Blow molding is a manufacturing process used to produce void plastic components, typically large ones like bottles, drums, and automotive components. The procedure involves distending a preform – a small, heated plastic tube – with forced air inside a mold. This expansion forces the plastic against the sides of the mold, creating its desired configuration. Once the plastic has cooled and fixed, the part is removed and the cavity is released for the subsequent cycle, facilitating a comparatively fast and affordable fabrication rate.
