Why Does A Gold Coin Or Medal Dies Go Through The Process Of Hardening By Vacuum?
To make dies harder for gold coinage or medals, they are exposed to controlled temperatures inside an oven that is a vacuum. This is a brief overview of how to make dies harder by vacuum.
The dies used for striking coins or medals are made by ensuring they are clean and free from any residues or contaminants.
Moving into the vacuum furnace
The dies will be put in a vacuum chamber which is an specialized heat-treating room that can create vacuum.
Evacuation Air-
The vacuum oven removes all air from the room creating an environment free of oxygen and other gases. This is to prevent oxidation as well as ensure uniform heat treatments.
Heating Phase
The furnace is heated to the desired temperature in order to harden the dies. The temperature range is determined by the material type and the hardening process.
Soaking in High Temperatures
The dies will be kept at a high temperature for the time needed to make sure the material attains and keeps the desired level of hardness.
Cooling or cooling down
Die dies are quenched or rapidly cooled after soaking. The rapid cooling process aids in locking the desired hardness of the metal.
Tempering (Optional).
In some situations, a process of tempering may follow the process of hardening. Tempering involves reheating dies at a low temperature in order to relieve internal tensions and improve the toughness.
Quality Control and Inspection
Dies with hardened surfaces are subjected to thorough quality inspections and checks to ensure they meet requirements for hardness, strength and tolerances for dimensional dimensions.
Post-Treatment Handling-
After the process of vacuum hardening dies can be polished or coated prior to the time they are used in the coin process or the metal striking process.
Vacuum hardening improves the durability endurance, durability and wear resistance of dies that are used to create gold coins or medals. This process creates a controlled atmosphere that is free of contaminants from the atmosphere to guarantee consistent and reliable hardening. This also enhances the overall quality of the final product.
