Blow molding is a production method used to form hollow plastic items, typically bulky ones like receptacles, drums, and vehicle components. The procedure involves distending 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, assuming its desired form. Once the plastic has hardened and fixed, the component is removed and the cavity is released for the following cycle, making a relatively fast and affordable fabrication output.
