Description

Multi-station injection molding machine Technical Field The application relates to the technical field of injection molding machines, in particular to a multi-station injection molding machine. Background Injection molding machines are devices commonly used in the plastics processing industry, and are also known as injection molding machines or injection molding machines. It is a main forming equipment for making thermoplastic plastics or thermosetting plastics into various shaped plastic products by using plastic forming mould. The device is divided into vertical type, horizontal type and full-electric type.
