What Is The Reason Why Gold Coins Or Medal Dies Undergo Vacuum Hardening?
The process of forming a vacuum for dies in striking gold medals or coins involves placing the dies in extreme temperatures and controlled conditions within a furnace that is a vacuum. Here is a brief overview of the vacuum-hardening process.
When preparing dies to be used in striking coins or other medals, it's crucial that they are clean of contamination or residues.
Moving into Vacuum Furnace
The dies will be placed in a vacuum chamber, that is a specially designed heat-treatment room capable of creating vacuum.
Evacuation via Airplane
The vacuum oven removes all air from the chamber creating an environment free of oxygen as well as other gases. This can prevent burning while ensuring an even heating.
Heating Phase
The furnace has to be heated to the appropriate temperature required for the dies to be hardened. Temperature ranges vary depending on the material used and the hardening processes.
Drinking at high temperatures
The dies have to be kept at a high temperature for a certain period of time in order for the material to attain and maintain its desired level of hardness.
Quenching or cooling-
Utilizing specialized techniques, dies are quickly cooling down or being quenched following the soak process. Rapid cooling assists in locking the desired strength and hardness in the metal.
Tempering (Optional)The Tempering Process (Optional)
In certain cases the tempering process is a part of the hardening process. To improve the toughness and relieve internal stress, dies may be heated to a lower temperature.
Quality Control and Inspection
The hardened dies undergo thorough quality tests and inspections to confirm that they meet the required hardness, strength, and dimensional tolerances.
Post-Treatment Handling-
After the vacuum hardening dies can be polished or coated before they are used in the coin process or the metal striking process.
Vacuum hardening enhances the life endurance, durability, and wear resistance of the dies that are used to strike gold medals or coins. This procedure, which creates an environment that is free of airborne contaminants, guarantees that dies are hardened consistently and reliably, contributing to the overall quality and durability of the products.

How Are Gold Blanks Put Into Coin Presses Under High Pressure And Stamped?
During the minting process, gold blanks are fed into coin presses and stamped under extreme pressure to make into finished pieces of gold or coins. Here's the overview of steps involved in loading blanks.
In a feeder system linked to the press, gold-plated blanks have been previously prepared and quality-tested. This feeder ensures that the blanks are always delivered to the machine.
Feeding Blanks Through the Press
The feeder system is used to feed the blanks into the chamber for striking inside the coin press, one at a. This ensures precise placement of the blanks.
Alignment of Positioning
The blanks are placed and aligned inside the chamber for striking of the press in order to ensure they are perfectly aligned to be used for stamping.
Striving Under Pressure
The coin press presses the gold blanks with high pressure using two dies: one stationary, and the other moving. The stationary coin die provides negative images of the coin design. While the moving die acts as a hammer to hit the blank but the stationary die includes the positive impression.
Dies hit the blank with a lot of force, transferring the design onto its surface. Die pressure creates raised relief and detail on the coin.
Striking repeatedly
In order to create designs or images that are more sharp and more clear, several strikes may be applied on rare coins or collectible editions. Each strike refines the detail inside the blank.
Ejection and collection
After being struck, newly-minted coins or medals are released from the press onto trays or containers. Quality control is carried out to ensure that the designs conform to the specifications.
Post-Processing-
According to the design or mint specifications, coins and medals can be subjected to additional treatments like edge lettering or reeding as well as post-strike treatment.
The process of stamping under extreme pressure is essential in that it transfers the desired design on the gold blanks, transforming them into finished coins or medals ready for use in collection, circulation, or for commemoration. This process requires precision because any deviation in pressure or alignment can alter the appearance and quality of the final product.
