Blow molding is a fabrication process used to produce hollow plastic items, typically large ones like bottles, drums, and car parts. The system involves inflating a preform – a small, warm plastic cylinder – with forced air within a mold. This expansion presses the plastic against the sides of the cavity, assuming its desired form. Once the plastic has cooled and fixed, the item is extracted and the cavity is opened for the subsequent cycle, making a generally efficient and affordable fabrication speed.
