What is injection molding?

What is injection molding? Many friends outside the industry may not be very clear, so today I will introduce it to you. Injection molding is a method of industrial product production molding. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding, compression molding, and die-casting.

The main types of injection molding include: rubber injection molding, plastic injection molding, and molding injection molding

1. Rubber injection molding: Rubber injection molding is a production method that directly injects rubber material from the machine 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, and the embryo preparation process is canceled. The labor intensity is low, and the product quality is excellent.

2. Injection molding: The resulting shape is often the finished product, and no further 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.

3. Plastic injection molding: Plastic injection molding is a method of plastic products that uses pressure to inject molten plastic into plastic product molds, and then cools them to form various desired plastic parts. There are mechanical injection molding machines specifically designed for injection molding. The commonly used plastics currently include polyethylene, polypropylene, ABS, PA, polystyrene, etc.
