Blow molding is a manufacturing method used to form void plastic components, typically large ones like containers, drums, and vehicle parts. The process involves distending a preform – a small, warm plastic tube – with high-pressure air inside a die. This expansion forces the plastic against the sides of the die, taking its final shape. Once the plastic has solidified and stabilized, the item is removed and the die is released for the subsequent cycle, allowing a relatively fast and affordable fabrication rate.
