Why Is Vacuum Hardening Used On Dies That Are Used To Make Gold Coins Or Medals?
In order to harden dies for gold coins or medals, they are exposed to controlled temperatures inside the vacuum oven. This is a brief overview of how to harden dies using vacuum.
The dies used for striking coins or medals are prepared by making sure they are clean and free from any traces of contamination or residues.
Loading in Vacuum Furnace
The dies will be placed in a vacuum chamber, that is a specially designed heat-treatment room capable of creating vacuum.
Evacuation Air-
The vacuum oven eliminates all air from the room making it a clean space free of oxygen and other gases. This prevents oxidation and ensures uniform heat treatment.
Heating Phase
The furnace is heated to the ideal temperature required for hardening the dies. Temperatures can vary based on the material and process of hardening.
Soaking at high temperatures-
The dies remain at the elevated temperatures for a specified period of time, which allows materials to attain the desired hardness level and also maintain the metallurgical structure.
Quenching or cooling-
After soaking, the dies are rapidly cooling or quenched by using special methods. This rapid cooling process helps lock in the desired strength and hardness of the steel.
Tempering is an option
In certain situations tempering may follow the process of hardening. In order to improve strength and reduce the internal strain, dies can be reheated at temperatures lower.
Quality Control & Inspection
Die dies that are hardened undergo thorough quality inspections and checks to ensure that they meet the specifications for strength, hardness and dimensional tolerances.
Post-Treatment Handling-
After the process of vacuum hardening, dies can be polished or coated prior to when they are used in the coin process or metal striking process.
The process of hardening by vacuum increases the strength, wear resistance and life span of dies used for striking gold medals or coins. The process of vacuum hardening is a reliable and consistent way to harden dies in a controlled environment that's free of any contaminants.
