Blow molding is a manufacturing process used to form empty plastic parts, typically substantial ones like bottles, tanks, and vehicle elements. The system involves inflating a preform – a small, molten plastic tube – with forced air inside a cavity. This pressure pushes the plastic against the sides of the cavity, assuming its desired form. Once the plastic has solidified and settled, the item is extracted and the cavity is released for the next cycle, facilitating a comparatively fast and cost-effective fabrication rate.
