Ultimate Guide of PET bottle blow moulder process Principle of the blow molding process: The blow molding process includes three basic steps: preform moulding, blow moulding and bottle cooling. First, process the plastic into a preform (injection or extrusion) and place the high-temperature preform in a blow mould. Inject compressed air into the preform to inflate it until it is close to the cavity wall, and maintain the blowing pressure until the bottle cools. After finalizing the shape, the hollow bottle can be obtained when the mould is opened. https://ibottling.com/pet-bottle-blow-moulder-process/
