Blow molding is a manufacturing process used to create hollow plastic parts, typically large ones like bottles, drums, and car elements. The procedure involves distending a preform – a small, molten plastic tube – with high-pressure air within a die. This pressure forces the plastic against the walls of the mold, assuming its final configuration. Once the plastic has cooled and settled, the part is removed and the die is released for the next cycle, facilitating a relatively quick and economical fabrication rate.
