Blow molding is a manufacturing process used to produce void plastic components, typically bulky ones like containers, drums, and vehicle elements. The system involves expanding a preform – a small, molten plastic cylinder – with forced air inside a die. This expansion pushes the plastic against the sides of the die, creating its final form. Once the plastic has hardened and fixed, the component is removed and the cavity is opened for the subsequent cycle, allowing a generally fast and affordable production speed.
Innovations in Blow Process
