Q1. What is a plastic injection molding?

There are many various ways to make products using plastic raw materials.

Among them, an injection molding is one of the manufacturing methods that can produce complex and diverse forms of products in mass scale.

Plastics is able to be used as raw material status, including powder, liquid and pellets, and it is divided into a non-renewable thermosetting resin and a renewable thermoplastic resin, and their forming methods is different little by little according to the status of raw materials. The injection molding using thermosetting resin is divided into a powder injection molding, or a liquid injection molding, according to the status of raw materials, and the injection molding using thermoplastic is called the injection molding generally.

A general injection molding using thermoplastic is a production method that melts the plastic raw materials in a heating cylinder and injects the melted material into an injection device in a mold, and then solidifies the material melted with a cooling device inside the mold, produces the shape within the mold.

The plastic products are produced using an injection molding, and the units of mold attaching, raw materials supplying and melting, are connected and operated as a one system.

Injection molding can produce the complex and various forms of products as the same shape in mass scale.

General injection molding refers to a method of production using thermoplastic resin.
