Why Does A Gold Coin Or Medal Dies Undergo A Process Of Vacuum Hardening?
Vacuum hardening is a procedure that involves exposing dies high temperature and controlled environment in a furnace. This is a brief description of the vacuum-hardening process.
When preparing dies to be used to strike coins or other medals, it's essential that they are free of residues or contamination.
Moving into Vacuum Furnace
Die dies are placed in a vacuum-environment chamber.
Evacuation of Aircraft
Vacuum furnaces eliminate air from chambers, creating a non-oxygen space. This helps to prevent the oxidation process while also ensuring a uniform heat treatment.
Heating Phase
The furnace is heated to the ideal temperature needed to harden the dies. The temperature range depends on the material used and the hardening process.
Bathing in high temperatures
Die dies are kept at temperatures that are high for the time needed to make sure the material reaches and maintains the desired level of hardness.
Quenching (or cooling)
Using specialized methods, dies are quickly cooling down or being quenched following the soak process. The rapid cooling process aids in locking the desired hardness into the material.
Tempering (Optional).
In certain cases it is possible to temper after the hardening process. Tempering is the process of heating dies to a lower temperature in order to release internal tensions and improve toughness.
Quality Control and Inspection
The hardened molds are thoroughly examined and tested to make sure that the dies meet the requirements.
Post-Treatment Handling-
After the vacuum hardening dies are polished or coated prior to when they are used in the coin or metal strike process.
The process of forming a vacuum improves the strength, durability, resistance to wear, and the life span of dies, which are used for striking medals or coins. By ensuring a controlled and clean environment the process offers an efficient and consistent method to make the dies harder.
