Punching & Forming
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.
