Why Do Gold Coin Or Medal Dies Go Through A Process Of Vacuum Hardening?
Vacuum hardening is a procedure that involves exposing dies extreme temperatures and a controlled environment in a furnace. This article will provide an overview of the process of vacuum hardening of dies.
To make dies that will be used to create the coins or medals, they need to be clean and free of any residues or contaminants.
Incorporating the load into a vacuum furnace
Die dies are placed in the vacuum chamber.
Evacuation from Air
Vacuum furnaces eliminate air from chambers, creating a non-oxygen environment. This can prevent burning while ensuring an even heat treatment.
Heating Phase
The furnace is then heated to the desired temperature to solidify the dies. The temperature depends on both the material that is used and the way it will be cured.
Soaking with High Temperatures
The material is allowed to achieve the desired hardness, and the metallurgical structure is created.
Cooling or quenching
After the soaking period after which the dies are cool or quenched with specialized methods. This rapid cooling process ensures the desired toughness and hardness of the metal.
Tempering (Optional)-
In some instances the tempering process occurs after the hardening stage. Tempering is the process of heating dies to a lower temperature to ease internal tensions and increase durability.
Quality Control Inspection
Dies with hardened material must undergo rigorous quality control and inspections to ensure they achieve the desired hardness, strength or dimensional tolerances.
Post-Treatment Handling-
After the process of vacuum hardening is completed, the dies may undergo additional processes such as polishing or coating prior to being utilized in the coin or striking process.
The process of vacuum hardening increases the durability of dies and wear resistance and also the life span of the dies used for striking silver or gold coins and medals. This process creates a controlled atmosphere that is free of contaminants from the atmosphere to ensure a consistent and reliable process of hardening. It also contributes to the quality of the finished product.

Why And How Are Certain Surfaces Or Textures That Resemble Matte Or Textured Surfaces Achieved Through Sandblasting?
This method is used for achieving specific textures or finishes like matte patterns, textured, or even textured surfaces on the surface of medals or coins. Here's how and why this method is utilizedProcess of Sandblasting
Surface Preparation The coin is put in a cabinet or a chamber equipped with an air compressor as well as a spray nozzle. The chamber is usually enclosed to contain the abrasive material that is used in 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 with high velocity.
High-Pressure System - The abrasive powders are propelled on the surface using compressed air, or by other high-pressure systems. The texture of the surface is produced through the force and speed of the particles.
Texture Creation. The force of an abrasive surface changes the surface topography creating a textured matte finish. This can be used either to create an even surface or create rough textures in specific areas.
Controlled application- Sandblasting is controlled by intensity duration, duration and angle of application. This permits different textures and finishes. Different abrasives are employed to create different effects.
Sandblasting - Why it is done
Texture variation- Sandblasting can create a variety and finishes such as smooth, grainy, frosted or surface textures. This can add visual interest to medals or coins.
Aesthetic Improvement- Sandblasting changes surface appearance. It diffuses light reflections and reduces the shine. This enhances the visual appeal of a coin or a medal. Matte finishes are a great way to highlight features of the design.
Anti-Glare Property: Sandblasting can create matte or textured surfaces that minimize reflections, glare and make the item more appealing.
Contrasting Design Elements. Sandblasting can create contrast between polished and the textured areas on the coin. It is a great way to emphasize specific design elements or create visual depth.
Sandblasting is a fantastic way to customize and create distinctive designs. It allows you to make your mark artistically and create coins and medals in various textures and finishes.
Sandblasting produces different textures and finishes on the surface of gold medals and coins. This increases their appearance, appeal and aesthetics.
