Blow molding is a production method used to create hollow plastic parts, typically bulky ones like containers, barrels, and vehicle components. The system involves distending a preform – a small, molten plastic tube – with forced air into a die. This inflation pushes the plastic against the surfaces of the mold, assuming its final shape. Once the plastic has solidified and settled, the item is removed and the mold is released for the subsequent cycle, facilitating a relatively fast and affordable manufacturing speed.
