Overview of Injection Molding Machine

Basic Definition and Functions of Injection Molding Machines

Injection molding machine, also known as injection molding apparatus or injection press, is a primary molding equipment used to produce various plastic products from thermoplastic or thermosetting plastics using plastic molding molds. It mainly comes in three types: vertical, horizontal, and fully electric.1. The working principle of the injection molding machine is to heat the plastic to a molten state, then apply high pressure to extrude it out of the mold cavity, completing the molding process.
