Why Do Gold Coin Or Medal Diets Undergo A Process Of Vacuum Hardening?
The process of vacuum hardening used for dies in striking gold coins or medals involves placing the dies in extreme temperatures and controlled environments in a vacuum furnace. Here's a quick overview of how to make dies harder by vacuum.
Diets used to strike medals or coins are cleaned and free of contaminants.
Loading Vacuum Furnace
The dies are placed inside the vacuum furnace. It is a specially designed heat-treating chamber that can create a vacuum environment.
Evacuation of Air-
The vacuum chamber is constructed by taking air out of the chamber and creating an atmosphere that is completely free of oxygen. This assures uniform heating, and also prevents the oxidation process from occurring.
Heating Phase
The furnace must be heated to the temperature necessary to harden the dies. The temperature will depend on the material used as well as the way it will be hardened.
Soaking in High Temperatures
The dies are held at a high temperature for a specific time, allowing the material to achieve and retain the desired hardness as well as metallurgical structure.
Quenching or Cooling-
After the soaking period, the dies are rapidly cooled or quenched using specialized methods. The rapid cooling process ensures the required toughness and hardness of the steel.
Tempering Options
In some cases, the process of hardening can be followed by a tempering procedure. Die dies are heated at a lower temperature in order to reduce internal stress and improve toughness, while maintaining hardness.
Quality Control Inspection
To ensure they meet the standards for hardness and strength the dies that are hardened undergo a thorough inspection and quality control.
Post-Treatment Handling-
After the vacuum hardening dies are polished or coated before they are utilized in the coin or metal striking process.
The process of vacuum hardening enhances the durability of the dies, their wear resistance and the life of the dies used to create gold coins or medals. By ensuring a controlled and contaminant-free environment it provides a consistent and reliable way to harden the dies.

Why Should Dies Be Polished By Hand To Get A Perfect Finish On Gold-Plated Coins And Awards?
The hand polishing of dies is necessary for the production of gold medals and coins. This is due to the fact that it helps in the reproduction of fine detail. The smooth surfaces permit a better reproduction of fine details and intricate features on the struck medals or coins.
The polished die will ensure that the medals and coins made are sharp and have clearly defined details, and relief. This increases the aesthetic and quality of the final product.
Polishing helps to reduce wear and tear that occurs during the process of striking. Smooth surfaces reduce the chance of errors or inconsistencies that are caused to the medal or coin struck by rough surfaces.
Consistency of Striking Die dies that are hand-polished ensure uniformity throughout the process of minting, by providing a consistent strike area. To ensure that the design is maintained in its precision as well as its depth and overall quality, consistency is essential.
Durability and longevity of Dies- Well polished dies are less prone to being damaged or wear while striking. They last longer and are more robust, which allows for more strikes, without compromising quality.
Accuracy and Precision Hand polishing allows engravings to fine-tune and refine specific areas of the die. This ensures that all details are accurately reproduced on struck coins or medals. The accuracy of a finished product is improved by this level of precision.
Quality Control – Polishing forms an element of a quality control process. The die can be inspected as it is polished by hand to detect any defects or inconsistencies, and then corrected prior to the strike.
Surface Finish Polishing can be used to create a unique appearance or surface, which enhances the aesthetic appeal of coins or medals, or give them unique particularities.
Hand polishing the dies of gold medals and coins by hand is an essential step to ensure that the minted product will be of the highest quality precise, accurate, and pleasing to the eyes. It significantly improves the final product's appearance, consistency, and durability.

How Are Gold Blanks Being Fed Into Coin Presses, And Stamped Under High Pressure During Minting?
During the process of minting, gold blanks have to be loaded into coin presses and stamping at high pressure in order to create finished awards or coins. Here's the overview of steps involved in loading blanks.
In a feeder system linked to the press, the gold blanks have already been prepared and quality-tested. This feeder system ensures that there is a constant supply of blanks to the machine.
Feeding Blanks in the Press
The feeder system guides the blanks one after another into the chamber for striking of the coin press. This allows for precise positioning of the blanks.
Alignment and Positioning
In the press, the blanks are aligned and positioned in the striking chamber making sure that they are perfectly centered and oriented to allow for the stamping process.
Striking under High Pressure
The coin press has two dies: one stationary and the other one moves. The stationary coin die provides negative images of the coin's design. While the moving die is used as a hammer to hit the blank, the stationary die also has the positive impression.
The moving die transfer the design of the blank onto its surface using a lot of force. The pressure of the dies creates the design, as well as the raised relief.
The repetition of striking is not required.
To create a clearer image or a more distinct design, multiple strikes are often used on higher-quality coins and medals, especially proof editions. Each strike improves the design of the surface of the coin.
Ejection and Collection
After being struck and minted, the medals or coins created are taken from the presses. They then are collected in containers and trays. The stamped designs are inspected for quality and ensure they are in line with the specifications.
Post-Processing-
If the mint specifies it, they may also apply additional processes for edge lettering, reeding the edge, or post-strike procedures.
The high pressure of stamping imparts the desired designs onto the gold blanks, changing them to finished coins or medals that are ready for circulation, collections, or commemoration. It is essential to be precise, since even a slight variation in the pressurization or alignment of the gold-plated blanks may affect the quality and look of the final product.
