Blow molding is a manufacturing technique used to form empty plastic items, typically bulky ones like bottles, drums, and car parts. The procedure involves inflating a preform – a small, molten plastic cylinder – with high-pressure air into a cavity. This expansion presses the plastic against the surfaces of the cavity, assuming its final configuration. Once the plastic has solidified and settled, the part is extracted and the mold is released for the following cycle, making a generally efficient and affordable production rate.
