The respective characteristics of the two types of injection molding processing
Injection molding is a highly technical and practical industry. It requires the use of plastic raw materials, color powder, sprue material, molds, injection molding machines, peripheral equipment, tooling fixtures, sprays, various auxiliary materials and packaging materials, etc. There are two types of injection molding: rubber injection molding and plastic injection molding. No matter which type of injection molding it is, it has its own advantages. Let's take a look at these two types of injection molding.
Rubber injection molding: Rubber injection molding is a production method in which rubber compound is directly injected from the barrel into the mold for vulcanization. The advantages of rubber injection molding are as follows: although it is an intermittent operation, the molding cycle is short, the production efficiency is high, the preform preparation process is eliminated, the labor intensity is low, and the product quality is excellent.
2. Plastic injection molding: Plastic injection molding is a method for plastic products. Molten plastic is injected into a plastic product mold under pressure and then cooled to form various plastic parts as desired. There are specialized mechanical injection molding machines for injection molding. The most commonly used plastic at present is polystyrene. The resulting shape is often the final 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.
