What Is The Reason That Dies Used For Striking Gold Coins Or Medals Go Through Vacuum Hardening Processes?
The technique of vacuum hardening is utilized in the manufacturing of gold coins or medals. It involves heating the dies at high temperatures and then exposed to controlled conditions within the vacuum. Here is a brief overview of the process of vacuum hardening.
When creating dies to be used in striking coins or other medals, it's essential that they are free of residues or contamination.
Injecting Vacuum Furnace
The dies may be put into a vacuum oven, which causes a vacuum to be created in the heat-treatment area.
Evacuation Air-
The vacuum oven removes all air from the room creating an environment free of oxygen as well as other gases. This helps prevent oxidation and guarantees an even heat treatment.
Heating Phase
The furnace will be heated up to the required temperature to harden the dies. Temperature ranges vary depending on the materials used and the process of hardening.
Soaking in high temperature
The material is allowed to achieve the desired hardness, as well as the metallurgical structure.
Quenching (or cooling)
After the soaking, dies have to be cooled quickly by specialized methods. The quick cooling assists the metal to achieve the required hardness.
Tempering (Optional)-
In certain instances, a tempering step is carried out following the stage of hardening. Die dies are heated at a lower temperature in order to lessen internal stress and improve durability, while preserving hardness.
Quality Control and Inspection-
Hardened dies must pass thorough quality inspections and control to ensure they achieve the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
Die dies are then later subjected to further treatment including coating or polishing, prior to being used to create the coins or medals.
The process of vacuum hardening enhances the durability and wear resistance and the life span of dies, which are employed to make coins or medals. In creating a controlled, safe environment free of atmospheric pollutants, this process ensures constant and reliable hardening dies, thereby enhancing the quality and longevity of the products that are minted.
