Why Do Dies Used To Strike Gold Medals Or Coins Undergo Vacuum Hardening Processes?
The method of vacuum hardening is employed in the making of gold medals or coins. It involves heating the dies at high temperatures, and exposing them to controlled environments within a vacuum. Here's a brief overview of the dies for vacuum hardening.
Diets used to strike medals or coins are clean and free of contaminants.
Moving into the vacuum furnace
The dies are placed in a specially designed heat-treating chamber which can generate an atmosphere of vacuum.
Evacuation of Aircraft
The vacuum furnace eliminates the air inside the chamber to create a controlled vacuum, devoid of oxygen or other gases. This stops oxidation, and also ensures a uniform heating.
Heating Phase
The furnace is then heated to the temperature required for hardening dies. Temperatures can vary based on the material used and the process of hardening.
Drinking at high temperatures
The dies remain at the higher temperatures for a certain time, which allows the material the reach the desired hardness level and also to preserve metallurgical structures.
Cooling or quenching
Following the soaking phase after which the dies are rapidly cooled using specialized techniques. The rapid cooling process helps to lock the desired hardness in the metal.
Tempering (Optional).
In some instances, the hardening process is followed by a tempering procedure. To improve the toughness and relieve internal stress, dies could be reheated at a lower temperature.
Quality Control and Inspection
To ensure that they meet specifications for strength and hardness Die dies that have been hardened go through an extensive inspection and quality test.
Post-Treatment Handling-
The dies, following the process of vacuum-hardening is completed, can be further processed, such as polishing and coating before they are utilized in the coin striking or medal striking processes.
The process of hardening by vacuum increases the strength, durability of the dies, their wear resistance and the life of the dies used to create gold coins or medals. In creating a controlled, safe environment free from atmospheric contaminants This process guarantees the consistent and reliable hardening of dies, thereby enhancing the longevity and quality of the finished products.

How Do You Get Matte Or Textured Finishes Through The Process Of Sandblasting? And How?
This method can be used to creating specific textures or finishes that include matte, textured, or patterned surfaces, for coins or medals. The process of Sandblasting is explained.
Surface Preparation The coin is put in a cabinet or a chamber fitted with an air compressor as well as the spray nozzle. This chamber is often sealed to contain the abrasive materials used during the process.
Abrasive material selection- High speed propulsion of small particles of abrasive materials, such sand or silicon carbide or glass beads, and aluminum oxide onto the surface.
High-Pressure-The abrasive grains are propelled to the surface with compressed air or by another high-pressure system. The finish or texture is determined by the force and speed at which particles impact the surface.
Texture Creation - The impact of the abrasive particles onto the surface results in a textured or matte appearance, by altering the surface's topography. This can be used either to create a smooth surface or to create a rough texture in specific areas.
Controlled Application- Sandblasting can be controlled by intensity the duration, angle, and intensity of application to produce different textures or finishes. Different abrasives, pressure levels and abrasives produce different results.
Sandblasting - The reason it's done
Texture variations- Sandblasting permits the creation of different surface textures, or even mattes, frosted or grainy surfaces. This creates visually appealing features and distinctive characteristics to the coins or the medals.
Aesthetic Improvement- Sandblasting alters surface appearance. It diffuses light reflections and reduces the shine. This increases the visual appeal of a medal or coin. Matte finishes, for example can highlight certain features of the design by reducing glare.
Anti-glare properties - The matte or textured finishes that are created by sandblasting decrease reflection and glare, making metals and coins more pleasant to look at and more attractive.
Contrasting Elements in Design - Sandblasting is used to create contrasts between areas that are polished or textured on a coin or medal. This is done to highlight certain design features or increase the depth and dimension.
Sandblasting is customizable to produce distinctive textures or designs.
Sandblasting produces various textures and finishes on the gold coins and medals. This improves the overall appeal, appearance and aesthetics.

How Does Gold Get Into The Coin Presses, And Then Stamped Under High-Pressure During Minting?
During the coining process the gold blanks are loaded into coin presses under intense pressure. Then, they are stamped to produce finished medals or coins. This is a brief overview of loading blanks.
The loading of gold blanks into a feeder connected to the coin press takes place after they have been prepared, examined and graded. The feeder system is responsible for maintaining a continuous flow of blanks to the machine.
Feeding Blanks Through the Press
The system of feeding is designed to guide the blanks one at a time into the striking chamber. This allows for precise positioning of the blanks.
Alignment and Positioning
Within the press, the blanks are aligned and placed in the chamber for striking making sure that they are perfectly centered and oriented for the stamping process.
Strumping in High Pressure
The coin press uses two dies: one stationary and the other one moves. The stationary coin die gives negative images of the design. While the die that moves is used as a hammer to strike the blank, the stationary die also contains the positive impression.
The moving die transfers the design of the blank to its surface with a great deal of force. The pressure exerted by the dies stamps the design on the blank and creates the relief that is raised as well as specifics on the coin or medal.
Repeated Striking (Optional)-
To produce an image or design that is clearer and better defined, multiple strikes may be applied on premium coins or editions of collectibles. Each strike helps to refine the surface characteristics of the coin or medal.
Ejection and Collection
The coins or medals will be released and placed into containers or trays once they've been struck. They are then inspected to ensure quality control and make sure that the designs are in line with all standards and criteria.
Post-Processing-
If the mint requires it, they could apply additional procedures, such as edge lettering, reeding of the edges, or post-strike treatment.
The process of stamping gold blanks using high-pressure is essential as it transfers the desired design to the blanks of gold. Then, they are transformed into finished coins or medals ready for collection, circulation or commemoration. This process demands precision as any deviations in pressure or alignment could alter the appearance and performance of the end product.
