Tool Type: Powder Metal Compaction Punch
Work Material: FC-0208 Steel metal powder
Original Tooling Material: CPM® 3V® tool steel hardened to RC 58-60
Problem: The required high density of the compacted part combined with the high compaction forces required to form the part, would deform the bevel and face detail to the CPM® 3V® punch. The deformation of the face detail and bevel would require that the punch would be redressed after 20,000 parts were formed. More than 4 hours of downtime caused lost production.
Solution: Upgrade to Z-Wear PM® tool steel hardened to RC 62-64.
Results: Due to the higher toughness and higher hardness of the Z-Wear PM® at RC 62-64, the face detail and bevel resisted deformation. The face detail held intact for 55,000 parts before wear of the leading edge required the punch to be redressed.
