What Is The Reason Why Gold Coins Or Medal Dies Undergo The Process Of Hardening By Vacuum?
Vacuum hardening is a process that involves exposing dies high temperature and controlled environment in furnaces. Here's a brief outline of the vacuum hardening procedure used for die preparation and Cleaning-
It is vital that the dies used to strike medals and coins are completely free of any dirt and other contaminants.
Moving into vacuum Furnace
The dies will be placed in a vacuum chamber that is a specially designed heat-treatment room that can create vacuum.
Evacuation from the Air
The vacuum chamber is made by eliminating air from the chamber and creating an environment controlled and completely free of oxygen. This ensures uniform heating and prevents oxidation.
Heating Phase
The furnace is preheated to the required temperature for the hardening of dies. The temperature range is determined by the material type and the process of hardening.
Soaking in high temperatures
The dies will be kept at an elevated temperature for the exact duration needed to make sure the material attains and keeps the required hardness.
Quenching or Cooling
After the soaking, dies need to be quickly cooled by specialized methods. This fast cooling process assists in locking the desired hardness into the material.
Tempering is an option
In certain cases, a tempering process follows the hardening process. The dies are reheated at a lower temperature to ease internal stress and increase toughness, while maintaining hardness.
Quality Control and Inspection-
Hardened dies are subjected to thorough quality inspections and checks in order to meet the specifications for strength, hardness and dimensional tolerances.
Post-Treatment Handling-
When the process of hardening by vacuum is completed The dies can undergo further procedures like polishing or coating before they are used in the coin or medal striking process.
The method of vacuum hardening improves die durability and wear resistance and also the life span of the dies used to create silver or gold coins as well as medals. This procedure, which creates an environment that is free of airborne contaminants, guarantees that dies are consistently hardened and consistently, enhancing both the quality and longevity of the products.

What Makes It Possible To Create Certain Finishes Or Textures, Such As Matte Or Textured Surfaces?
Sandblasting is a method that is used to create certain textures or finishes that include matte or textured surfaces, on gold coins or medals. The procedure of Sandblasting is explained.
Surface preparation- The coin, medal or other item is placed inside an enclosed chamber or cabinet equipped with a nozzle that's connected to compressor. This chamber can be sealed to keep the abrasive substance employed during the process.
Abrasive Material Select- Abrasive particles like glass beads, aluminum oxide, silica carbide and sand are launched at high speed on the surface.
High-Pressure Propulsion: The abrasive particles are pushed onto the surface by compressed air or a different high-pressure system. The finish and texture of the surface is dependent on the force and velocity that the particles strike the surface.
Texture creation. The effect of abrasives on a surface alters the topography of the surface to create a textured, matte finish. This technique is employed to siftly roughen certain regions or create an even texture over the entire surface.
Sandblasting is controlled by the intensity, duration and the angle of application. This permits different textures and finishes. Different abrasives can be used to create different effects.
Sandblasting is a reason why it's done
Texture variations- Sandblasting permits the creation of different textures or surfaces such as mattes, frosted or even grainy surfaces. This creates visually appealing features and distinctive characteristics for the coins or medals.
Aesthetic Enhancement: Sandblasting can alter the appearance of the surface, decreasing the shine and diffusing light reflection. This may enhance the appearance of the medal or coin. Matte finishes can, for instance, highlight particular design elements since they minimize the glare.
Anti-Glare Properties - Matte or textured surfaces produced through sandblasting can help reduce reflections and glare. This makes the medals or coins more visually attractive and more enjoyable to look at without unwanted light interference.
Contrasting Elements in Design- Sandblasting is employed to create contrast between the areas that are polished or textured on coins or a medal. This can be done to highlight specific design elements or increase the depth and dimension.
Sandblasting is a great way to personalize and make distinctive designs. It allows you to express yourself artistically and produce coins and medals in various styles and textures.
