Blow molding is a production method used to form void plastic items, typically substantial ones like containers, barrels, and automotive parts. The system involves distending a preform – a small, warm plastic shape – with high-pressure air within a cavity. This expansion pushes the plastic against the walls of the mold, taking its desired form. Once the plastic has solidified and fixed, the component is extracted and the mold is unlocked for the next cycle, allowing a generally efficient and cost-effective production rate.
