Blow molding is a fabrication process used to create hollow plastic parts, typically large ones like bottles, drums, and car components. The system involves inflating a preform – a small, heated plastic tube – with forced air within a cavity. This pressure pushes the plastic against the surfaces of the cavity, creating its final form. Once the plastic has cooled and fixed, the component is ejected and the mold is released for the following cycle, facilitating a relatively quick and economical manufacturing output.
