Blow molding is a production process used to produce empty plastic items, typically substantial ones like receptacles, barrels, and automotive components. The process involves inflating a preform – a small, molten plastic cylinder – with high-pressure air within a mold. This expansion forces the plastic against the surfaces of the cavity, assuming its desired form. Once the plastic has solidified and settled, the component is extracted and the cavity is opened for the next cycle, facilitating a generally efficient and cost-effective production rate.
