Why Does Vacuum Hardening Get Used On Dies Used To Make Gold Coins Or Medals?
The process of forming a vacuum for dies in striking gold medals or coins requires placing the dies in high temperatures and controlled environments in a vacuum furnace. Here's an overview of the procedure for die preparation and Cleaning.
To create dies to be used to strike coins or medals, they must be clean and free from any contamination or residues.
Loading into Vacuum Furnace-
The dies are put into a vacuum-environment chamber.
Evacuation Air
The vacuum chamber is made by eliminating air from the chamber and establishing a controlled environment that is devoid or oxygen. This ensures uniform heating, and also prevents the oxidation process from occurring.
Heating Phase-
The furnace is heated to the appropriate temperature for hardening of dies. The temperature range depends on the particular material and the processing for hardening.
Soaking in high temperatures
The dies are held at the elevated temperature for a specific time, allowing the material to reach and keep the desired hardness and metallurgical structure.
Quenching or Cooling
After soaking, the dies need to be quickly cooled with special methods. The rapid cooling process can help keep the desired toughness and durability of the metal.
Tempering is not required.
In certain cases, a tempering process follows the hardening process. Tempering is the process of heating dies to a lower temperature in order to relieve internal tensions and increase the toughness.
Quality Control and InspecQuality Control and Inspec
Dies that are hardened must go through rigorous quality inspections and control to attain the desired strength, hardness or tolerances.
Post-Treatment Handling-
The dies, following the process of vacuum-hardening is complete, could be further processed using polishing and coating before they are used in coin striking or medal striking process.
The process of forming a vacuum enhances the durability and wear resistance and life expectancy of the dies, which are used to create coins or medals. The process of hardening by vacuum is an efficient and reliable method to ensure that dies are hardened in a controlled, safe environment free of contaminants.

How And Why Are Some Types Of Finishes, Textures Or Textured Surfaces Achieved Through Sandblasting?
This method is used for achieving specific textures or finishes, such as matte patterns, textured, or even textured surfaces on the surface of medals or coins. This article explains what this technique is and how it is employed.
Surface preparation: The medal, coin or other piece of material is placed in an enclosed chamber or cabinet equipped with a nozzle that's connected to compressor. The chamber may be sealed to contain the abrasive substance that is used in the process.
Abrasive Materials Selection - At high speeds, tiny particles of abrasive substances, like silicon carbide (sand) glass beads, or aluminum oxide are propelled on the surface of the medal or coin.
High-Pressure: The abrasive grains are driven onto the surface using compressed air or by another high-pressure device. The finish and texture of the surface depends upon the force and speed at which the particles hit the surface.
Texture Creation. The force of abrasives on a surface changes the surface topography to create a textured, matte finish. This process can be used to create an even texture or roughen specific areas.
Controlled application- Sandblasting is controlled by intensity duration, duration and angle of the application. This permits different textures and finishes. Different abrasives, pressure levels and abrasives can produce different results.
Sandblasting can be used for many reasons.
Texture variation - Sandblasting can produce a variety of different textures and finishes, including smooth, grainy, frosted or textured surfaces. This adds visual appeal to medals or coins.
Aesthetic Improvement- Sandblasting changes surface appearance. It helps diffuse light reflections and reduces the shine. This improves the visual appeal of a coin or medal. Matte surfaces, such as those that reduce glare, can highlight specific design details.
Anti-Glare Properties- Matte or the textured surfaces that are created through sandblasting can reduce reflections and glare, making the medals or coins more visually appealing and easier to view without interference from light.
Sandblasting creates contrast in design Elements - Sandblasting creates a contrast between polished and texture areas of the medal or coin, which emphasizes particular design elements or creating visual depth.
Customization and Creativity- Sandblasting offers customization options, allowing for artistic expression and the creation of medals or coins with unique textures or finishes customized to meet specific design specifications.
Sandblasting is a versatile technique used to create various surface finishes or textures on gold-plated coins and medals which contribute to their aesthetics, appearance, and overall design.

How Are Gold Blanks Being Fed Into Coin Presses, And Stamped Under The Pressure Of High During Minting?
When minting is completed gold blanks are loaded into coin presses and stamped under extreme pressure to make them into finished pieces of gold or coins. Here's a quick overview of the process of loading blanks.
The gold-colored blanks are inserted in the feeder system that is connected to coin presses. This feeder system ensures an ongoing supply of blanks for the machine.
Feeding Blanks to the Press
The feeding system was designed to guide the blanks one-by-one into the striking chamber. The feeder system makes sure that each blank is precisely placed to allow for stamping.
Alignment & Positioning
Inside the press, blanks are aligned and placed in the striking chamber, ensuring that they are perfectly centered and aligned to be used for stamping.
Striking Under Pressure
The coin press presses the gold blanks at high pressure using two dies, one stationary and another moving. The stationary die is the negative design impression and the die that moves is known as the hammer.
The moving die transfer the design from the blank onto its surface with considerable force. The dies pressurize the design and create relief raised on the coin or medal.
Repetition of Striking Is Optional
Multi-strikes can be applied for more expensive coins or medals, such as proofs or collectors' editions. This results in an improved and clearer appearance. Each strike increases the clarity on the surface.
Ejections and Collection
After being struck, newly-minted coins or medals are ejected from the press and collected in trays or containers. They are examined for quality control in order to ensure that the designs stamped meet the specifications and standards.
Post-Processing-
If the mint specifies the process, they can apply additional processes for edge lettering, reeding the edges, or post-strike treatment.
Stamping with high pressure etch the desired designs onto the blanks of gold, transforming them to finished coins or medals that are suitable for circulation, collections or for commemoration. This process demands precision, since any slight variation in alignment or pressure could affect the quality and appearance of the final item.
