Why Are Dies For Gold Coins Or Medals Vacuum Hardened?
Vacuum hardening is a procedure that involves exposing dies high temperatures and a controlled atmosphere in a furnace. This article provides an overview of the procedure of vacuum hardening for dies.
Diets for striking medals or coins are clean and free of contaminants.
Moving into Vacuum Furnace
The dies will be placed in a vacuum chamber that is a specially designed heat-treatment room that can create vacuum.
Evacuation with Airplane
Vacuum furnaces draw air out of chambers, resulting in an oxygen-free environment. This is done to avoid the formation of oxidation and to ensure uniform heat treatments.
Heating Phase
The furnace is heated to the temperature required for hardening the dies. The temperature range will be determined by the material type and the process of hardening.
Soaking at high temperatures
Die dies need to be kept at the highest temperature for a specified period of time in order for the material to achieve and maintain its desired hardness.
Cooling or quenching
After the soaking phase it is possible to rapidly cooled using specialized methods. Rapid cooling assists in locking in the desired hardness and strength in the metal.
Tempering (Optional).
In certain cases, process of hardening can be then followed by a tempering process. The dies are reheated at a lower temperature in order to ease internal stress and increase durability, while preserving hardness.
Quality Control and Inspection
To make sure they meet the hardness and strength requirements the dies that are hardened undergo an exhaustive inspection and quality test.
Post-Treatment Handling-
The dies, after the process of vacuum-hardening is completed, can be further processed using polishing and coating, before they are utilized in the strike of coins or medals process.
Vacuum hardening enhances the life, toughness and wear resistance of the dies that are used to create gold medals or coins. This process, which creates a safe atmosphere free of airborne pollutants, assures that dies are hardened consistently and safely, which improves both the quality and durability of the products.
