How Does A Janvier Transfer The Gold-Colored Design Of A Coin Or Medal From The Master Hub Onto Working Hubs?
A Janvier machine, also referred to as a pantograph, or reducing machine is a special device that is used during the process of minting that transfers the design of a medal or coin from a master hub to the hub that is working. Here's an overview of the process it uses to accomplish this Master Hub Creation-
The master hub is the primary coin or medal die or mold. It is usually made using CNC cutting or other high-precision methods to ensure precision.
Janvier Machine - Installation and Setup
The Janvier Machine consists of two components: a stylus to trace the design and a cutting tool that cuts the design.
The Janvier machine is equipped with an incredibly secure master hub. This is used as a basis upon where the design is transferred.
Tracing a Design
The Janvier machine features a stylus that is able to follow the contours, details and shape of the master wheel. The stylus records the profile of the design as it moves across the surface of the hub.
Reduce the Design
The Janvier machine copies simultaneously the drawn-out design onto the work hub. This is usually constructed with softer components than the master wheel such as nickel or steel.
The cutting tool replicates or reduces the design of the hub that is working to the size or scale compared to that of the hub that is master. This reduction is vital to the process of minting because it permits the sculpting of coins or medals at the size you want.
Accuracy and Precision
Janvier is a precise machine that assures a perfect transfer of design from the master hub onto the working hub. It recreates every single detail and contour with accuracy.
Quality Control
The design and quality of the hub is assessed to ensure that the design of the transfer is in line with the specifications needed for striking processes.
Further Processing
The working hub created by the Janvier machine can be used as a tool during the medal or coin striking process. It is used as a mold or die to create a variety of blank coins or medals with the transfered design.
The Janvier machine plays a crucial role in the minting procedure by allowing the exact replication and resizing of intricate designs on medals or coins from a working hub to the master hub. These hubs then are used for the mass production of coins or medals by striking.

How Is Gold Fed Through The Coin Presses And Then Stamped Under High-Pressure During Minting?
When the production process is completed gold blanks are fed into coin presses in which they are pressed with high pressure. This transforms them into completed coins or medals. This article provides a brief description of the steps in loading blanks.
Gold blanks that have been prepared and inspected for quality they are fed into a feeder system, which is connected to the coin press. The feeder system is responsible for maintaining that blanks are continuously flowed into the coin press.
Feeding Blanks Into the Press
The feeding system was designed to direct the blanks one at a time into the striking chamber. This ensures accurate positioning of each stamping blank.
Alignment and Positioning
The blanks inside the press chamber are aligned, positioned, and oriented perfectly to ensure that they are stamped.
Strumping in High Pressure
The coin press presses gold blanks using the highest pressure using two dies: one stationary, and the other moving. The stationary die is the negative impression of the design of the coin, and the one that moves is the hammer that strikes the blank.
The die moves and strikes the blanks using a lot of force. The design is transferred to the surface of the blank. The die's pressure creates the design as well as the raised relief.
Repeated Striking-
For higher-quality coins or medals, especially proof or collector's editions, a variety of strikes can be applied to achieve an even more sharp, clear visual or a design. Each strike helps to refine the details inside the blank.
Ejection and Collection
Once struck, the coins or medals that are produced are removed from the press. They are then put in trays and containers. Control of quality is conducted to ensure the designs adhere to specifications.
Post-Processing-
According to the design or mint specifications Coins and medals may be subjected to additional treatments like edge lettering or reeding as well as post-strike treatment.
Stamping under high pressure imparts the desired designs onto the gold blanks, changing the coins into medals that are suitable for circulation, collections or even commemoration. This process is extremely precise, because any deviation in pressure or alignment can impact the appearance and quality of the final product.
