Blow molding is a production process used to create empty plastic components, typically bulky ones like containers, drums, and automotive parts. The process involves inflating a preform – a small, warm plastic tube – with forced air inside a die. This pressure forces the plastic against the surfaces of the die, taking its final configuration. Once the plastic has solidified and settled, the part is ejected and the mold is released for the following cycle, allowing a relatively fast and affordable fabrication output.
