Blow molding is a fabrication technique used to produce void plastic parts, typically substantial ones like containers, barrels, and automotive parts. The procedure involves distending a preform – a small, heated plastic cylinder – with forced air inside a mold. This expansion forces the plastic against the surfaces of the mold, creating its final shape. Once the plastic has hardened and stabilized, the item is removed and the mold is released for the following cycle, allowing a relatively fast and economical fabrication rate.
