What Is The Reason Why Dies Used To Make Gold Medals And Coins Undergo Vacuum-Hardening Processes
In order to harden dies for gold coins or medals, they're subjected to temperature control in an oven that is a vacuum. This is the basic information on vacuum hardening dies.
To prepare dies that will be used to strike coins or medals, they should be clean and free from any contamination or residues.
Loading into vacuum furnace
The dies are placed inside the vacuum furnace, which is a specialized heat-treating chamber that can create a vacuum environment.
Evacuation Air-
The vacuum oven removes any air in the room making it a clean space free of oxygen and other gases. This helps prevent oxidation and guarantees the same heat treatment.
Heating Phase
The furnace needs to be heated to the appropriate temperature required for the dies to be hardened. The temperature is determined by the material being used and the method by which it will be shaped.
Soaking at High temperatures
Die dies are kept at the elevated temperature for a specified time, allowing the material to attain and retain the desired hardness as well as the metallurgical structure.
Quenching (or Cooling)
The dies will be quenched or rapidly cooled after soaking. The rapid cooling helps the metal achieve the desired level of hardness.
Tempering is an option
In some instances, a tempering step is performed after the hardening stage. To improve the strength and reduce internal stress, dies can be heated at a lower temperature.
Quality Control and Inspection
To make sure they meet the specifications for strength and hardness, hardened dies go through an exhaustive inspection and quality check.
Post-Treatment Handling-
The dies, following the process of forming a vacuum has been completed, may be further processed like polishing and coating, before they are used in coin striking or medal striking methods.
The vacuum hardening procedure enhances the durability of the dies, their wear resistance and the life of the dies for striking gold medals or coins. This process produces a controlled and safe environment that is free of contaminants from the atmosphere to ensure consistent and reliable hardening. This also enhances the quality of the finished product.
