What Is The Reason That Dies Used To Strike Gold Coins Or Medals Undergo The Process Of Hardening By Vacuum?
To make dies harder for gold coins or medals, they are subjected to controlled temperatures inside a vacuum oven. This is a brief description of the process for forming a vacuum.
It is vital that the dies used to strike medals and coins are completely clean, free of contamination and residues.
Loading in Vacuum Furnace
The dies are put into a vacuum-environment chamber.
Evacuation from Air
The vacuum furnace removes the air inside the chamber to create an uncontrolled vacuum, free of oxygen and other gases. This ensures uniform heating and prevents oxidation.
Heating Phase
The furnace is heated up to the desired temperature required for hardening the dies. The range of temperatures will be determined by the material type and the process of hardening.
Bathing in high temperatures
The dies are held at an elevated temperature for a specified time, allowing the material to achieve and retain the desired hardness as well as the metallurgical structure.
Quenching or Cooling
After the soaking process, dies have to be cooled quickly using specialized techniques. The rapid cooling helps the metal achieve the required hardness.
Tempering (Optional).
In some cases it is possible to temper after hardening. Tempering involves reheating the dies at a lower temperature in order to alleviate internal stress and increase the toughness of the die while maintaining its their hardness.
Quality Control and Inspection
Hardened dies must pass thorough quality control and inspections to ensure they achieve the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
Die dies are then processed further like polishing or coating, before being used for strike of the coin or medal.
The process of hardening by vacuum increases the strength, wear resistance, and lifespan of the dies used for striking gold medals or coins. This process, which creates an environment that is free of airborne contaminants, ensures that dies are consistently hardened and consistently, enhancing the overall quality and durability of the products.

What Are The Benefits Of Sandblasting Certain Kinds Of Textures Or Finishes, Like Matte Surfaces Or Textured Ones?
This method can be used to achieving specific textures or finishes, such as matte, textured, or patterned surfaces, on coins or medals. This technique is utilized to achieve a number of different reasons.
Surface preparation- The coin or medal is placed in the form of a cabinet or chamber with a nozzle connected to an air compressor. The chamber is typically covered to protect the abrasive material that is used during the process.
Abrasive Material Selection - Fine particles of abrasive materials, such as sand, silicon carbide, glass beads or aluminum oxide are propelled onto the surface of the medal or coin at high speed.
High-Pressure System - The abrasive powders are propelled on the surface by compressed air, or by other high-pressure systems. The force and speed at which the particles hit the surface produce the desired texture or finish.
Texture Creation - The impact of abrasive powders on the surface alters the topography, creating an appearance that is matte or textured. This method is used to selectively roughen some regions or create an even texture across the whole surface.
Controlled application- Sandblasting is controlled by intensity, duration and the angle of application. This allows for different textures and finishes. Different abrasives, pressure levels and abrasives produce different results.
The reasons for sandblasting
Texture variation- Sandblasting can produce a variety of different textures and finishes such as smooth, grainy, frosted or smooth surfaces. This adds visual appeal to medals or coins.
Aesthetic Enhancement - Sandblasting alters the appearance of the surface, reducing light reflection and reducing shine, which may enhance the medal's or coin's visual appeal. Matte finishes in particular, draw attention to particular design elements since they reduce the glare.
Anti-glare Property - Sandblasting creates smooth or matte surfaces that minimize reflections, glare and make the coin or medal more attractive.
Contrasting Design Elements. Sandblasting produces contrast between polished and the textured areas on the coin. It can be used to emphasize specific design elements or create visual depth.
Sandblasting can be personalized to create unique designs or textures.
Sandblasting is an ingenuous method that can be applied on gold coins in order to create different surface textures. It also enhances the overall look of the medals.
