Why Do The Dies Used To Strike Gold Medals Or Coins Undergo Vacuum Hardening Processes?
Vacuum hardening is a procedure which involves exposing dies to high temperature and controlled environment in the furnace. This is a brief description of the vacuum-hardening process.
When making dies that will be used to strike coins or other medals, it's essential that they are free of contamination or residues.
Loading into Vacuum Furnace-
Die dies are kept in the vacuum furnace. It is a specially designed heat-treating chamber that can create an atmosphere of vacuum.
Evacuation from the Air
The vacuum furnace draws air from the chamber, creating a controlled vacuum environment devoid of oxygen or other gases. This stops oxidation, and ensures uniform heat treatment.
Heating Phase
The furnace is heated to the ideal temperature required for hardening the dies. The range of temperature is determined by the type of material and the method of hardening.
Drinking at high temperatures
The material is allowed to reach the desired hardness, as well as the metallurgical structure is created.
Cooling and cooling as well as quenching
Following the soaking process after which the dies are cool or quenched with specialized techniques. Rapid cooling helps to lock the desired strength and hardness within the metal.
Tempering (Optional).
In some instances there is a process of tempering that follows the process of hardening. Tempering involves heating the dies up until they reach a temperature that is lower to ease stress and maintain the toughness.
Quality Control and InspectionQuality Control and Inspec
The dies that are hardened undergo rigorous quality tests and inspections to confirm that they meet the required toughness, hardness, and dimensional tolerances.
Post-Treatment Handling-
Die dies are then later subjected to further treatment like coating or polishing, prior to being used for the coins or medals.
The process of vacuum hardening increases the strength, durability as well as the wear resistance and life span of the dies used to create gold coins or medals. Through the creation of a controlled atmosphere free of atmospheric pollutants This process guarantees the consistent and reliable hardening of dies, thereby enhancing the durability and quality of the products that are minted.

How And Why Are Certain Surfaces, Such As The Matte Or Textured Surfaces, Achieved Through Sandblasting?
Sandblasting can produce textured or matte surfaces on gold coins and medals. Why and how is this method used?
Surface preparation - The coin or the medal is put into a chamber, cabinet or nozzle attached to an air compressor. This chamber is often sealed to contain the abrasive materials used in the process.
The coin or medal is then sprayed with abrasive substance, which can comprise glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure System- The abrasive powders are pushed onto the surface by compressed air, or other high-pressure systems. The force and speed that the particles encounter the surface will create the desired texture or finish.
Texture Creation. The impact of an abrasive surface alters its topography creating a textured matte finish. This method lets you roughen specific areas, or create a texture that is similar across the entire surface.
Controlled Application- Sandblasting can be controlled by intensity as well as duration and angle of application to produce different textures or the appearance. Different abrasives and pressure levels produce different results.
Sandblasting - Why it is done
Texture Variation Sandblasting is a fantastic method to create different designs or textures on medals and coins, such as glossy or frosted surfaces. It gives the appearance and distinct qualities.
Enhances the aesthetics of a surface - Sandblasting can alter the appearance of the surface and reflect light in a diffuse manner and even reduce shine. This will enhance the value of the coin or medal's aesthetic appeal. Matte finishes, for example, may highlight specific design elements by reducing the glare.
Anti-Glare - A matte surface or textured finish produced by sandblasting will reduce reflections and glare. This makes the medals or coins look more attractive, and also much easier to read, without unwanted light interference.
Contrasting Design ElementsSandblasting creates contrast between polished and textured areas of the coin or medal, emphasizing specific design features or giving the appearance of depth and dimension.
Sandblasting provides customization options that allow for artistic expression, and permits medals, coins, or other items to be designed with different distinct textures or finishes that are unique to the design.
Sandblasting is a new technique that can be used on gold coins to achieve various surface textures. It also improves the overall look of the medals.
