Why Does A Gold Coin Or Medal Dies Undergo The Process Of Hardening By Vacuum?
To make dies harder for gold coinage or medals, they're subjected to controlled temperatures inside the vacuum oven. Here's a quick overview of how to vacuum harden dies.
The dies used for striking medals or coins are created by making sure they are free of any traces of contamination or residues.
Loading into vacuum furnace
The dies go into a vacuum-environment chamber.
Evacuation by Airplane
The vacuum oven removes all air from the room creating an environment free of oxygen and other gases. This is done to avoid oxidation as well as guarantee uniform heat treatment.
Heating Phase
The furnace has to be heated to the appropriate temperature necessary to harden the dies. The temperature will depend on the material that is used and the way it will be hardened.
Soaking in high temperature
Die dies are kept at a high temperature for the exact duration needed to make sure the material is able to reach and maintain the desired level of hardness.
Quenching or Cooling
The dies are then quickly cooled or quenched after the soaking. This fast cooling process assists in locking the desired hardness in the steel.
Tempering (Optional).
In certain situations the process of tempering may follow the process of hardening. Tempering involves heating dies to a lower temperature to ease 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 specifications for strength, hardness and tolerances to dimensional measurements.
Post-Treatment Handling-
After the vacuum hardening, dies can be polished or coated prior to when they are used in the coin process or the metal striking process.
Vacuum hardening improves the durability as well as the durability and wear resistance of dies that are used to create gold medals or coins. By creating a controlled environment free from atmospheric contaminants the process ensures constant and reliable hardening the dies, contributing to the durability and quality of the products that are minted.

Why And How Are Gold Blanks Of Superior Quality Measured And Weighed Before The Process Of Minting Begins?
The finest gold blanks are expertly prepared for the minting process to ensure exact and consistent gold medals or coins. This is the procedure that is followed: Preparation Gold Selection of the Material- Only high purity gold is used for creating blanks. The gold is typically refined to be in compliance with specific purity requirements for coinage.
Gold Blanks Production- Gold is transformed into blanks by the process of blanking or cutting blanks. Blanking refers to the process of cutting discs or planchets to the size of coins from gold by using special equipment or stamping.
Precise Measuring and Weighing
Weighing- Every blank is weighed individually to ensure it meets the specified weight criteria for the coin or medal. This ensures that every medal or coin contains precisely the quantity of gold needed for the denomination it is intended to be.
Measuringthe diameter, thickness, as well as the overall dimension of every blank are measured with precision instruments to ensure consistency and conformity to design specifications.
Quality Control and Inspection
Visual Inspection Every blank is scrutinized visually for surface imperfections, irregularities and impurities. They could affect the quality of the final product.
Rejecting blanks with non-conformity In order to maintain consistency and uniformity, all blanks that don't comply with the weight, dimensions or quality standards are rejected.
Why is it important to prepare?
Consistency in the Minting Process Accurately measured and weighed blanks will ensure uniformity. The consistency of weight and size results in uniform striking. This creates coins or medals of the same quality and worth.
Accurate Gold Content: Each blank is weighed precisely to ensure that the final piece of coin, or medal, contains exactly the amount of gold needed. This guarantees accuracy in both value and purity.
Uniform Blanks Avoid Variations. Uniform blanks can prevent variations in size or weight that can affect the value of a medal or coin's value or legality in circulation.
Quality Assurance- Strict quality control measures during blank preparation will ensure that only high-quality, defect-free blanks go through the process of minting, which reduces the chance of defects appearing on the finished product.
Legal Compliance: Uniformity and compliance with specifications are essential in coins that are intended for use in commemorative or circulation for purposes. They must meet the legal requirements and standards laid out by mints and regulatory bodies.
The accuracy and precision in the preparation of gold blanks that are high-quality are crucial aspects of the minting process. They ensure the production of accurate and high-value legal conforming gold coins or medals.

How Do Gold Blanks Get Fed Into Coin Presses Under Extreme Pressure? And Then Stamped?
When minting, gold coins and medals are produced by stamping them under pressure. This is a brief overview of the steps involved in loading blanks.
In a feeder system that is connected to the press, gold-plated blanks have already been prepared and tested for quality. This feeder system will provide the constant supply of blanks to the coin press.
Blanks for Feeding to the Press
This feeder system makes sure that each blank is positioned precisely inside the chamber of stamping. This assures the precise positioning of each stamping blank.
Alignment, Positioning and Positioning
Inside the press, blanks are aligned and positioned in the chamber for striking making sure that they are completely centered and aligned for the stamping process.
Moving under Pressure
The coin press is made up of two dies: one stationary and one that moves. The stationary coin die provides negative images of the coin's design. The moving die acts as a hammer to strike the blank while the stationary one contains the positive impression.
Dies hit the blank with lots of force, transferring the design on its surface. Die pressure causes relief raised and details on the coin.
Striking repeatedly
For higher-quality coins or medals, especially proof or collector's editions, multiple strikes could be applied to achieve a sharper, more defined appearance or style. Each strike further refines the finer details of the surface of the blank.
Ejection and Collection
After being struck, newly-minted coins or medals are released out of the press into containers or trays. Quality control is performed to ensure the designs adhere to the specifications.
Post-Processing-
The design of the coin or medal could require further processing, such as edge lettering (either edge reeding) or post-strike treatment.
Stamping the gold blanks with high pressure is vital because it prints the design desired onto them, turning them into refined coins and medals which can be used for celebration and collection, or even circulation. The stamping process requires preciseness as slight changes in alignment and pressure can influence the final product's quality.
