Pet Stretch Blow Moulding Machine

Stretch blow molding is one type of blow molding that allows the preformed products – in this example that being bottles – to be manufactured into high-quality bottles with high clarity – and the full scope of stretch blow molding allows for an extensive and diverse number of uses. 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.
