Blow molding is a fabrication method used to form void plastic components, typically bulky ones like containers, barrels, and vehicle elements. The system involves distending a preform – a small, warm plastic shape – with forced air inside a mold. This inflation presses the plastic against the walls of the cavity, creating its desired form. Once the plastic has cooled and settled, the item is removed and the mold is released for the following cycle, allowing a comparatively quick and affordable manufacturing speed.
