What is injection molding?

Injection molding is a method for the production of industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method.

Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes with plastic molding molds. Injection molding is realized through injection molding machines and molds.

main type

1. Rubber injection molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into the model for vulcanization. The advantages of rubber injection molding are: although it is an intermittent operation, the molding cycle is short, the production efficiency is high, the blank preparation process is canceled, the labor intensity is small, and the product quality is excellent.

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

3. Molding and injection molding: The resulting shape is often the final product, and no other processing is required before installation or use as the final product. Many details, such as bosses, ribs, threads, can be formed in a single injection molding operation.
