Blow molding is a production process used to form empty plastic components, typically bulky ones like receptacles, drums, and car elements. The system involves expanding a preform – a small, heated plastic shape – with high-pressure air into a mold. This expansion presses the plastic against the sides of the cavity, assuming its final shape. Once the plastic has cooled and fixed, the part is ejected and the die is released for the next cycle, facilitating a comparatively efficient and cost-effective manufacturing speed.
