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.

Applications:

• Plastic mold dies
• Metal stamping, blanking, forming, and shearing dies

Suitable materials:

• Alloy steels
• Plain carbon steels
• Ductile iron
• Cast iron
• Stainless steel
