Blow molding is a manufacturing process used to produce hollow plastic components, typically substantial ones like bottles, tanks, and automotive elements. The procedure involves inflating a preform – a small, heated plastic tube – with high-pressure air inside a cavity. This inflation presses the plastic against the walls of the cavity, creating its desired form. Once the plastic has hardened and settled, the component is removed and the die is unlocked for the subsequent cycle, facilitating a comparatively quick and economical production output.
