Blow molding is a production method used to create hollow plastic components, typically bulky ones like receptacles, tanks, and automotive elements. The process involves expanding a preform – a small, heated plastic cylinder – with compressed air within a cavity. This pressure pushes the plastic against the sides of the die, creating its final shape. Once the plastic has cooled and fixed, the item is removed and the mold is released for the next cycle, facilitating a generally fast and cost-effective manufacturing rate.
Advances in Moulding Technology
