Blistering: Plastic processing technology, the main principle is to heat and soften flat plastic hard sheets, use vacuum adsorption on the surface of the mold, cool and form, saving raw and auxiliary materials, lightweight, and convenient transportation.

Blow molding: The tubular plastic preform obtained by extrusion of nylon is placed in a split mold while it is hot. After the mold is closed, air is immediately compressed in the preform to expand the plastic preform and tightly adhere to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. The main products are: nylon casing film, bottles, cans, nylon tubes, etc.

Injection molding: Molding is commonly used for thermoplastic materials. It is similar to extrusion molding, except that the molten plastic enters the closed mold through a nozzle and solidifies into the mold to form the product. Produce more small packaging boxes, daily necessities, special-shaped parts, etc. It can also be used for lively plastic processing.
