Installation for Janvier MachineSetup for Janvier Machine
The Janvier machine has stylus, which copy the design of the master hub to the one that is working.
The Janvier machine includes a master wheel that is connected to the machine. It functions as a model to which designs can be transferred.
The design is traced
The Janvier machine is equipped with a stylus that follows the contours, details and design of the master wheel. When the stylus is moved on the hub's surface, it records its profile.
The reduction of design-related
The Janvier machine also replicates the pattern that was traced onto the working hub. This hub is typically constructed from a soft material, such as nickel or steel, rather than the hub used in the master.
The cutting tool reduces, or duplicates the design on the hub that is working in a smaller or reduced dimension compared to the master hub. This is crucial in the process of minting, since it allows the striking of coins or medals at the desired size.
Accuracy and Precision
Janvier machines are controlled precisely to ensure the exact transfer of the design from master hub to working hub. It faithfully reproduces the tiny details and contours.
Quality Control
Quality checks and inspections are conducted to confirm that the design transferred matches the specifications and precision required for the process of striking.
Further Processing
The working hub created by the Janvier machine is used as a tool in the striking of medals or coins process. The die or mold is used to make multiple medal or coin blanks by using the transfer design.
Janvier machines are essential in the creation of coins and medals. They permit the exact reproduction of intricate coins or badge designs. The working hubs can be used to create mass production of coins and other medals using the strike process.

How Do Gold-Plated Coins And Medals Get Their Protective Coatings?
The coating process is utilized to safeguard, improve the appearance, or achieve certain aesthetic effects. Here are a few different coating methods.
Clear protective coating (Varies) A clear protective layer, such as a polymer or lacquer, is used to protect the coin or medal's surface from tarnishing or oxidation. The coating is designed to preserve the original look and appearance as well as safeguards the metal underneath.
Enhancement of Appearance
Gilding or gold plating- The surface of a gold coin medal could be covered with a fine layer of of gold. This can enhance the appearance of the medal or coin and gives it a more lustrous and luxurious look.
Aesthetic Effects
Antique or Patina finishes- Chemical treatments or special coatings are applied to produce the appearance of an antique or patina finish. This process artificially age the surface, creating an aged look that is oxidized.
Coloration or coloring- Specific areas of a medal could be colored with special enamels or coatings in order to emphasize design elements, create contrast or to add visual attraction.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions and Coatings - For medals and coins with intricate designs or areas susceptible of tarnishing anti-tarnish coats or solutions may be applied. These coatings are made to prevent the metal from oxidizing or discoloring over time.
Specialized Coatings for Security or For Authentication
UV-Reactive Coatings and Luminescent Coatings Some coins and medals have coatings that are UV reactive, which reveal the hidden elements or encryptions used to ensure security or authentication.
Selective Coatings to Block Contrast
Selective Coating RemovalIn some instances, the coatings of medals or coins are removed in a specific manner to provide contrast when polished and coated surfaces.
Each procedure has a particular purpose, for instance, to improve the appearance of the metal, protect metal, add security, or create certain aesthetic effects.

How Do Gold Blanks Get Being Fed And Stamped Using High Pressure In Coin Presses For Minting?
During the coining process, blanks of gold are loaded into coin presses at extreme pressure. They are then stamped to make completed coins or medals. Here's a quick overview of loading blanks.
In the feeder system connected to the press, gold blanks are prepared prior to the press and quality checked. This feeder system ensures a continuous supply of blanks to the machine.
Feeding Blanks Through the Press
The feeder system feeds the blanks into the striking chamber inside the coin press one at a time. This ensures precise positioning of each blank prior to stamping.
Alignment and Positioning
Inside the press, blanks are aligned and placed in the striking chamber making sure that they are perfectly centered and aligned to allow for the stamping process.
Striking Under Pressure
The coin press puts an intense pressure on gold blanks using a pair of dies--one stationary and one that moves. The stationary dent contains the negative design impression and the die that moves is the Hammer.
The die is moved and struck the blanks using a lot of force. The design is transferred to the surface of the blank. The force of the dies creates the design and the relief is raised.
Repeated Striking is Optional
Multi-strikes can be used to create more expensive coins or medals for example, like proofs or collectors' editions. The result is a sharper and more defined appearance. Each strike improves the finer details on the surface of the blank.
Collection and ejection
After being struck, newly-minted medals or coins are ejected from the press onto containers or trays. The designs that are stamped are examined to determine if they conform to the standards set by the manufacturer.
Post-Processing-
If the mint requires it, they may also apply additional procedures, such as edge lettering, reeding of the edge, or post-strike treatments.
High-pressure stamping that creates designs on the gold blanks is vital, as this converts them into finished coins or medals that are used for collection, circulation, or commemoration. This process is highly precise, since any alteration in pressure or alignment could impact the quality of the final piece.
