Basic Information Of Plastic Injection Molding

The injection molding process can be roughly divided into the following 6 stages:

Mold clamping, injection, pressure keeping, cooling, mold opening, and product removal.

By repeating the above process, 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, and the injection pressure is higher. The mold is heated. After the material is injected, it needs to undergo a curing or vulcanization process in the mold, and then release the film while it is hot .

Nowadays, the trend of processing technology is developing in the direction of high and new technology. These technologies include: micro injection molding, high filling compound injection molding, water-assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, etc.
