Why Do The Dies Used For Striking Gold Coins Or Medals Undergo Procedures Of Vacuum Hardening?
Vacuum hardening is a process which involves exposing dies to extreme temperatures and a controlled environment in the furnace. Here's a brief overview of the process for dies Preparation and Cleaning.
When creating dies to be used to strike coins or other medals, it's crucial that they are clean of contamination or residues.
Injecting Vacuum Furnace
The dies are placed inside a special heat-treating chamber that creates the vacuum.
Evacuation from the Air
The vacuum furnace eliminates air from the room, forming a controlled vacuum environment devoid of oxygen and other gasses. This guarantees uniform heating and prevents the process of oxidation.
Heating Phase
The furnace is preheated to the required temperature to allow the dies to harden. The temperature range depends upon the specific material used and the process of hardening.
Soaking in high temperature
Die dies are kept at temperatures that are high for the duration that is needed to make sure the material attains and keeps the required hardness.
Quenching or Cooling
Following the soaking process after which the dies are cooled or quenched using specialized methods. This rapid cooling procedure aids in locking the desired hardness in the steel.
Tempering is not required.
In certain instances, a tempering step is carried out following the stage of hardening. In order to improve strength and reduce the internal strain, dies could be heated at temperatures lower.
Quality Control and Inspection
The hardened dies undergo thorough quality tests and inspections to confirm they are in compliance with the requirements for hardness, strength, and tolerances for dimensionality.
Post-Treatment Handling-
The dies will be subjected to further processing including coating or polishing, prior to being used for the strike of the coin or medal.
The process of forming a vacuum enhances the strength, durability and wear resistance and longevity of dies, which are used for striking coins or medals. By ensuring a controlled and free of contaminants it provides a consistent and reliable way to make the dies harder.
