Production process analysis of power adapter:

1. The product is made of polycarbonate (PC) with shrinkage of 0.5% ~ 0.8%;

2. Mobile phone shell molding process - injection molding, also known as injection molding. Injection molding is a method of using injection molding machine (or injection machine) to inject thermoplastic melt into the mold under high pressure and obtain products after cooling and curing. Injection molding can also be used for the molding of thermosetting plastics and foamed plastics. Injection molding has the advantages of fast production speed, high efficiency, automatic operation, and can shape complex parts, which is especially suitable for mass production. The disadvantages are high cost of equipment and molds, difficult cleaning of injection molding machine, etc.

3. The surface finish of the product is required to be high, and the fluidity of PC is poor, so the process is usually filled with high mold temperature and high material temperature. Therefore, in order to improve the molding efficiency, point gate is adopted, and graded injection is adopted during injection molding.
