product. The injection device melts the plastic before it is injected into the mold, and then controls the pressure and speed to inject the melt into the mold. At present, there are two types of injection device design: Screw-type pre-plasticizing or two-stage device, as well as reciprocating screw. The screw-type pre-plasticizing machine utilizes the plasticizing screw (first stage) to send the molten plastic to the feeding rod (second level).
