Blow molding is a production process used to produce void plastic items, typically large ones like bottles, barrels, and automotive components. The process involves expanding a preform – a small, warm plastic shape – with high-pressure air within a die. This pressure presses the plastic against the surfaces of the cavity, creating its ultimate configuration. Once the plastic has hardened and fixed, the item is removed and the cavity is unlocked for the subsequent cycle, making a relatively quick and affordable production output.
