Why Do Gold Coin Or Medal Dies Go Through The Process Of Hardening By Vacuum?
Vacuum hardening is a procedure that involves exposing dies high temperatures and a controlled atmosphere in a furnace. This article provides a quick overview of the process of vacuum hardening.
Dies used to create coins or medals are prepared by ensuring that they are free of any contaminants or residues.
Loading into Vacuum Furnace-
The dies will be placed in a vacuum chamber, which is an specialized heat-treating room capable of creating vacuum.
Evacuation of Aircraft
Vacuum furnaces eliminate air from chambers, creating an oxygen-free atmosphere. This helps to prevent oxidation while ensuring uniform heat treatment.
Heating Phase
The furnace is then heated to the desired temperature to solidify the dies. The temperature range depends upon the particular material used as well as the process of hardening.
Bathing at high temperatures-
Die dies are kept at the elevated temperature for a specified time, allowing the material to reach and maintain the desired hardness and metallurgical structure.
Quenching or Cooling
After the soaking, dies must be quickly cooled with special methods. Rapid cooling helps to lock the desired strength and hardness within the metal.
Tempering (Optional).
In some cases the process of tempering may occur after the process of hardening. Tempering involves heating dies to a lower temperature to ease internal tensions and improve the toughness.
Quality Control and Inspection-
Die dies are subjected to rigorous quality checks and inspections to ensure they are in compliance with the requirements for hardness, strength, and tolerances to dimensional dimensions.
Post-Treatment Handling-
Die dies are then later subjected to further treatment like coating or polishing, prior to being used for coins or medals.
The process of hardening by vacuum increases the wear resistance, durability and life span of dies used for striking gold coins or medals. This procedure creates a controlled environment free of airborne contaminants to ensure a consistent and reliable process of hardening. It also contributes to the quality of the finished product.

How And Why Are Gold Blanks Of High Quality Weighed And Measured Prior To The Process Of Minting Begins?
In order to create gold-plated coins or gold medals that are precise and consistent gold blanks have to be carefully prepared. The preparation process involves Gold Material Select - For the production of blanks it is necessary to select a high-purity metal. The gold is refined to meet specifications for purity needed for coinage.
Gold Blank Production- The gold is formed into blanks through the process of blanking, also known as blank-cutting. Blanking involves cutting coins-sized disks, or planchets, from the gold material.
Precise Measuring and Weighing
Weighing - Each blank will be individually weighed to ensure it is in line with the weight requirements of the coin or the medal. This method ensures that each piece has the exact quantity of gold required to meet the denomination intended for.
Measuring. Precision instruments are used to determine the diameter, height, and length of each blank. This guarantees the uniformity of measurements and conformity with the specifications of the design.
Inspections and Quality Control
Visual Inspection Each piece is scrutinized visually for surface imperfections, irregularities and impurities. They could have an impact on the quality of the final product.
Rejecting Sheets that Are Not Conforming - To ensure consistency Blanks that don't meet the required standards in terms of weight, dimensions or quality are rejected.
Why is it important to prepare?
Consistency of the Minting Process - The uniformity of the process is assured by precisely weighing and measuring blanks. The consistency of weight and size result in a uniform strike. This creates coins or medals that are the same quality and worth.
Accurate Gold Content - Each blank's exact weight ensures that the final coin or medal is filled with the right amount of gold, ensuring high-quality and precision in value.
Uniform Blanks - Avoid variations of weight or size that could affect the value of the coin or medal legality, usability or circulation or commerce.
Quality Assurance- Strict quality control measures during blank preparation ensure that only top-quality, non-defect blanks proceed to the process of minting, which reduces the possibility of defects on the finished product.
Legal Compliance - It is important that coins for commemorative or circulation purposes adhere to specifications and meet legal specifications.
In order to produce accurate, high value legal compliant coins or medals, it's crucial that gold blanks are created with accuracy and precision.
