What Is The Reason That Dies Used For Striking Gold Medals Or Coins Undergo Vacuum Hardening Processes?
The vacuum hardening method is employed in the making of gold medals or coins. The process involves heating the dies at high temperatures, and exposed to controlled conditions inside a vacuum. This article provides a quick overview of the vacuum-hardening process.
To make dies that will be used to strike the coins or medals, they must be free of any contaminants or residues.
Injecting Vacuum Furnace
Die dies are then put in a specially designed heat-treating chamber which can generate a vacuum.
Evacuation Air-
The vacuum furnace removes the air inside the chamber to create an environment controlled by vacuum that is free of any oxygen or other gasses. This eliminates oxidation, and ensures uniform heating.
Heating Phase-
The furnace is then heated to the desired temperature for hardening dies. The range of temperatures is determined by the particular material and the hardening process.
Bathing at high temperatures-
The dies stay at high temperatures for a specific duration, allowing the material the reach the hardness that is desired and to maintain metallurgical structures.
Quenching (or Cooling)
After soaking, the dies are rapidly cooled or quenched using specialized methods. This rapid cooling process helps lock in the desired hardness and strength in the material.
Tempering is an option
In some situations the process of tempering can occur as a result of hardening. Tempering is the process of heating dies up until they reach a temperature that is lower to relieve stress while maintaining their toughness.
Quality Control and Inspection
Hardened dies are subjected to thorough quality inspections and checks to ensure they meet standards for strength, hardness and tolerances for dimensional dimensions.
Post-Treatment Handling-
After the hardening process, dies can be polished or coated prior to the time they are used in the coin or the metal striking process.
Vacuum hardening increases the longevity endurance, durability and wear resistance of the dies that are used to strike gold coins or medals. This process produces a controlled and safe environment that is free of contaminants from the atmosphere to ensure a consistent and reliable process of hardening. It also improves the quality of the final product.
