Blow molding is a production process used to produce void plastic parts, typically substantial ones like bottles, tanks, and car elements. The procedure involves inflating a preform – a small, molten plastic tube – with high-pressure air within a mold. This pressure presses the plastic against the walls of the cavity, creating its desired configuration. Once the plastic has hardened and fixed, the part is extracted and the mold is unlocked for the subsequent cycle, facilitating a relatively fast and economical production speed.
