Why Do Dies Used To Strike Gold Coins Or Medals Go Through Procedures Of Vacuum Hardening?
The process of vacuum hardening used to make dies for striking gold coins or medals involves making the dies subject to extreme temperatures and controlled environments in a vacuum furnace. This is a brief description of the process for forming a vacuum.
Diets for striking medals or coins are clean and free of contaminants.
Loading Vacuum Furnace
Die dies are placed in a vacuum-environment chamber.
Evacuation of Aircraft
The vacuum furnace eliminates the air in the chamber to create an environment controlled by vacuum that is free of oxygen and other gasses. This eliminates oxidation, and ensures uniform heat treatment.
Heating Phase
The furnace has to be heated to the appropriate temperature required for the dies to be hardened. The temperature range is based on the particular material used as well as the method of hardening.
Soaking at high temperatures
The material can achieve the desired hardness and the metallurgical structure is created.
Quenching (or Cooling)
After the soaking, dies have to be cooled quickly using specialized techniques. The rapid cooling process locks in the desired toughness and hardness of the metal.
Tempering (Optional).
In some instances, the process of hardening can be followed by a tempering process. Tempering is the process of heating dies to a lower temperature to ease internal tensions and improve the toughness.
Quality Control Inspection
Hardened dies must pass thorough quality control and inspections to ensure they achieve the desired hardness, strength or dimensional tolerances.
Post-Treatment Handling-
When the process of hardening by vacuum is completed Die dies are then subject to further procedures like polishing or coating prior to being used for the coin or medal striking process.
The vacuum hardening method increases die durability, wear resistance, as well as the lifespan of the dies used to create gold or silver coins and medals. This process, which creates a safe atmosphere free of airborne contaminants, ensures that dies are hardened consistently and reliably, contributing to both the quality and durability of the products.

How And Why Do High-Quality Gold Blanks Get Weighed, Assessed And Ready For Minting?
To make gold-plated coins or gold medals which are accurate and consistent gold blanks must be meticulously prepared. The process of preparation for gold blanks is explained below. The gold is usually refined to meet the specific quality standards for coinage.
Gold Blank Production The gold is turned into blanks using a method called blanking or cutting. Blanking involves cutting coin-sized discs or planchets from the gold material using specialized machines or stamping techniques.
Precision Measuring and Weighing
Weighing- Every blank is individually weighed to ensure it meets the specified weight criteria for the coin or medal. This ensures each piece has the exact amount of gold needed for the amount desired.
Measurements- Every blank is inspected to determine if it complies with the specifications of the design and is uniform.
Inspection and Quality Control
Visual Inspection: Each product is inspected visually to detect imperfections on the surface, irregularities, or impurities that could affect the quality of the final product.
Rejecting Nonconforming Blanks To ensure consistency, we reject blanks that are not in conformity to the requirements for dimensions, weights, and quality standards.
The reasons for preparing
Consistency of Minting Process. Weighted precisely and measured blanks ensure consistency throughout the process of minting. Dimension and weight consistency leads to uniform striking and results in medals and coins that are of the same value and quality.
Accurate Gold Content - Each blank is weighed precisely to ensure that the final piece of coin, or medal, contains the exact amount of gold intended. This assures precision in terms of value and purity.
Preventing Variations Uniform blanks are free of variations in weight and size that could affect the worth of the coin or medal and its legality, or the ability to be utilized in circulation or commerce.
Quality Assurance- Strict quality control measures throughout blank preparation ensure that only top-quality, non-defect blanks go through the minting process, reducing the likelihood of flaws in the final product.
Legal Conformity - It is crucial that coins intended for purpose of circulation or commemoration adhere to the specifications and conform to legal requirements.
Making high-quality blanks that are made with precision and consistency is a crucial element of the minting process. This ensures the creation of gold coins that are precise and medals that are of high in value and conform to the law.
