1. Definition of Injection Molding Machine

Injection molding machine is the main molding equipment that uses plastic molds to make various shapes of plastic products from thermoplastic or thermosetting materials. Injection molding machines can be divided into vertical, horizontal, and vertical horizontal composite types according to the arrangement of injection devices and locking devices< a>

The working principle of an injection molding machine is similar to that of a syringe used for injection. It uses the thrust of a screw (or plunger) to inject the melted plastic (i.e. viscous flow state) that has already been plasticized into the closed mold cavity, and after solidification and shaping, the process of obtaining the product is carried out. Injection molding is a cyclic process, which mainly includes: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, and mold opening and picking up. After removing the plastic part, close the mold again and proceed to the next cycle< a>
