rotary blow molding machine

Our line of indexing continuous extrusion blow molding machinery combines the advantages of both wheel blow molders and shuttle blow molding machinery, namely high output rates with the advantage of a calibrated water cooled neck finish.


Designed to accommodate multiple parisons, multilayer coextrusion, and in-mold-labeling of containers from 12 oz. to 2.5 gallons, the blow molding machinery offers outstanding quality at excellent output to capital cost ratios. The blow molder has been designed for ultimate flexibility by incorporating standard quick changeover features.
