Blow molding is a fabrication method used to form hollow plastic items, typically substantial ones like bottles, drums, and car parts. The procedure involves inflating a preform – a small, molten plastic tube – with forced air into a mold. This inflation forces the plastic against the surfaces of the die, creating its final form. Once the plastic has cooled and settled, the item is ejected and the cavity is opened for the following cycle, making a generally quick and affordable fabrication rate.
