Injection molding

- Sep 30, 2020-

Injection molding is a kind of molding method for industrial products. Rubber injection molding and plastic injection molding are usually used for products. Injection molding can also be divided into injection molding, pressing and die casting.

Injection molding machine (hereinafter referred to as injection molding machine or injection molding machine) is the main molding equipment to make thermoplastic or thermosetting materials into various shapes of plastic products by plastic molding mold. Injection molding is realized by injection molding machine and mold.

1. Rubber injection molding: rubber injection molding is a production method that directly injects rubber from the barrel into the mold for vulcanization. The advantages of rubber injection molding are: although it is intermittent operation, the molding cycle is short, the production efficiency is high, the embryo preparation process is cancelled, the labor intensity is small, and the product quality is excellent.

2. Plastic injection: plastic injection molding is a method of plastic products. The molten plastic is injected into the mold of plastic products by pressure, and then cooled to form various plastic parts. There are special mechanical injection molding machines for injection molding. At present, the most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc.

3. Injection molding: the shape obtained is often the final product, and no other processing is required before installation or use as the final product. Many details, such as bumps, ribs, and threads, can be molded in one step of injection molding.
