Pet Blow Machine

In the early developments, performs were made by continuously extruding a PET tube. To make these prefroms, a perform manufacturing machine that took a continuously extruded PET tube, heated and closed one end, and then heated the other and formed a thread finish by blow moulding.The PET bottle blow moulding process works by reheating a pre-moulded PET preform which is then automatically positioned into a mould. High pressure food grade compressed air is then injected into the preform which expands to form the shape of the mould.
