Background

Injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. The injection molding can be classified into injection molding and die casting. An injection molding machine (an injection machine or an injection molding machine for short) is a main molding device for making thermoplastic plastics or thermosetting materials into plastic products with various shapes by using a plastic molding die, and the injection molding is realized by the injection molding machine and the die. The main types are rubber injection molding, plastic injection molding and molding injection molding. Rubber injection molding is a production method in which rubber is directly injected from a cylinder into a mold for vulcanization. The rubber injection molding has the advantages that: although the method is an intermittent operation, the forming period is short, the production efficiency is high, the raw material preparation process is omitted, the labor intensity is low, and the product quality is excellent. Plastic injection molding is a method of producing plastic products by injecting molten plastic into a plastic product mold under pressure, and cooling and molding the plastic product to obtain various plastic parts. There are mechanical injection molding machines that are specifically used for injection molding. The plastic most commonly used today is polystyrene.
