Why Are Dies For Gold Coins Or Medals Vacuum Hardened?
The vacuum hardening of dies used to strike gold medals and coins is achieved by subjecting them to high temperatures under controlled conditions in a vacuum chamber. This is a brief overview of how to harden dies using vacuum.
It is essential that dies used to create medals and coins are completely clean, free of residues and contaminants.
Loading into vacuum Furnace
The dies are then placed inside a specific heat-treating room which can generate the vacuum.
Evacuation of Aircraft
Vacuum furnaces eliminate air from chambers, creating an oxygen-free environment. This is to prevent oxidation as well as ensure uniform heat treatments.
Heating Phase
The furnace needs to be heated to the temperature necessary to harden the dies. The temperature range is based on the material used and the processes for hardening.
Soaking in High Temperatures
Die dies are kept at the elevated temperature for a specified time, allowing the material to reach and keep the desired hardness and the metallurgical structure.
Quenching (or Cooling)
Using specialized methods that allow dies to be quickly cool down or melted after the soak process. The rapid cooling process helps to lock the desired hardness of the material.
Tempering (Optional).
In some cases, the process of hardening can be then followed by a tempering process. Tempering is the process of heating dies to a lower temperature, which helps alleviate internal stress and increase durability while maintaining the their hardness.
Quality Control and Inspection-
Hardened dies are subjected to thorough quality inspections and checks to ensure that they meet the specifications for strength, hardness and tolerances to dimensional measurements.
Post-Treatment Handling-
After the process of vacuum hardening is finished, the dies may undergo further processes like polishing or coating before being utilized in the coin or striking process.
The process of vacuum hardening increases the strength, durability of the dies, their wear resistance and the life of the dies that are used for making gold medals or coins. This process creates a controlled atmosphere free of airborne contaminants to ensure consistent and reliable hardening. This also enhances the quality of the finished product.

How Do You Prepare And Weigh Gold Blanks To Be Used In Minting?
To ensure consistency and accuracy of gold awards or coins, high-quality blanks must be prepared meticulously for minting. This is how and why the process of preparation operates. Gold Material Selection - Only pure gold is utilized to create blanks. The gold is usually refined until it is at the standard of purity required for coinage.
Gold Blanks are created by blanking. Blanking is the cutting of discs and planchets of coins in size, made from gold with specialized machinery.
Accurate Weighting and Measuring
Weighing Every blank is individually weighed to ensure that it meets the specified requirements for the coin. This ensures that the medal or coin has exactly the right quantity of gold.
Measuring - To guarantee uniformity, the diameter, thickness, overall dimensions, and design specifications are adhered to every blank is measured using precision instruments.
Inspection and Control of Quality
Visual Inspection Each piece is assessed visually for surface imperfections, irregularities and impurities. They could affect the quality of the final product.
Rejecting Blanks that Are Not ConformingIf a blanket does not meet the required dimensions, weight or quality standards are rejected to maintain consistency and uniformity.
The Motives for Preparing
Consistency During Minting Process- Accurately weighed and measured blanks made of metal are utilized to ensure uniformity. Weight and dimensions are consistent which results in uniformly striking of medals and coins.
Gold content that is accurateThe exact weight of each coin ensures that the final piece of coin has the exact amount of pure and precise gold.
Uniform Blanks Prevent Variations. Uniform blanks can prevent changes in weight or size that can affect the value of a medal or coin's value, or even legality when it is in circulation.
Quality Assurance - Strict control measures are taken when making blanks to ensure that only the finest quality blanks free from defects, proceed through the process of minting which reduces the risk of flaws appearing in the final product.
Legal Compliance- The coins are designed to be used for circulation or used for commemorative purposes. They must comply with legal requirements along with requirements and standards established by regulators or mints.
It is important to prepare high-quality gold blanks in a consistent way. This ensures that the gold coins and gold medals made are precise, valuable, and legal.
