Blow molding is a production technique used to produce void plastic components, typically bulky ones like receptacles, barrels, and automotive parts. The procedure involves expanding a preform – a small, molten plastic cylinder – with compressed air inside a mold. This inflation forces the plastic against the sides of the die, assuming its ultimate shape. Once the plastic has hardened and fixed, the item is ejected and the die is released for the subsequent cycle, making a comparatively fast and affordable production output.
