Blow molding is a fabrication technique used to form hollow plastic parts, typically large ones like containers, tanks, and vehicle elements. The process involves expanding a preform – a small, warm plastic tube – with high-pressure air within a mold. This inflation presses the plastic against the sides of the mold, creating its final shape. Once the plastic has hardened and fixed, the part is removed and the cavity is unlocked for the following cycle, allowing a relatively quick and economical manufacturing output.
