Abstract

Injection molding technology has been in development for almost 150 years. Injection molding is a molding technology that melts the material with the aid of a screw and an external heating device and then injects it into a mold to form the corresponding product as the mold cools. At present, many types of materials can be used to mold products by injection molding. Many requirements and problems in the processing of different materials have also caursed the birth of many molding processes. At present, injection molding has been applied in many fields, from daily necessities that are closely related to our lives to parts and components in the aerospace field. At present, injection molding still faces the challenges of processing new materials, and the continuous improvement of the existing equipment technology is required for the continuous development of injection molding.
