Why Does A Gold Coin Or Medal Dies Undergo A Process Of Vacuum Hardening?
Vacuum hardening refers to a process that involves exposing dies to extreme temperatures and a controlled environment in a furnace. Here's a quick overview of how to make dies harder by vacuum.
Diets for striking medals and coins are clean and free of any contaminants.
Injecting Vacuum Furnace-
Die dies are kept in a vacuum furnace, which is a special heat-treating chamber that can create an atmosphere of vacuum.
Evacuation Air-
Vacuum furnaces remove air from chambers, creating an oxygen-free space. This can prevent oxidation while ensuring uniform heating.
Heating Phase
The furnace is heated to the temperature required for hardening of dies. The range of temperature is determined by the material type and the process of hardening.
Soaking at High temperatures
The dies must be held at the high temperature for a certain time to allow the material to attain the desired hardness.
Cooling or Quenching
Following the soaking phase it is possible to rapidly cooled using specialized techniques. The rapid cooling process can help to ensure the desired level of strength and hardness of the metal.
Tempering (Optional).
In some cases, the hardening is followed by a tempering procedure. Tempering involves heating the dies up until they reach a temperature that is lower to ease stress and maintain the toughness.
Quality Control and Inspection
The hardened dies undergo thorough quality tests and inspections to confirm that they meet the standards for hardness, strength, and tolerances for dimensionality.
Post-Treatment Handling-
When the process of hardening by vacuum is complete Die dies are then subject to further procedures like polishing or coating prior to being used in the coin or striking process.
The method of vacuum hardening improves die durability, wear resistance, and also the life span of the dies used to create gold or silver coins and medals. This process, which creates an environment that is free of airborne contaminants, guarantees that the dies are honed consistently and safely, which improves the overall quality and longevity of the products.
