Blow molding is a manufacturing method used to form empty plastic components, typically large ones like containers, barrels, and vehicle parts. The process involves inflating a preform – a small, heated plastic tube – with compressed air inside a cavity. This expansion pushes the plastic against the walls of the mold, assuming its ultimate shape. Once the plastic has hardened and settled, the part is removed and the cavity is unlocked for the subsequent cycle, facilitating a generally efficient and economical production rate.
