Blow molding is a production method used to create hollow plastic items, typically substantial ones like bottles, barrels, and vehicle parts. The procedure involves inflating a preform – a small, warm plastic tube – with high-pressure air into a mold. This inflation forces the plastic against the sides of the mold, creating its final form. Once the plastic has hardened and settled, the part is removed and the cavity is released for the next cycle, allowing a comparatively fast and affordable fabrication speed.
