The vacuum oven removes any air in the chamber making it a clean space free of oxygen and other gases. This can prevent the oxidation process while also ensuring a the same heating.
Heating Phase -
The furnace is then heated to the temperature desired for hardening dies. Temperature ranges vary depending on the materials used and the process of hardening.
Soaking at High temperatures
The dies will be kept at a high temperature for the duration that is necessary to ensure that the material is able to reach and maintain the required hardness.
Cooling and cooling as well as quenching
With the help of special techniques using specialized techniques, dies are swiftly cooling down or being quenched following the soaking process. Rapid cooling assists in locking the desired strength and hardness in the metal.
Tempering (Optional).
In some cases, a tempering process follows the hardening process. Tempering is the process of heating dies at a low temperature to ease internal tensions and increase toughness.
Quality Control and Inspection
Die dies are subjected to rigorous quality checks and inspections to make sure they are in compliance with the requirements for toughness, hardness, and tolerances to dimensional dimensions.
Post-Treatment Handling-
The dies will be processed further, such as coating or polishing, prior to being used for the coins or medals.
Vacuum hardening improves the durability as well as the toughness and wear resistance of the dies that are used to create gold medals or coins. This procedure creates a controlled environment that is free of contaminants from the atmosphere to guarantee consistent and reliable hardening.
