Blow molding is a manufacturing method used to create empty plastic parts, typically bulky ones like receptacles, tanks, and car parts. The system involves inflating a preform – a small, molten plastic cylinder – with compressed air into a mold. This expansion presses the plastic against the walls of the die, creating its desired configuration. Once the plastic has solidified and fixed, the item is extracted and the die is opened for the next cycle, facilitating a comparatively quick and cost-effective manufacturing rate.
