Injecting Vacuum Furnace-
The dies can be placed into a vacuum oven, which causes a vacuum to be created in the heat-treating area.
Evacuation from Air
The vacuum oven eliminates all air from the room making it a clean space free of oxygen as well as other gases. This prevents burning while ensuring the same heating.
Heating Phase
The furnace has to be heated to the appropriate temperature required for the dies to be hardened. The range of temperatures is determined by the material used and the processes for hardening.
Soaking at high temperatures-
The dies remain at the high temperatures for a specific time, which allows the material to reach the level of hardness desired and also maintain the metallurgical structure.
Quenching and Cooling
After the soaking phase it is possible to rapidly cooled using specialized techniques. The rapid cooling process locks in the desired toughness and hardness of the material.
Tempering (Optional).
In certain cases the tempering process is a part of the hardening process. The dies are heated up at a lower temperature in order to ease internal stress and improve the toughness of the die, while preserving its hardness.
Quality Control and Inspection
The molds that are hardened are inspected and tested to ensure that the dies satisfy all the specifications.
Post-Treatment Handling-
The dies, after the vacuum-hardening process is completed, can be further processed using polishing and coating, before they are used in the strike of coins or medals processes.
The vacuum hardening method increases die durability and wear resistance as well as the longevity of the dies used for striking silver or gold coins and medals. In ensuring a safe and clean environment the process offers a consistent and reliable way to make the dies harder.
