Blow molding is a manufacturing method used to form empty plastic parts, typically substantial ones like bottles, barrels, and vehicle elements. The system involves inflating a preform – a small, heated plastic shape – with high-pressure air into a mold. This pressure pushes the plastic against the walls of the die, taking its desired shape. Once the plastic has hardened and settled, the part is extracted and the die is opened for the following cycle, allowing a generally quick and economical fabrication rate.
