Blow molding is a fabrication process used to create hollow plastic components, typically bulky ones like bottles, drums, and car components. The process involves expanding a preform – a small, warm plastic tube – with forced air into a cavity. This pressure presses the plastic against the sides of the mold, taking its ultimate shape. Once the plastic has cooled and fixed, the part is extracted and the die is unlocked for the next cycle, facilitating a comparatively fast and affordable fabrication speed.
