1. Rubber injection molding: rubber injection molding is a production method in which a gum material is injected directly from the barrel into model sulfurization. The advantages of rubber injection molding are: Little intermittent operation, but short molding cycle, high production efficiency abolishes the blastoid preparation procedure, less labor intensity, and superior product quality.

2. Plastic injection molding: plastic injection molding is a method of plasticware that uses pressure injection of molten plastic into a mold of plasticware which is cooled to yield the desired variety of plastic pieces. There are mechanical injection machines specifically designed to perform injection molding. The plastic most commonly used today is polystyrene.

3. Molding injection molding: the resulting shape tends to be the final product and no longer requires other machining before it is mounted or used as the final product. Many of the fine parts, such as bulges, ribs, threads, can be contoured in a single step injection molding operation.
