What Are The Reasons Why The Dies Used Strike Gold Coins And Medals Undergo Vacuum-Hardening Processes
Vacuum hardening is a process which involves exposing dies to high temperature and controlled environment in a furnace. Here's a brief overview of the procedure for die preparation and Cleaning-
When making dies that will be used for striking coins or other medals, it's crucial that they are clean of contamination or residues.
Moving into Vacuum Furnace-
Die dies are then put in a specially designed heat-treating chamber which can generate the vacuum.
Evacuation from the Air
The vacuum furnace removes air from the chamber, creating an environment of controlled vacuum that is free of oxygen or other gases. This stops oxidation and provides uniform heat treatment.
Heating Phase
The furnace is then heated to the desired temperature in order to harden the dies. The range of temperatures is determined by the particular material and the processes for hardening.
Soaking at high temperatures-
The material is allowed to reach the desired hardness and the metallurgical structure.
Cooling or Quenching
The dies will be immediately cooled off or quenched following soak. This rapid cooling process helps lock in the desired toughness and durability of the steel.
Tempering (Optional)Tempering (Optional)
In a few cases, a tempering step occurs following the hardening phase. Tempering is the process of reheating dies at a low temperature in order to relieve internal tensions and increase toughness.
Quality Control and Inspection
Dies with hardened material must undergo rigorous quality control and inspections in order to achieve the desired strength, hardness or tolerances.
Post-Treatment Handling-
The dies, following the process of vacuum-hardening is complete, could be further processed, such as polishing and coating prior to when they are utilized in the coin striking or medal striking processes.
The process of forming a vacuum improves the durability, resistance to wear, and longevity of dies that are used for striking medals or coins. This process, which creates an atmosphere free of airborne contaminants, ensures that the dies are honed consistently and reliably, contributing to both the quality and longevity of the product.
