Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression method and die casting method. Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make various shapes of plastic products from thermoplastics or thermosets. Injection molding is achieved through injection molding machines and molds.
1. Rubber injection molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into the model to vulcanize. 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 eliminated, the labor intensity is small, and the product quality is excellent.
2. Plastic injection: Plastic injection is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, and the plastic parts are cooled and molded to obtain various plastic parts. There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastic is polystyrene.
The resulting shape is often a finished product, and no other processing is required before installation or use as a final product. Many details, such as protrusions, ribs, and threads, can be molded in one step of injection molding.
