What is injection molding?

Injection molding is a process for manufacturing plastic products, also known as plastic injection molding. It is to inject molten plastic into a mold and form a product of the desired shape and size after cooling and solidification. Mainly, granular or powdery raw materials are added to the silo of the injection molding machine. After being heated and melted, they become fluid. When the screw or piston rod of the injection molding machine moves, they enter the mold through the nozzle and the pouring system of the die-casting mold. The concave mold is shaped in the concave mold of the mold. After the product is completely solidified, the mold is opened and the finished product is taken out.
