The injection molding process is a kind of plastic molding process, which is mainly a process of turning raw materials into products through injection molding machines and injection molds. The process parameters of injection molding mainly include injection temperature, injection pressure, holding pressure, cooling time, clamping force, etc. By adjusting these parameters, the size and appearance of the product can meet the requirements. Relatively speaking, the injection molding process mold is relatively expensive, the product price is very cheap, and the market is more transparent. It is mainly suitable for the production of relatively small-sized products. The monthly output is very large. The molds and products are of very high precision. Common films are used in various fields.
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.
Main types:
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 then cooled and molded to obtain various plastic parts. There are mechanical injection molding machines dedicated to 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 protrusions, ribs, and threads, can be formed in one step of injection molding.
