Blow molding is a production process used to form empty plastic items, typically bulky ones like receptacles, barrels, and car elements. The procedure involves distending a preform – a small, molten plastic tube – with high-pressure air within a die. This expansion pushes the plastic against the surfaces of the die, assuming its final form. Once the plastic has hardened and settled, the part is extracted and the die is opened for the next cycle, facilitating a comparatively quick and affordable fabrication output.
