Why Do Dies Used To Strike Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
Vacuum hardening is a procedure that involves exposing dies to extreme temperatures and a controlled environment in furnaces. This is a brief overview of how to make dies harder by vacuum.
Diets for striking medals and coins are cleaned and free of any contaminants.
Moving into Vacuum Furnace
Die dies are placed in a vacuum chamber, which is an specialized heat-treating room that can create vacuum.
Evacuation of Air
The vacuum chamber is made by eliminating air from the chamber, and then creating an atmosphere that is completely free of oxygen. This stops oxidation, and provides uniform heating.
Heating Phase
The furnace has to be heated to a temperature required for the dies to be hardened. The temperature range varies based on the material and process of hardening.
Soaking with High Temperatures
The dies are held at the elevated temperature for a specific time which allows the material to achieve and maintain the desired hardness and metallurgical structure.
Quenching (or Cooling)
After the soaking phase after which the dies are quickly cooled with the help of specialized techniques. The fast cooling process locks in the required toughness and hardness of the steel.
Tempering Options
In some instances the tempering process is a part of the process of hardening. The dies are reheated to a lower heat to ease internal stress and increase durability, while preserving hardness.
Quality Control Inspection
To ensure they meet the standards for hardness and strength Die dies that have been hardened go through an exhaustive inspection and quality check.
Post-Treatment Handling-
When the process of hardening by vacuum is complete Die dies are then subject to additional processes such as polishing or coating before they are utilized in the coin or medal striking process.
The process of vacuum hardening increases the durability of dies and wear resistance, and also the life span of the dies used to create gold or silver coins and medals. Through ensuring a controlled and clean environment, this process provides an exact and reliable method to harden the dies.
