Blow molding is a production method used Blow Molding to form hollow plastic parts, typically bulky ones like containers, drums, and car components. The system involves inflating a preform – a small, warm plastic tube – with forced air into a die. This expansion presses the plastic against the sides of the die, taking its desired configuration. Once the plastic has cooled and stabilized, the part is ejected and the die is unlocked for the subsequent cycle, facilitating a relatively efficient and affordable production rate.
