The Difference Between Blister,Injection and Blow Molding

- Apr 13, 2019-

Blow molding: a tubular plastic parison obtained by extrusion of nylon, placed in a split mold while hot, compressed air in the parison immediately after closing the mold, inflating the plastic parison and adhering to the inner wall of the mold, cooling off Mold, a variety of hollow products are obtained. The main products are: nylon casing film, bottles, cans, nylon tubes, etc.

Injection molding: molding is mostly used for thermoplastics. It is similar to extrusion molding, except that the molten plastic enters through the nozzle in a closed mold, and is solidified in the mold to obtain a product. More production of small boxes, daily necessities. Shaped parts, etc. It can also be used for lively plastic processing.

Blister: The main principle of blister processing technology is to heat and soften the flat plastic hard sheet. It is vacuum-adsorbed on the surface of the mold and cooled to form, saving original and auxiliary materials, light weight and convenient transportation.
