Punching and forming require tough tools and dies. PEM Technologies’ Precision Electrochemical Machining is a great match because it is a non-contact metal forming process which generates complex macro- and micro-structures in extremely hard metals. Leaving behind no burrs, thermal or mechanical stresses, microcracks, white layers or electrode wear, PEM can produce parts in any quantity — from prototypes to mass production.

Typical Applications:

• Punch dies
• Cutting dies
• Heading dies
• Mold cavities
• Wire drawing dies
• Cold forming dies
• Forming tools
• Innovative tool designs
• Cooling passages
• Mandrels

Four separate punch tools for EDM now produced as one part with PEM

Once produced as four separate tools via wire EDM, the star- and sun-shaped features shown here are now part of a single precision punch produced with PEM. Note the undercut around the entire geometry.
