Why Do Dies Used For Striking Gold Coins Or Medals Go Through Vacuum Hardening Processes?
Vacuum hardening is a process that involves exposing dies to extreme temperatures and a controlled environment in the furnace. This is an overview of the process of vacuum hardening for dies.
To make dies that will be used to make coins or medals, they must be free of any contaminants or residues.
Loading into vacuum furnace
The dies are inserted into the vacuum furnace. It is a specialized chamber for heat treatment that is capable of creating an atmosphere of vacuum.
Evacuation of Air
The vacuum furnace removes air from the chamber, creating the perfect vacuum, free of oxygen and other gases. This is to prevent oxidation as well as ensure uniform heat treatments.
Heating Phase
The furnace must be heated to the appropriate temperature required for the dies to be hardened. The range of temperatures is determined by the particular material and the processing for hardening.
Soaking in High Temperatures
The material can reach the desired hardness and the metallurgical structure is created.
Cooling or quenching
With the help of special techniques using specialized techniques, dies are swiftly cool down or melted after the soak process. This process of rapid cooling helps to ensure the desired level of strength and hardness of the metal.
Tempering is optional
In certain instances, a tempering step is carried out following the hardening phase. Tempering is the process of heating dies to a lower temperature in order to relieve internal tensions and improve durability.
Quality Control and InspecQuality Control and Inspection
Dies that are hardened must go through rigorous quality control and inspections to attain the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
Die dies are coated or polished and then used to create coins or medals.
The process of hardening by vacuum increases the wear resistance, durability, and lifespan of the dies used to create gold medals or coins. This process creates a controlled atmosphere free of atmospheric contaminants to ensure consistent and reliable hardening. It also contributes to the overall quality of the minted product.
