The furnace is then heated to the temperature desired for hardening dies. Temperature ranges vary depending on the materials used and the processing for hardening.
Drinking at high temperatures
The dies are kept at an elevated temperature for a specified time which allows the material to reach and retain the desired hardness as well as metallurgical structure.
Quenching or Cooling-
After the soaking process after which the dies are quickly cooled by using special techniques. This fast cooling process assists in locking the desired hardness of the material.
Tempering Options
In some instances, tempering can follow the process of hardening. Tempering is the process of heating dies up to a lower temperature in order to ease stress and maintain their toughness.
Quality Control Inspection
Hardened dies must pass thorough quality control and inspections to attain the desired toughness, hardness, or tolerances.
