What Is The Reason Why Gold Coins Or Medal Dies Undergo Vacuum Hardening?
Vacuum hardening is a procedure that involves exposing dies to high temperatures and a controlled atmosphere in furnaces. This is a brief overview of how to vacuum harden dies.
To make dies that will be used to strike coins or medals, they should be clean and free from any contamination or residues.
Loading Vacuum Furnace
The dies may be put in a vacuum oven that creates a vacuum within the heat-treating area.
Evacuation via Airplane
The vacuum furnace eliminates the air in the chamber, creating a controlled vacuum, devoid of any oxygen or other gases. This is done to avoid oxidation as well as guarantee uniform heat treatments.
Heating Phase
The furnace needs to be heated to a temperature needed for hardening the dies. The range of temperature will be determined by the type of material and the hardening process.
Soaking with High Temperatures
The dies must be held at the highest temperature for a specified time to allow the material to attain and maintain its desired level of hardness.
Quenching (or Cooling)
After soaking and the dies are then cool or quenched with specialized techniques. The fast cooling process is able to lock in the required strength and hardness in the material.
Tempering (Optional).
In certain circumstances the process of tempering can occur as a result of hardening. Tempering is the process of heating dies up until they reach a temperature that is lower to relieve stress while maintaining their toughness.
Quality Control and Inspection
The molds that are hardened are examined and tested to make sure that the dies are in compliance with the requirements.
Post-Treatment Handling-
Die dies are then processed further including coating or polishing, prior to being used for the coins or medals.
The method of vacuum hardening improves die durability and wear resistance as well as the lifespan of the dies used to create silver or gold coins and medals. In ensuring a safe and free of contaminants it provides an efficient and consistent method to ensure that the dies are hardened.

How And Why Are Certain Finishes, Like Texture Or Matte Surfaces Created Using Sandblasting?
This technique can be used to give matte or textured effects on gold-plated coins and medals. The procedure of Sandblasting is explained.
Surface preparation. The medal or coin is placed inside a chamber with an air-compressor connected nozzle. The chamber is typically enclosed to contain the abrasive material that is used to prepare the surface.
Abrasive material selection- High speed propulsion of fine particles of abrasive abrasives like silicon carbide or sand or glass beads, and aluminum oxide onto the surface.
High-Pressure: The abrasive grains are driven to the surface with compressed air or using another high-pressure equipment. The force and speed that the particles encounter the surface produce the desired finish or texture.
Texture creation. The force of an abrasive surface alters the topography of the surface to create a textured, matte finish. This technique allows you to roughen certain areas or to create a texture that's consistent across the surface.
Controlled Application- Sandblasting may be controlled in terms of intensity the duration, angle, and intensity of application to achieve varying textures or finish. Different abrasives and pressure levels yield different results.
Sandblasting - Why it is done
Texture Variation Sandblasting is an excellent technique to create various designs or textures on medals and coins like glossy or frosted surfaces. It gives the appearance and unique features.
Aesthetic Enhancement: Sandblasting changes the surface appearance, diffusing light reflection and diminishing shine. This can increase the coin's or medal's visual appeal. Matte finishes, for instance, may highlight specific designs by reducing the reflections and glare.
Anti-Glare Property: Sandblasting can create matte or textured surfaces that minimize reflections, glare and makes the medal or coin more attractive.
The contrast of design elementsSandblasting can produce contrast between polished and textured components of a coin or medal. This can help to highlight particular features or to add visual depth.
Sandblasting allows for customization that includes artistic expression and the creation of unique medals or coins with finishes or textures customized to meet specific design requirements.
Sandblasting can create various textures and finishes on the gold medals and coins. This improves their overall appearance, appeal, as well as aesthetics.
