Injection molded parts refer to all kinds of injection molded products produced by injection molding machines, including various packages, parts, etc., which are mainly made of polyethylene or polypropylene and added with a variety of organic solvents. The selection of plastic parts mainly depends on the type and initial form of the plastic and the shape and size of the product. Injection molded parts are generally made by molding, transfer molding, injection molding, lamination Molding and hot forming are used to form plastics on a flat surface. The above methods can be used for rubber processing. In addition, there are casting with liquid monomers or polymers as raw materials. Among these methods, extrusion and injection molding are the most commonly used and the most basic molding methods.
Injection types mainly include:
1. Rubber injection molding(https://www.chapmanmaker.com/lsr-mold-ding/): rubber injection molding is a production method of injecting rubber directly from the 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, the embryo preparation process is canceled, the labor intensity is small, and the product quality is excellent.
2. Plastic injection molding: plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, cooled and molded to obtain various plastic parts. There are mechanical injection molding machines specially used for injection molding. At present, 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 molded in one step of injection molding.
