Blow molding is a manufacturing technique used to produce empty plastic items, typically substantial ones like receptacles, barrels, and vehicle components. The procedure involves distending a preform – a small, warm plastic shape – with high-pressure air within a cavity. This inflation forces the plastic against the walls of the cavity, creating its final shape. Once the plastic has cooled and fixed, the part is ejected and the die is released for the following cycle, making a comparatively fast and affordable manufacturing speed.
