Blow molding is a production technique used to produce empty plastic components, typically large ones like containers, barrels, and vehicle components. The system involves inflating a preform – a small, warm plastic shape – with compressed air into a die. This inflation presses the plastic against the walls of the mold, taking its final shape. Once the plastic has hardened and fixed, the item is removed and the mold is opened for the next cycle, making a generally fast and cost-effective production speed.
