Plastic injection process

A mold is a tool for producing plastic products. It consists of several parts of a composition with a molding cavity.

The product is ejected from the mold through the injection system and the mold is closed. The next injection molding process, the entire injection molding process.

Mold meets process performance requirements

Mold manufacturing generally goes through forging, cutting, and heat treatment. In order to ensure the quality of mold manufacturing and reduce production costs, the material should have good ductility, machinability, hardenability, hardenability and grindability. It should also have a small tendency to oxidize, decarburize, and crack when deformed by quenching.
