Why Do Dies Used To Make Gold Medals And Coins Undergo Vacuum-Hardening Processes
To make dies harder to make gold coins or medals, they are subjected to controlled temperatures in the vacuum oven. Here's a quick overview of how to make dies harder by vacuum.
It is crucial that dies used for striking medals and coins are completely free of any contamination and residues.
Loading into Vacuum Furnace
The dies are put into a vacuum-environment chamber.
Evacuation of Air-
Vacuum furnaces eliminate air from chambers, resulting in an oxygen-free environment. This is to prevent burning and also to guarantee uniform heat treatments.
Heating Phase
The furnace then gets heated up to the desired temperature for the hardening of dies. The range of temperatures is determined by the material being used and the hardening procedure.
Soaking with High Temperatures
The material is allowed to reach the desired hardness and the metallurgical structures are created.
Quenching or Cooling
After the soaking period and the dies are then cooled or quenched using specialized methods. This process of rapid cooling helps keep the desired hardness and strength in the material.
Tempering (Optional).
In certain cases, hardening is then followed by a tempering process. Tempering is the process of reheating dies at a low temperature in order to release internal tensions and increase durability.
Quality Control and Inspection
To make sure they meet the specifications for strength and hardness the dies that are hardened undergo a thorough inspection and quality control.
Post-Treatment Handling-
The dies, following the process of vacuum-hardening has been completed, may be further processed using polishing and coating prior to when they are used in the coin striking or medal striking processes.
The process of vacuum hardening increases the durability of dies and wear resistance, as well as the lifespan of the dies used for striking gold or silver coins and medals. This procedure creates a controlled environment free of airborne contaminants to ensure consistent and reliable hardening. This also enhances the overall quality of the minted product.
