Trimming, piercing and blanking

Tools for trimming, piercing and blanking of ferrous and non-ferrous alloys need to be able to shear through the cross-section of the coil and retract through the sheared edges with limited to no lubrication at the contact surfaces. The resulting abrasive and adhesive wear can severely decrease tool life and increase scrap rates, especially in applications where AHSS and aluminum alloys are involved. In these applications, spring-back is an increasing concern. Ionbond PVD and PACVD coatings improve tool life and reduce scrap rates by providing the necessary resistance to wear and galling without affecting the tool tolerances.
