Why Does Vacuum Hardening Get Used On Dies That Are Used To Create Gold Coins Or Medals?
Vacuum hardening is a process which involves exposing dies to high temperature and controlled environment in furnaces. Here's a quick overview of how to make dies harder by vacuum.
Dies used for making coins or medals are prepared by making sure they are free of any contaminants or residues.
Loading in Vacuum Furnace
The dies may be put into a vacuum oven, that creates a vacuum within the area of heat treatment.
Evacuation via Airplane
The vacuum furnace eliminates the air in the chamber, creating a controlled vacuum, devoid of oxygen and other gases. This assures uniform heating and stops the oxidation process from occurring.
Heating Phase
The furnace is heated to the appropriate temperature to allow the dies to harden. The range of temperature will be determined by the material type and the process of hardening.
Soaking in high temperatures
The dies are kept at the elevated temperature for a specified time, allowing the material to achieve and maintain the desired hardness and metallurgical structure.
Cooling or Quenching
The dies will be quickly cooled or quenched after soak. The quick cooling assists the metal to achieve the desired hardness.
Tempering Optional
In some situations, a process of tempering can occur as a result of hardening. Tempering involves reheating dies at a low temperature to ease internal tensions and increase the toughness.
Quality Control & Inspection
Hardened dies must pass thorough quality inspections and control to attain the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
Dies, once the vacuum-hardening process has been completed, may be further processed, such as polishing and coating, before they are used in the strike of coins or medals process.
The vacuum-hardening process enhances the durability, resistance to wear, and the life span of dies, which are used for striking medals or coins. By ensuring a controlled and clean environment, this process provides an efficient and consistent method to make the dies harder.
