Using Cold Air To Cool Coffee Creamer Closures

A customer is using a 48 cavity mold to manufacture closures for a coffee creamer bottle. The after mold process includes orienting and closing the closure. Heat still present from the molding process causes the hinge to malfunction, especially if the cavity in the mold is worn. Typical reject rate is 4%. They found that if they could cool the hinge, the closure hinge works well. They are using a Model 3230 Vortex Tube to purge the feeder bowl with cold air to get the parts cool before they are oriented and closed. They are increasing production by 4%.
