Pet Blow Moulding Machine

In PET blow molding, Reheat Stretch Blow Machines are the second part of the process of bottle manufacturing. They load completely cooled down preforms onto rotating mandrels, heat them up to blowing temperature through an oven section, allow a short period for equalization and then stretch and blow them into bottles. 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.20-Apr-2016
