Why Do The Dies Used For Striking Gold Medals Or Coins Undergo Vacuum Hardening Processes?
Vacuum hardening refers to a process which involves exposing dies to high temperature and controlled environment in a furnace. Here's a quick guide on how to make dies harder by vacuum.
When creating dies to be used for striking metals or coins, it is crucial that they are clean of contamination or residues.
Loading Vacuum Furnace
The dies are then placed inside a special heat-treating chamber that can create an atmosphere of vacuum.
Evacuation of Air-
The vacuum oven eliminates any air in the room and creates a safe environment without oxygen as well as other gases. This eliminates oxidation, and ensures uniform heat treatment.
Heating Phase-
The furnace then gets heated up to the desired temperature for hardening dies. The range of temperature is determined by the material type and the process of hardening.
Bathing in high temperatures
The dies are kept at a high temperature for a specified time which allows the material to attain and keep the desired hardness and the metallurgical structure.
Quenching or cooling
With the help of special techniques using specialized techniques, dies are swiftly cooling down or being quenched following the soak process. Rapid cooling assists in locking the desired strength and hardness in the metal.
Tempering is an option
In some instances, a tempering step is performed after the hardening stage. Tempering involves reheating the dies to a lower temperature, which helps alleviate internal stress and increase toughness while maintaining toughness.
Quality Control and Inspection-
Hardened dies must pass thorough quality control and inspections to ensure they achieve the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
Die dies are then later subjected to further treatment including polishing or coating prior to being used for the coin or medal striking.
Vacuum hardening increases the longevity, toughness and wear resistance of the tools that are used to create gold coins or medals. This procedure creates a controlled environment free of atmospheric contaminants to guarantee consistent and reliable hardening. This also enhances the overall quality of the minted product.

How Do Gold Coins And Medals Receive Protective Coatings?
Coating gold medals or coins is used for various reasons. It is for protection as well as improving the appearance, or creating a certain aesthetic appearance. Here are the various coating methods that are used to protect Coatingsfor protection.
Clear Protective Coating (Varies)Clear protective coating, such as lacquer or a specially-formulated polymer is a coating that can be applied to protect the surface against oxidation, tarnishing, or scratches. This coating helps maintain the original appearance of the coin and protects any metal underneath.
Enhancement of Appearance
Gold plating (or gold plating)- A thin layer or gold may be applied on the surface of gold coins or medals. This improves the coin's or medal's appearance and gives it a more shiny and a luxurious appearance.
Aesthetic effects
Antique finishes and patinas can be created by using chemical treatments or coatings. This creates a aged or oxidized appearance to the surface. It adds dimension and character to your design.
Colorization or ColoringSometimes, specific parts of the medal or coin are colored using specialized coatings or enamels in order to emphasize design elements, create contrast, or add visual interest.
Anti-Tarnish Coatings-
Anti-Tarnish Solution – If the medal or coin is intricately designed, or has specific areas are prone to tarnish, you may wish to apply anti-tarnish solutions. The coatings keep the metal from discoloration and oxidation through time.
Specialized Coatings For Security Or Authentication
UV-Reactive Coatings. Certain metals and coins have a special UV-reactive coating which reacts to UV radiation. It can reveal hidden components such as encryption or security codes.
Selective Coatings to Contrast
Selective Coating RemovableIn certain instances, the coatings of coins or medals are removed in a specific manner to provide contrast when polished and coated surfaces.
Each method serves a specific purpose, be it to safeguard metals, enhance appearance, create certain aesthetic effects, or add security. These coatings can have a major impact on the durability and appeal of gold-plated coins and medals. They also increase their value.
