What Is The Purpose Of A Plaster Model Scanned To Create A 3d Digital Model Of Gold Coins Or Medals?
This involves scanning a plaster maquette to produce a 3D digital representation of gold medals or coins. The equipment used is specially designed to record the specifics and dimensions of the model in digital format. The digital replica serves a variety of purposes during the production process.
3D Scanning Technique- High resolution 3D scanners are used to capture dimensions and details on models made of plaster. They record measurements and geometrical information using different methods like laser scanning or the structure light.
Capturing surface information- The scan emits light beams or lasers on the model. The scanner records the reflections and distortions. The information gathered is used to build models.
Data Collection. When the scanner is moving over the model, it collects many data points. The result is a digital representation of the model's shape contours, details, or contours.
Conversion into 3D Model. Specialized software reconstructs information from the collected data into a 3D model. The model is a representation of the physical and dimension of the maquette made of plaster.
There are many reasons to create an 3D digital model
Digital 3D models can be used to recreate the exact details and dimensions of a physical model. This accuracy ensures that the final gold medals and coins will match the design.
Facilitating Modifications- Digital models can be easily modified or refined. Designers are able to modify the design without altering the maquette made of plaster.
Compatible with Manufacturing ProcessesCompatibility with Manufacturing Processes Digital 3D models are compatible with different manufacturing processes including CNC machining or 3D printing and enables the creation of molds or dies for mass production.
Digital 3D models can be utilized to preserve and document the design. You can save them digitally to be a reference in the future, for reproductions, or for preserving the history of the design.
Manufacturers and designers can use modern manufacturing techniques to make gold coins and medals which are exact and faithful to the original design by scanning models of plaster and generating digital 3D models.

What Is The Process By Which A Janvier Machine Transfer A Gold Coin Or Medal Design From The Master Hub To A Functioning Hub?
The Janvier Machine, also called pantograph machine, or reduction device, is a machine that is used during the coining process to transfer concepts from a Master Hub the Working Hub. Here's a quick review of the Master Hub Creation.
The master hub is the original die, or mold, that has exactly the design of the medal or coin. It is made using precision CNC cutting.
Janvier Machine - Installation and Setup
The Janvier Machine is comprised of two elements: a stylus to trace the design, and a tool which cuts the design.
The Janvier machine has a master hub mounted securely. This is used as a basis upon where the design is transferred.
Tracing Design
The Janvier stylus follows the design's contours and the design details of the hub. When the stylus is moved on the hub's surface, it tracks its contours.
Reducing the Design
The Janvier machine also duplicates the pattern traced onto the working hub. This hub is typically composed of softer materials, such as steel or nickel, than the hub that is used as the master hub.
The cutting tool reduces, or duplicates the design to the hub that is working in a smaller or reduced dimension compared to the hub that is master. This is crucial to the process of minting as it allows for the making of coins or medals at the exact size.
Accuracy and Precision
Janvier is a precision machine that assures a perfect transfer of designs from the master hub onto the hub that is in use. The machine can reproduce even the tiniest details and contours.
Quality Control
The resulting working hub will be subjected to quality checks and examination to make sure that the design is in line with the specifications and accuracy needed for the striking process.
More Processing
The working hub created by the Janvier machine can be used as a tool during the striking of medals or coins process. The mold or die is used to create multiple coin blanks or medal blanks based on the design that was transferred.
The Janvier machine's function is vital for the minting process it allows the replication and reduction of intricate coin or medal designs from a master hub to working hubs accurately. These hubs are used to produce large quantities of medals and coins with the strike method.

What Are The Different Ways In Which Gold Coins Or Medals Are Coated To Guard Them?
Gold coins or medals can undergo coating processes for various reasons, including protection, improvement of appearance or to create particular aesthetic results. Here are some examples of different coatings that could be applied.
Clear Protective Film (Varies). This clear protective film, that can include lacquer as well as polymer, shields the surface of the coin from oxidation. The coating preserves the coin's or medal's original appearance and protects the underlying metal.
Enhancement Appearance
Gold plating, also known as gildingthe surface of a gold-plated coin or medal can be gilded or coated with a thin layer gold. This procedure enhances the look of a coin or a medal, bringing lustre and luxury to it.
Aesthetic effects
Antique or Patina Finishes - Chemical treatments or specialized coatings are used to create the appearance of an antique or patina finish. This process creates an aged or oxidized appearance to the surface. It gives the character and depth of your design.
Colorization or Coloring - Some metals or coins are colored in particular areas by using coatings, enamels, or specialized coatings. These colors can be used to highlight specific design elements or to make a contrast.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions and Coatings - to medals or coins with intricate designs or areas susceptible of tarnishing anti-tarnish coatings and solutions can be applied. These coatings will keep metallic surfaces from becoming discolored or oxidized with time.
