Blow molding is a production technique used to create void plastic components, typically bulky ones like bottles, tanks, and car elements. The system involves expanding a preform – a small, warm plastic cylinder – with compressed air inside a die. This pressure presses the plastic against the surfaces of the cavity, creating its ultimate shape. Once the plastic has cooled and settled, the part is extracted and the cavity is released for the following cycle, making a relatively fast and economical production speed.
