What Are The Reasons Why The Dies Used Strike Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
The vacuum hardening of dies that are used to make gold medals and coins is accomplished by exposing them to high temperatures under controlled conditions in a chamber. Here's a quick guide on how to vacuum harden dies.
It is essential that the dies used to strike medals and coins are completely clean, free of dirt and other contaminants.
Loading in Vacuum Furnace
The dies are placed inside the vacuum furnace, which is a specialized chamber for heat treatment that is capable of creating an atmosphere of vacuum.
Evacuation of Aircraft
Vacuum furnaces remove air from chambers, resulting in an oxygen-free atmosphere. This prevents oxidation and ensures the same heat treatment.
Heating Phase
The furnace is heated to a certain temperature to solidify the dies. The temperature is determined by the material being used and the method by which it will be cured.
Soaking at high temperatures-
Die dies are kept at a high temperature for a specific time which allows the material to achieve and keep the desired hardness and metallurgical structure.
Cooling and Quenching
Following the soaking phase, the dies can be quickly cooled with the help of specialized techniques. The speedy cooling allows the metal to achieve the required hardness.
Tempering (Optional)The Tempering Process (Optional)
In certain cases, a tempering process follows the process of hardening. Tempering is the process of heating dies to a lower temperature, which helps alleviate internal stress and increase toughness while maintaining their hardness.
Quality Control and Inspection
Dies with hardened material must undergo rigorous quality control and inspections to attain the desired hardness, strength or dimensional tolerances.
Post-Treatment Handling-
When the process of hardening by vacuum is completed Die dies are then subject to further processes like polishing or coating prior to being utilized for the coin or medal striking process.
The process of hardening by vacuum increases the wear resistance, durability and longevity of dies used to make gold coins or medals. This procedure, which creates an atmosphere free of airborne contaminants, ensures that dies are consistently hardened and consistently, enhancing both the quality and durability of the products.
