Background
Injection molding, also called injection molding, is a molding method of injection and molding, which is a process of forming a molten raw material into a semi-finished product of a certain shape by pressing, injecting, cooling, releasing, and the like. The injection molding method has the advantages of high production speed, high efficiency, automation in operation, multiple colors and varieties, simplified and complex shapes, large to small sizes, accurate product size, easy updating of products, and capability of manufacturing products with complex shapes, and is suitable for the molding processing fields of mass production, products with complex shapes and the like. Along with the rapid development of economy, various plastic products enter the life of people, and injection molding is mostly adopted in the production of plastic products, namely, molten plastic is injected into a mold by an injection molding machine, and the plastic is taken out for post treatment after being cooled and solidified, so that the product can be obtained.
