Why Does A Gold Coin Or Medal Dies Go Through Vacuum Hardening?
The hardening by vacuum of dies used to strike gold medals and coins is achieved by subjecting them to extremely high temperatures under controlled conditions in a vacuum chamber. Here's an outline of the vacuum hardening procedure used for die preparation and Cleaning-
It is vital that dies used for striking medals and coins are completely free of any contamination and residues.
Loading Vacuum Furnace
The dies are put into the vacuum chamber.
Evacuation of Aircraft
The vacuum oven removes all air from the chamber creating an environment free of oxygen and other gases. This helps prevent oxidation and guarantees an even heat treatment.
Heating Phase
The furnace then gets heated up to the temperature desired for the hardening of dies. The temperature range is determined by the type of material and the method of hardening.
Soaking at High temperatures
The dies are kept at the elevated temperature for a precise duration, allowing the material to attain and maintain the desired hardness and metallurgical structure.
Cooling or Quenching
Using specialized methods that allow dies to be quickly cooled down or quenched after the soak process. This process of rapid cooling helps keep the desired strength and hardness of the steel.
Tempering Options
In some instances, the process of hardening can be followed by a tempering process. Tempering involves heating the dies to a lower temperature, which helps alleviate internal stress and increase toughness while maintaining hardness.
Quality Control and Inspection
To ensure they meet the hardness and strength requirements Die dies that have been hardened go through an extensive inspection and quality test.
Post-Treatment Handling-
The dies are then coated or polished and used to strike coins or medals.
The process of vacuum hardening enhances the strength, durability as well as the wear resistance and life span of the dies used to create gold medals or coins. In ensuring a safe and free of contaminants it provides a consistent and reliable way to make the dies harder.
