Why Do Gold Coin Or Medal Dies Undergo The Process Of Hardening By Vacuum?
The vacuum hardening process used for dies in striking gold medals or coins involves making the dies subject to high temperatures and controlled environments in a vacuum furnace. This is a brief description of the process of vacuum hardening.
When preparing dies to be used for striking metals or coins, it's crucial that they are clean of contamination or residues.
Moving into Vacuum Furnace-
The dies go into an environment chamber that is vacuum.
Evacuation Air
The vacuum oven eliminates any air in the room and creates a safe environment without oxygen and other gases. This guarantees uniform heating and prevents the oxidation process from occurring.
Heating Phase
The furnace is then heated to a certain temperature to harden the dies. The range of temperatures is determined by the particular material and the processes for hardening.
Bathing in high temperatures
The material is allowed to attain the desired hardness and the metallurgical structure.
Cooling or cooling down
After the soaking process it is possible to quickly cooled with the help of specialized techniques. The speedy cooling allows the metal achieve the required hardness.
Tempering is an option
In a few cases, a tempering step occurs following the stage of hardening. Tempering is the process of heating the dies at a lower temperature in order to relieve internal stresses and improve toughness while maintaining their hardness.
Quality Control and Inspection
The hardened dies undergo thorough quality checks and inspections to ensure that they meet the standards for toughness, hardness and tolerances to dimensional dimensions.
Post-Treatment Handling-
The dies, following the process of vacuum-hardening has been completed, may be further processed, such as polishing and coating before they are used in strike of coins or medals processes.
The process of vacuum hardening increases the strength, wear resistance, and lifespan of the dies used to create gold medals or coins. This process creates a controlled atmosphere free of atmospheric contaminants to ensure a consistent and reliable process of hardening. This also enhances the quality of the minted product.
