How And Why Is The Model Of A Plaster Scanned In Order To Create A 3d Digital Model For Gold Coins Or Medals?
Scanning a maquette of gold medals and coins requires specialized equipment. It records all dimensions, details, and physical features of the model. Digital reproductions are used for various purposes throughout the manufacturing process.
3D Scanning Technology - High-resolution 3D scanners can be used to record the physical dimensions and specifics of the model. The scanners employ various techniques including laser scanning or structured light, to take precise measurements and the geometry.
Surface Information Capture- The scanner emits laser or light beams on the model's surface. The reflections or distortions caused by these beams are recorded by the scanner, capturing the model's surface information.
Data Collection - As it moves along the surface of the plaster models, the scanner gathers an enormous amount of information points. These data points are utilized to create a digital model of the model including its contours, geometry, details, etc.
Conversion into 3D Model. Specialized software reconstructs information from the collected data into a 3D representation. This model resembles the physical dimensions and features of the maquette.
Why do we need to create a Digital 3D Model
Precision and Replication Digital 3D models permit exact replication of the physical model's specifications and dimensions. This ensures that the final gold coins as well as medals are designed to match the design intended.
Digital models permit easy adjustment or reworking. Designers can modify the design without altering the maquette made of plaster.
Compatibleness of Digital 3D Models with Manufacturing Processes. Digital 3D model are compatible with a variety of manufacturing processes, including CNC manufacturing.
Digital 3D models serve as a document for the design. They can be stored digitally for future reference, reproduction or for historical documentation.
By scanning a plaster model and creating an accurate digital 3D replica, manufacturers and designers are able to reduce production time, increase accuracy, and utilize advanced manufacturing technologies to produce gold-plated coins and medals with precision.

What Is The Reason Why Dies Used To Strike Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
The process of forming a vacuum for dies in striking gold coins or medals involves making the dies subject to high temperatures and controlled environments in a vapor furnace. This is a brief description of the vacuum-hardening process.
It is essential that the dies used to strike medals and coins are completely free of any contamination and residues.
Injecting Vacuum Furnace-
Die dies can be inserted into a vacuum oven, that creates a vacuum within the heat-treatment area.
Evacuation from Air-
Vacuum furnaces draw air out of chambers, resulting in an oxygen-free space. This stops oxidation and provides uniform heating.
Heating Phase
The furnace has to be heated to a temperature needed for hardening the dies. The temperature is determined by the material that is used and the way it will be shaped.
Soaking at High Temperatures-
The dies must be held at a high temperature for a certain duration to allow the material to attain and maintain its desired hardness.
Quenching or Cooling
Utilizing specialized techniques using specialized techniques, dies are swiftly cooling down or being quenched following the soak process. The rapid cooling process can help to ensure the desired level of strength and hardness of the steel.
Tempering (Optional)Tempering (Optional)
In some cases the tempering process is a part of the hardening process. Tempering involves reheating dies to a lower temperature, which helps relieve internal stresses and improve the toughness of the die while maintaining its hardness.
Quality Control and Inspection
To make sure they meet the specifications for strength and hardness the dies that are hardened undergo an extensive inspection and quality check.
Post-Treatment Handling-
Die dies are polished or coated, and used to strike coins or medals.
The vacuum hardening method increases die durability and wear resistance and also the life span of dies used to strike gold or silver coins and medals. This process creates a controlled atmosphere that is free of contaminants from the atmosphere to guarantee consistent and reliable hardening. It also contributes to the quality of the finished product.

What Are The Different Ways That Gold Coins Or Medals Are Coated In Order To Safeguard Them?
Gold coins and medals may undergo coating treatments for different reasons, such as protection, improvement of appearance or to create specific aesthetic effects. These are the various kinds of coatings used.
Clear Protective Coating (Varies)Clear protective coating, such as lacquer or a specialized polymer can be used to protect the surface against oxidation, tarnishing, or scratches. The coating keeps the original appearance of the coin or medal and shields the base metal.
Enhancement of Appearance
Gold Plating or Gilding- Gold medals or coins may undergo gilding or gold plating processes in which the thin layer of gold is sprayed on the surface. This gives the coin or medal a more luxurious, lustrous surface.
Aesthetic Aspekte
Antique or Patina finishes- Chemical treatments or coatings that are specialized are used to create an antique or patina finish. This process creates the appearance of a surface that is aged and aged and oxidized.
Colorization / Coloring – In certain cases the hue of specific areas on a coin, medal, or another item can be achieved through the use of specialized coatings and enamels. The purpose is to improve design elements, produce contrast, and enhance the visual appeal.
Anti-Tarnish Coatings-
Anti-Tarnishing Solutions - These solutions or coatings can be utilized on medals and coins with intricate designs, or are prone to tarnishing. The coatings stop oxidation and discoloration of metal surfaces over time.
Specialized Coatings for Security or Identification
UV-Reactive Coatings. Certain coins and medals are coated with special coatings, which react with UV light and reveal hidden or encrypted components. They are utilized for security and authentication purposes.
Selective Coatings for Contrast
Removal of Selective CoatingsIn some instances coatings are removed selectively, from certain areas of the coin or a medal, to create contrast, between coated and polished surfaces, highlighting the design elements.
Each coating process serves a specific purpose whether it's to shield the metal, improve its appearance, produce certain aesthetic effects, or even add security features.
