Mold Project Teaches Criticality of Design Phase Collab

Mold Project Teaches Criticality of Design Phase Collab
Prestige Mold, Eastman Chemical Company, Mold-Masters (owned by Milacron LLC) and Pres-Tek Plastics joined forces on a project to solve customer challenges with producing small medical device parts made of Tritan™ copolyester with a multi-cavity hot runner mold. I spoke with Eastman's market development manager for medical devices to learn more about the Eastman-Prestige collaboration.


The Pellet Enters the Melt Delivery System
Choosing a hot or cold runner system is a decision for the molder and moldmaker that must balance the processing window with budget and time.

The Hot or Cold Choice
Working through a series of structured questions designed to filter away the many choices in cold and hot runner system design is a great, repeatable place to start.
