Detroit Flame Hardening - Dies & Molds
Stamping, blanking, forming, shearing, cast gray iron, ductile iron, carbon steels and alloy steels.
The initial cost of a die is very high, and wear on the die is usually confined to small areas.
Even the most intricate shapes can be flame hardened
- Flame hardening of dies and molds reduces wear and increases die life.
- Large automotive dies provide ideal examples of the proper application of flame hardening and can be handled as readily as small ones.
- Smaller dies may require hardening of "shut-off" or "runner" areas only. Instead of buying new dies, flame hardening allows the reworking of old dies by making shape modifications and re-flame hardening
- Dies can be finished and tried out before they are finally flame hardened for production runs.
- For molds, the flame hardened areas are usually adjacent to the die working areas, so there is a minimum of heat exposure, which eliminates distortion.
