Why Do The Dies Used For Striking Gold Medals Or Coins Undergo The Process Of Hardening By Vacuum?
The process of forming a vacuum to create dies that strike gold medals or coins involves making the dies subject to high temperatures and controlled environments in a vapor furnace. Here's a brief overview of the dies for vacuum hardening.
When creating dies to be used for striking coins or other medals, it's essential that they are free of any residues or contaminants.
Injecting Vacuum Furnace-
The dies can be placed in a vacuum oven that creates a vacuum within the heat-treating area.
Evacuation of Air-
The vacuum furnace removes the air inside the chamber, creating an uncontrolled vacuum, free of oxygen and other gasses. This helps to prevent the oxidation process while also ensuring a uniform heat treatment.
Heating Phase
The furnace is then heated to the desired temperature for the hardening of dies. The range of temperatures is determined by the specific material used and the process of hardening.
Soaking at High temperatures
The dies stay at high temperatures for a specific period of time, which allows the material to reach the hardness that is desired and to maintain metallurgical structures.
Cooling and cooling as well as quenching
Following the soaking process and the dies are then cool or quenched with specialized techniques. Rapid cooling helps to lock in the desired hardness and strength in the metal.
Tempering (Optional).
In certain instances, a tempering step occurs following the stage of hardening. Tempering is the process of reheating dies at a low temperature to ease internal tensions and increase durability.
Quality Control and InspecQuality Control and Inspec
Dies with hardened material must undergo rigorous quality inspections and control to ensure they achieve the desired hardness, strength or dimensional tolerances.
Post-Treatment Handling-
After the process of vacuum hardening is finished Die dies are then subject to additional processes such as polishing or coating prior to being employed for the coin or medal striking process.
Vacuum hardening enhances the life as well as the durability, and wear resistance of dies which are used to make gold coins or medals. By ensuring a controlled and free of contaminants it provides a consistent and reliable way to ensure that the dies are hardened.

What Is The Reason And How Is It Possible To Achieve Certain Finishes Or Textures, Like Textures Or Matte Surfaces?
This method is used for creating specific textures or finishes like matte, textured, or patterned surfaces, on the surface of medals or coins. Why and how do you use this technique?
Surface preparation- The coin, medal or other piece of material is placed in an enclosed compartment or cabinet equipped with the nozzle which is connected to a compressor. This chamber may be enclosed to contain the abrasive material that is used during the process.
The coin or medal is then sprayed with an abrasive substance, which can comprise glass beads, sand silicon carbide or aluminum oxide.
High-Pressure System- The abrasive particles are driven onto the surface by compressed air, or by other high-pressure systems. The finish and texture of the surface depends on the force and speed with which the particles impact the surface.
Texture Creation. The force of abrasives on a surface alters its topography to create a textured, matte finish. This method lets you roughen specific areas or create a texture consistent across the surface.
Sandblasting that is controlled- Sandblasting can be controlled by intensity, duration, and angle of application in order to create different textures or finishes. Different abrasives are used to achieve different results.
Sandblasting is a necessity?
Texture Variation Sandblasting is a fantastic way to create different texture or finish on coins and medals, including glossy or frosted surfaces. It gives the appearance and distinctive features.
Aesthetic Enhancement - Sandblasting alters the look of the surface, reducing the shine while also diffusing light reflection. This may enhance the appearance of the medal or coin. Matte surfaces, such as ones that cut down on glare may highlight particular design features.
Sandblasting properties to reduce glare - Through using sandblasting techniques, a matte or textured surface can be produced. This helps reduce glares as well as reflections. The coins and medals look more appealing and clearer to view without light interference.
Contrasting Elements in Design - Sandblasting can be used to create contrasts between areas that are polished or textured on a coin or medal. It can be used to highlight specific design elements and/or give dimension and depth.
