Production process

In the design and production of plastic containers, attention must be paid to the following problems: bloating, elongation, vertical load strength, rigidity of the container, supporting surface, cover thread, shape and outer surface, forming, temperature and pressure, etc. in order to ensure the mechanical properties of plastic containers, formability, mold structure and processing rationality and Container usage conditions. The technological process is: mixing, screw extrusion, mold closing, blow molding, die opening, cooling, trimming and testing.
