The choices are growing in single-stage systems for PET blow molding

Manufacturers of industrial equipment are introducing new single-stage machines for the blow molding of polyethylene terephthalate (PET) bottles. Single-stage systems combine the injection unit and the blow molder so that the bottle preform does not have to be reheated on a stretch-blow molding system for processing. Single-stage machines are used more often than two-stage systems in the manufacture of wide-mouth containers, but they are unable to provide enough strength for carbonated-beverage bottles.
