What Is The Reason Dies For Gold Medals Or Coins Are They Hardened By Vacuum?
To make dies harder for gold coinage or medals, they're subjected to controlled temperatures in the vacuum oven. Here's a brief overview of vacuum hardening dies.
When making dies that will be used for striking metals or coins, it's essential that they are free of any residues or contaminants.
The loading process is done in the vacuum Furnace
Die dies are placed inside a chamber of vacuum, which is a specialized heat-treatment room that can create vacuum.
Evacuation of Aircraft
The vacuum chamber is made by eliminating air from the chamber and establishing a controlled environment that is devoid or oxygen. This prevents oxidation while ensuring the same heating.
Heating Phase
The furnace is preheated to the required temperature to allow the dies to harden. The range of temperatures will be determined by the type of material and the hardening process.
Bathing in high temperatures
The material can reach the desired hardness, as well as the metallurgical structure is created.
Quenching (or cooling)
After soaking, the dies must be quickly cooled with special methods. The speedy cooling allows the metal to achieve the desired hardness.
Tempering is optional
In some instances the tempering process occurs following the stage of hardening. Tempering involves heating the dies to a lower temperature in order to relieve stress while maintaining the toughness.
Quality Control and Inspection
To make sure they meet the standards for hardness and strength the dies that are hardened undergo a thorough inspection and quality check.
Post-Treatment Handling-
After the vacuum hardening dies are polished or coated prior to when they are utilized in the coin or the metal striking process.
The vacuum hardening process enhances the strength, wear resistance and longevity of dies used to make gold coins or medals. This procedure creates a controlled environment that is free of contaminants from the atmosphere to ensure a consistent and reliable process of hardening. It also contributes to the overall quality of the finished product.
