Why Do Dies Used To Create Gold Coins And Medals Undergo A Process Of Vacuum-Hardening?
The technique of vacuum hardening is utilized in the manufacturing of gold coins or medals. It involves heating dies to high temperatures, and expose them to controlled conditions within the confines of a vacuum. This article provides an overview of vacuum hardening for dies.
When preparing dies to be used for striking metals or coins, it's important that they are free of any residues or contaminants.
Injecting Vacuum Furnace-
Die dies are placed inside a chamber of vacuum, that is a specially designed heat-treatment room that can create vacuum.
Evacuation via Airplane
Vacuum furnaces draw air out of chambers, creating a non-oxygen space. This is done to avoid burning and also to ensure uniform heat treatments.
Heating Phase
The furnace needs to be heated to a temperature necessary to harden the dies. The temperature will depend on the material that is used and the way it will be shaped.
Bathing at high temperatures-
The dies have to be kept at a highest temperature for a specified period of time in order for the material to attain and maintain its desired hardness.
Quenching or cooling
Using specialized methods using specialized techniques, dies are swiftly cool down or melted after the soaking process. Rapid cooling helps to lock in the desired hardness and strength within the metal.
Tempering (Optional)Tempering (Optional)
In some instances the process of tempering may occur after hardening. Tempering is the process of heating dies up to a cooler temperature to relieve stress while maintaining their toughness.
Quality Control and Inspection-
The hardened molds are thoroughly examined and tested to make sure that the dies satisfy all the specifications.
Post-Treatment Handling-
Die dies are then polished or coated, and are used to make coins or medals.
The process of hardening by vacuum enhances the strength, durability as well as the wear resistance and life span of the dies that are used for making gold coins or gold medals. By ensuring a controlled and clean environment, this process provides an efficient and consistent method to ensure that the dies are hardened.
