Blow molding is a manufacturing process used to form hollow plastic components, typically substantial ones like receptacles, barrels, and vehicle components. The procedure involves distending a preform – a small, warm plastic cylinder – with high-pressure air into a die. This inflation forces the plastic against the surfaces of the die, assuming its ultimate form. Once the plastic has hardened and settled, the component is ejected and the die is unlocked for the subsequent cycle, making a comparatively fast and economical manufacturing speed.
