Blow molding is a manufacturing method used to produce void plastic items, typically bulky ones like containers, tanks, and car components. The procedure involves distending a preform – a small, molten plastic tube – with forced air into a mold. This expansion forces the plastic against the sides of the die, assuming its desired shape. Once the plastic has solidified and settled, the item is removed and the mold is released for the subsequent cycle, allowing a generally quick and cost-effective manufacturing rate.
