Blow molding is a manufacturing method used to create void plastic items, typically large ones like receptacles, tanks, and automotive components. The system involves expanding a preform – a small, molten plastic tube – with forced air into a cavity. This inflation forces the plastic against the walls of the mold, creating its ultimate configuration. Once the plastic has hardened and fixed, the component is removed and the cavity is released for the following cycle, allowing a generally quick and economical fabrication speed.
Innovations in Shaping Process
