Why Do The Dies Used For Striking Gold Medals Or Coins Undergo Vacuum Hardening Processes?
The process of forming a vacuum to make dies for striking gold medals or coins requires making the dies subject to extreme temperatures and controlled conditions within a furnace that is a vacuum. Here's an overview of the vacuum hardening process for dies Preparation and Cleaning.
When preparing dies to be used for striking coins or other medals, it is important that they are free of residues or contamination.
Moving into Vacuum Furnace
Die dies can be inserted into a vacuum oven, which creates a vacuum in the area of heat treatment.
Evacuation from Air-
The vacuum oven eliminates all air from the chamber creating an environment free of oxygen and other gases. This ensures uniform heating, and also prevents oxidation.
Heating Phase
The furnace must be heated to a temperature necessary to harden the dies. The range of temperatures is determined by the particular material and the hardening process.
Bathing at high temperatures-
The dies are held at an elevated temperature for a specified time, allowing the material to reach and retain the desired hardness as well as metallurgical structure.
Quenching (or cooling)
Utilizing specialized techniques using specialized techniques, dies are swiftly cooling down or being quenched following the soaking process. Rapid cooling assists in locking in desired hardness and strengths in the steel.
Tempering (Optional)-
In some situations the process of tempering can occur as a result of hardening. Tempering is the process of heating dies up to a lower temperature in order to alleviate stress while preserving toughness.
Quality Control and Inspection-
The molds that are hardened are inspected and tested to ensure that the dies satisfy the requirements.
Post-Treatment Handling-
After the hardening process dies can be polished or coated before they are utilized in the coin or metal strike process.
The process of hardening by vacuum increases the strength, wear resistance, and lifespan of the dies used to create gold medals or coins. The process of vacuum hardening is a reliable and predictable method to harden dies in a controlled and safe environment free of any contaminants.

How Do You Get Smooth Or Matte Finishes Using The Process Of Sandblasting? And How?
This method can be used to making specific finishes or textures, such as matte and textured surfaces, for the surface of medals or coins. This method is used to achieve a number of different reasons.
Surface preparation: The medal, coin or other item is placed inside an enclosed chamber or cabinet that has the nozzle which is connected to compressor. The chamber can be enclosed to contain the abrasive material employed in the process.
The coin or medal is then sprayed with an abrasive material, which could comprise glass beads, sand silicon carbide or aluminum oxide.
High-Pressure System - The abrasive powders are pushed onto the surface with compressed air or other high-pressure systems. The speed and force with the rate at which particles are thrown onto the surface determines the texture or finish.
Texture Creation: The impact of the abrasive particles on the surface creates a matted or textured look by changing the topography of the surface. This process lets you roughen specific areas, or create a texture that's similar across the entire surface.
Sandblasting can be controlled in terms of intensity, duration, and angle controlled, resulting in different finishes or textures. Different pressure levels, abrasives and abrasives result in different outcomes.
The reasons for sandblasting
Texture Variation- Sandblasting permits to create diverse types of textures and finishes such as matte and frosted surfaces, which adds visual interest and unique particularities to the coins or medals.
Aesthetic enhancement- Sandblasting may change the appearance of the surface by diffusing light, and thus reducing shine. This may increase the coin's appeal. Matte surfaces, such as those that reduce glare, are able to highlight particular design elements.
Anti-glare properties - The textured or matte finishes created by sandblasting can reduce reflectivity and glare, which makes coins and medals easier to look at and more attractive.
Sandblasting Produces Contrasting Design Elements - Sandblasting creates a contrast between the texture and polished areas on the medal or coin, which emphasizes particular design elements or creating visual depth.
Customization and Creativity- Sandblasting offers customization options, allowing to express your creativity and artistic flair, as well as the creation of medals or coins with unique designs or textures that are customized to meet specific design specifications.
