Blow molding is a manufacturing technique used to produce empty plastic items, typically large ones like containers, drums, and vehicle components. The system involves expanding a Blow Molding preform – a small, warm plastic shape – with forced air inside a cavity. This inflation presses the plastic against the walls of the die, taking its ultimate shape. Once the plastic has cooled and stabilized, the component is ejected and the die is opened for the following cycle, facilitating a generally fast and affordable production rate.
