How Does A Janvier Machine Transfer A Gold Coin Or Medal Design From The Master Hub Onto A Functioning Hub?
The Janvier machine (also known as pantographs or reducing machines) is a specific device that allows the transfer of the design of a medal or coin from the master hub to the working hub. Here's a brief overview of how it accomplishes this Master Hub Creation-
The master hub is the primary coin or medal die or mold. It is made using high-quality CNC cutting.
Janvier Machine - Installation and Setup
The Janvier machine consists of a stylus, which trace the design onto the master hub, and a cutting tool that replicates the design onto the hub that is in use.
The Janvier machine is equipped with an incredibly secure master hub. It serves as the base from which the design is transferred.
A Design is traced
The stylus of the Janvier machine tracks the contours and fine details of the design that is on the master hub. The Janvier machine's stylus captures the shape of the surface as it moves across the surface.
Reduce the Design
Simultaneously the Janvier machine's cutting tool replicates the traced design to the hub in use. The hub is composed of a metal that is softer that the master usually steel or nickel.
The cutting device cuts or transfers the design onto the hub of the working wheel in a smaller dimension or size compared to the hub that is the master hub. This reduction allows for striking coins and medals that are the desired size.
Accuracy and Precision
The Janvier machine is operated with precision to ensure an accurate transfer of the design from the master hub to the work hub. The machine is able to reproduce even the smallest details and curves.
Quality Control
The final working hub undergoes quality tests to make sure it conforms to the specifications to strike and is exact.
Additional Processing
The Janvier machine produces a functioning hub for the coin and medal making process. It is able to make multiple blanks of the medal or coin with the designs transferred.
The Janvier machine plays an essential part in the production process because it permits the exact replication and resizing of intricate designs on medals or coins from a hub that is working to a master hub. These hubs work for the mass production of coins or medals through the striking procedure.

What Coating Techniques Are Employed To Shield Gold Coins And Medals?
Here are some of the different coating techniques that are used. Below are some of the different coatings that can be applied.
Clear Protective coating (Varies) - A clear protective layer, such a lacquer or polymer, is put on to protect the medal's or coin's surface from tarnishing or oxidation. The coating keeps the original appearance of the coin or medal, and protects its underlying metal.
Enhancement of Appearance
Gold Plating and Gilding Gold medals or coins may undergo gilding or gold plating processes in which the thin layer of gold is sprayed onto the surface. This gives the coin or medal the appearance of a luxurious, glossy appearance.
Aesthetic Effects
Antique or Patina finishes- Chemical treatments or coatings that are specialized are used to produce the appearance of an antique or patina finish. This method artificially ages the surface to create an aged, oxidized appearance.
Colorization or Coloring - In some cases, the color of specific areas of a coin, medal, or any other object is achieved by applying specific coatings and enamels. The goal is to enhance the design element, produce contrast, and increase the visual appeal.
Anti-Tarnish Coatings-
Anti-Tarnishing Solutions - These solutions or coatings can be used on medals and coins with intricate designs or have a tendency to tarnishing. The coatings stop metallic surfaces from becoming discolored or oxidizing over time.
Specialized Coatings for Security, or authentication-
UV-Reactive Coatings and Luminescent Coatings Some coins and medals are coated with coatings that contain UV reactive, which can reveal the hidden elements or encryptions used for security reasons or authentication.
Selective Coatings to Block Contrast
Selective Coating RemovableIn some instances, the coatings of medals or coins are removed selectively to create contrast when polished and coated surfaces.
Each coating has a reason for being there. It may be to protect the metal or improve its appearance. They can also be used to add security features.
