Blow molding is a manufacturing technique used to produce void plastic items, typically large ones like bottles, barrels, and automotive components. The process involves expanding a preform – a small, molten plastic shape – with high-pressure air inside a die. This inflation forces the plastic against the surfaces of the die, taking its final configuration. Once the plastic has solidified and settled, the item is extracted and the mold is released for the following cycle, allowing a comparatively quick and affordable manufacturing rate.
