Blow molding is a fabrication technique used to create void plastic parts, typically bulky ones like containers, barrels, and automotive elements. The procedure involves inflating a preform – a small, molten plastic tube – with forced air inside a mold. This expansion pushes the plastic against the sides of the mold, assuming its final shape. Once the plastic has solidified and stabilized, the component is removed and the die is opened for the subsequent cycle, making a generally efficient and affordable fabrication speed.
