Blow molding is a production process used to form empty plastic items, typically substantial ones like bottles, barrels, and car parts. The system involves expanding a preform – a small, warm plastic shape – with forced air within a mold. This pressure presses the plastic against the sides of the cavity, taking its ultimate form. Once the plastic has solidified and stabilized, the component is removed and the die is unlocked for the following cycle, allowing a relatively fast and economical manufacturing output.
Innovations in Shaping Technique
