Blow molding is a manufacturing process used to form empty plastic parts, typically large ones like containers, barrels, and vehicle elements. The procedure involves distending a preform – a small, heated plastic shape – with high-pressure air within a die. This expansion pushes the plastic against the surfaces of the mold, creating its desired shape. Once the plastic has solidified and fixed, the part is removed and the cavity is released for the subsequent cycle, allowing a comparatively quick and affordable production rate.
