Injection molding is a method of industrial product production modeling. Rubber injection molding and plastic injection molding are masani used for products. Injection molding can also be divided into injection molding, molding and die casting.


Injection molding machine (hereinafter referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make thermoplastic or thermosetting materials into plastic products of various shapes.


1. Rubber injection molding: rubber injection molding is a production method of injecting rubber directly from the barrel into the mold 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 embryo preparation process is faalēaogā, 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 plastic product mold by pressure, cooled and molded to obtain all kinds of plastic parts. There is a mechanical injection molding machine specially used for injection molding. At present, 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 protrusions, ribs and threads, can be formed in one step of injection molding.
