Blow molding is a fabrication technique used to create empty plastic parts, typically substantial ones like containers, tanks, and car elements. The procedure involves expanding a preform – a small, warm plastic cylinder – with compressed air inside a die. This inflation forces the plastic against the surfaces of the mold, taking its final configuration. Once the plastic has solidified and stabilized, the component is ejected and the cavity is unlocked for the next cycle, allowing a comparatively fast and economical fabrication rate.
