Why Is Vacuum Hardening Used On Dies To Make Gold Coins Or Medals?
To make dies harder for gold coins or medals, they're subjected to temperature control in an oven that is a vacuum. This is a brief overview of how to harden dies using vacuum.
It is crucial that dies used for striking medals and coins are completely clean, free of dirt and other contaminants.
Injecting Vacuum Furnace-
The dies will be put in a vacuum chamber, which is a specialized heat-treatment room that can create vacuum.
Evacuation with Airplane
The vacuum chamber is created by removing air from the chamber and establishing an atmosphere that is devoid or oxygen. This stops oxidation, and provides uniform heat treatment.
Heating Phase
The furnace is heated to the appropriate temperature for the hardening of dies. The temperature will depend on the material being used and the method by which it will be hardened.
Soaking with High Temperatures
The dies have to be kept at a high temperature for a specific duration to allow the material to reach the desired hardness.
Quenching (or cooling)
After soaking and the dies are then cooling or quenched by using special techniques. The rapid cooling helps the metal to achieve the desired level of hardness.
Tempering (Optional).
In certain cases the tempering process is a part of the hardening process. Tempering involves reheating dies at a low temperature to ease internal tensions and increase durability.
Quality Control Inspection
The molds that are hardened are examined and tested to make sure that the dies are in compliance with the requirements.
Post-Treatment Handling-
The dies will be subjected to further processing including coating or polishing, prior to being used for strike of the coin or medal.
Vacuum hardening improves the durability, durability, and wear resistance of dies that are used to create gold coins or medals. This process, which creates an environment free of airborne pollutants, assures that dies are hardened consistently and safely, which improves both the quality and the longevity of the product.

How And Why Are Some Finishes Or Textures Like Matte Or Textured Surfaces Achieved Through Sandblasting?
This method can be used to achieving specific textures or finishes, such as matte and textured surfaces on the surface of medals or coins. This is how and why it is used.
Surface preparation- The coin, medal or other object is put in an enclosed compartment or cabinet that has the nozzle which is connected to compressor. Abrasive materials are usually contained inside this chamber.
Abrasive Materials Selection - At high speeds, fine particles of abrasive substances like silicon carbide (sand), glass beads, or aluminum oxide are propelled on the surface of the coin or medal.
High-Pressure Propulsion- The abrasive particles are propelled onto the surface using compressed air or another high-pressure system. The texture of the surface is created by the force and speed of the particles.
Texture creation. The force of an abrasive on a surface alters the topography of the surface to create a textured, matte finish. This method can be used to create an even texture or roughen particular areas.
Controlled Application: Sandblasting intensity, duration, angle, and application can be controlled to produce different surfaces or textures. Different abrasives can create different results.
Sandblasting is utilized for a variety of reasons
Texture variation- Sandblasting may produce a variety of different textures and finishes like glossy, grainy, frosted or smooth surfaces. This adds visual interest to coins or medals.
Aesthetic enhancement- Sandblasting can change the appearance of the surface by diffusing light, and thus reducing shine. This may improve the appearance of a coin. Matte finishes, for example highlight specific particular design elements by reducing the reflections.
Anti-glare properties - The matte or textured finishes produced by sandblasting reduce reflection and glare, making metals and coins more pleasant to look at and more attractive.
Contrasting Elements in Design- Sandblasting can be used to create contrast between the areas that are polished or textured on coins or medal. This is done to emphasize certain features of the design or add dimension and depth.
Sandblasting offers a variety of customization options that allow for artistic expression and permits medals, coins, or other items to be designed with different specific textures or finishes to the design.
Sandblasting can create different finishes and textures on the surface of gold coins and medals. This improves their overall appearance, appeal, as well as aesthetics.

How Are Gold Blanks Put Into Coin Presses To Be Stamped Under Extreme Pressure While Minting?
In the process of minting, gold blanks must be loaded into coin presses, and stamped at high pressure to create finished awards or coins. This article will provide an overview of the steps that are involved in loading blanks
A feeder system is attached to the coin press. This system loads gold blanks that have been prepared and checked for quality. The feeder system is responsible for ensuring that blanks are continuously flowed into the coin press.
Feeding Blanks into the Press
The feeder system feeds the blanks into the chamber for striking in the coin press one at a. This allows for precise positioning of the blanks.
Alignment and Positioning
The blanks are placed in the press, and then placed into the room for striking to ensure they are centered and perfectly placed to enable the stamping.
Striving Under Pressure
A coin press applies pressure on gold-plated blanks with two dies, one stationary, the other moving. The stationary die leaves a negative impression on the design of the coin while the moving one is the hammer which strikes the blank.
Die dies hit the blank with a lot of force, which transfers the design onto the surface. The dies' pressure imprints the designs, resulting in the raised reliefs and details of the coin or medal.
The repetition of striking is not required.
In order to create an image or design that is more sharp and more clear, several strikes may be applied on high-quality coins or collectible editions. Each strike enhances the finer details on the outside of the coin.
Ejection and collection
After they have been struck, the freshly minted medals or coins are removed from the press and collected in trays or containers. They are then inspected to ensure quality control and ensure that stamped designs meet all standards and criteria.
Post-Processing-
In addition to edge letters and Reeding based on design specifications or mint specifications, certain coins or medals will undergo post-strike treatments or other procedures.
The process of stamping under high pressure is essential because it imparts the desired design on the gold blanks, turning them into finished pieces of gold ready for use in collection, circulation, or even commemoration. This process requires precision because any variations in alignment or pressure can impact the appearance and quality of the end product.
