Blow molding is a fabrication process used to create empty plastic items, typically large ones like containers, tanks, and automotive elements. The system involves inflating a preform – a small, heated plastic tube – with compressed air inside a die. This expansion pushes the plastic against the sides of the die, taking its ultimate configuration. Once the plastic has cooled and fixed, the part is removed and the cavity is opened for the following cycle, facilitating a generally quick and economical fabrication speed.
