Why Do Dies Used For Striking Gold Coins Or Medals Undergo Procedures Of Vacuum Hardening?
The vacuum hardening of dies that are used to make gold coins and medals is done by subjecting them to extremely high temperatures under controlled conditions in a vacuum chamber. This article will provide an outline of the vacuum hardening process for dies Preparation and Cleaning.
When creating dies to be used in striking metals or coins, it's important that they are free of contamination or residues.
Injecting Vacuum Furnace
Die dies are placed in a vacuum chamber, which is a specialized heat-treatment room capable of creating vacuum.
Evacuation of Air
The vacuum oven eliminates all air from the chamber and creates a safe environment without oxygen and other gases. This stops oxidation and provides uniform heating.
Heating Phase -
The furnace is preheated to the appropriate temperature for hardening of dies. The temperature range is based on the particular material and the hardening process.
Soaking at high temperatures
The dies will be kept at an elevated temperature for the duration that is required to ensure the material attains and keeps the required hardness.
Quenching or Cooling-
Utilizing specialized techniques using specialized techniques, dies are swiftly cooled down or quenched after the soaking process. This rapid cooling process ensures the required strength and hardness in the steel.
Tempering (Optional).
In some instances, a tempering step is carried out after the hardening stage. The dies are heated up to a lower heat to ease internal stress and increase toughness, while maintaining hardness.
Quality Control and Inspection
To ensure they meet the hardness and strength requirements the dies that are hardened undergo a thorough inspection and quality control.
Post-Treatment Handling-
The dies, after the process of vacuum-hardening has been completed, may be further processed using polishing and coating, before they are utilized in the strike of coins or medals process.
The process of vacuum hardening increases the durability of dies and wear resistance, as well as the longevity of dies used to strike gold or silver coins and medals. The process of hardening by vacuum is a reliable and consistent way to ensure that dies are hardened in a controlled environment that's free of any contaminants.
