Blow molding is a production technique used to produce void plastic components, typically bulky ones like containers, tanks, and automotive parts. The process involves distending a preform – a small, heated plastic cylinder – with forced air inside a die. This pressure pushes the plastic against the surfaces of the cavity, creating its ultimate form. Once the plastic has solidified and settled, the item is extracted and the cavity is opened for the subsequent cycle, making a comparatively efficient and economical Blow Molding production output.
