What Is The Reason That Dies Used To Strike Gold Coins Or Medals Undergo The Process Of Hardening By Vacuum?
The process of forming dies that are that are used to make gold coins and medals is accomplished by exposing them to high temperatures under controlled conditions inside a vacuum chamber. Here is a brief overview of the process of vacuum hardening.
It is crucial that dies used for striking medals and coins are completely free of any contamination and residues.
Moving into Vacuum Furnace-
The dies are placed inside a specific heat-treating room that creates a vacuum.
Evacuation Air
Vacuum furnaces remove air from chambers, creating an oxygen-free space. This stops oxidation and provides an even heat treatment.
Heating Phase
The furnace is heated up to the desired temperature needed to harden the dies. The temperature range varies based on the material and processing for hardening.
Soaking in high temperature
Die dies are kept at the elevated temperature for a specified time, allowing the material to attain and maintain the desired hardness and the metallurgical structure.
Quenching or Cooling
Following the soaking process after which the dies are cooled or quenched using specialized techniques. The quick cooling assists the metal reach the required hardness.
Tempering (Optional).
In some instances, the hardening is followed by a tempering procedure. In order to improve strength and reduce internal stress, dies could be reheated at temperatures lower.
Quality Control and Inspection
Dies with hardened surfaces are subjected to thorough quality inspections and checks to ensure they meet standards for strength, hardness and tolerances for dimensional dimensions.
Post-Treatment Handling-
Die dies are coated or polished, and used to strike coins or medals.
The process of vacuum hardening enhances the durability and wear resistance and the life span of dies employed to make coins or medals. The process of vacuum hardening is a reliable and predictable method to make dies hard in a controlled environment that's free of any contaminants.
