Blow molding is a production process used to create Blow Molding hollow plastic items, typically bulky ones like receptacles, barrels, and car parts. The process involves expanding a preform – a small, heated plastic shape – with forced air within a mold. This pressure presses the plastic against the walls of the die, assuming its ultimate shape. Once the plastic has hardened and stabilized, the item is extracted and the mold is opened for the subsequent cycle, making a comparatively quick and affordable manufacturing speed.
