Blow molding is a fabrication process used to create empty plastic items, typically bulky ones like containers, tanks, and car elements. The procedure involves distending a preform – a small, warm plastic cylinder – with forced air within a cavity. This inflation presses the plastic against the surfaces of the cavity, creating its ultimate form. Once the plastic has hardened and settled, the item is extracted and the cavity is released for the subsequent cycle, allowing a generally quick and affordable manufacturing output.
