6 Stages Of Injection Molding Process

Mold closing, glue shooting, pressure holding, cooling, mold opening, product removal.
The above process is repeated, and the products can be produced periodically in batches. The molding of thermosetting plastics and rubber also includes the same process, but the barrel temperature is lower than that of thermoplastics, the injection pressure is higher, the mold is heated, and the material needs to be cured or vulcanized in the mold after injection, and then the film is removed while hot.
Nowadays, the trend of processing technology is developing in the direction of high-tech, these technologies include: micro-injection molding, high-fill composite injection molding, water-assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, etc.
