Basic information of injection molding

injection molding
The injection molding process can be roughly divided into the following six stages:
Mold closing, glue injection, pressure maintaining, cooling, mold opening and product removal.
If the above process is repeated, products can be produced periodically in batches. The molding of thermosetting plastics and rubber also includes the same process, but the temperature of the material barrel is lower than that of thermoplastic plastics, and the injection pressure is higher. The mold is heated. After the injection of materials, it needs to go through the curing or curing process in the mold, and then take advantage of the heat to release the film.
Nowadays, the trend of processing technology is developing towards high-tech. These technologies include micro injection molding, high filling composite injection molding, water assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, etc.
