How Does A Janvier Machine Transfer The Gold Coin Or Medal Design To The Working Hub From The Master?
A Janvier machine, sometimes referred to as a pantograph, or reducing machine, is a specialized machine used in the process of minting to transfer an image of a medal or coin from a master hub to a working hub. Here's a brief overview of how the Master Hub Creation works.
The master hub is the primary coin or medal die or mold. It is created using CNC machineries, or other techniques of precision.
Janvier Machine Setup
The Janvier machine includes stylus that copies the design from the master hub onto the one that is working.
The hub master is securely mounted on the Janvier machine, serving as the template from which the design will be transferred.
Tracing Design-
The Janvier stylus is a perfect match for the contours of the design and the details of the hub. As the stylus moves on the hub's surface, it keeps track of its shape.
Reduce the Design
The Janvier machine copies simultaneously the design that was traced out onto the hub for work. It is typically made from softer materials than the master wheel, like steel or nickel.
The cutting tools cut or reproduce the design on a smaller scale, or at a smaller size, compared to master hub. This is crucial for the process of coining because it allows coins or medals to be made at the sizes desired.
Accuracy and Precision
Janvier is a precise machine that ensures an accurate transfer of designs from the master hub to the hub that is in use. The machine is able to reproduce even the tiniest details and contours.
Quality Control
Quality checks and inspections are performed to verify that the design transferred matches the specifications and accuracy required to strike the design.
Further Processing
The hub of Janvier can be utilized as an instrument in the striking of coins and medals. The die or mold is used to make multiple medal or coin blanks by using the transfer design.
Janvier machines are crucial in the creation of medals and coins. They enable the precise replication of intricate coin or badge designs. The working hubs can then be used in the mass production process of medals or coins.

How Does Gold Get Into The Coin Presses And Then Stamped With High-Pressure While Minting?
In the process of production, gold blanks will be taken into coin presses which stamp them with high pressure. This transforms them into finished medals or coins. Here's a summary of the steps involved in loading blanks.
The gold-colored blanks are inserted into the feeder system, that is connected to coin presses. This feeder system will ensure that there is a constant supply of blanks for the press.
Feeding Blanks Into the Press
The system of feeding is designed to move the blanks one-by-one into the chamber for striking. This allows for precise positioning of the blanks.
Alignment and Positioning
The blanks inside the press chamber are placed, aligned and aligned perfectly to ensure that they are stamped.
Striking under High Pressure
The coin press has two dies: one stationary, and the other one is moving. The stationary die makes an impression of negatives on the design of the coin, while the moving one is the hammer, which hits the blank.
Die dies hit the blank with a great deal of force, which transfers the design onto its surface. The die's pressure creates the design as well as the relief is raised.
Repeated Striking
In order to create designs or images that are clearer and more clear, several strikes may be applied on rare coins or collectible editions. Each strike helps to refine the surface of the coin or medal.
Collection and Ejection
After being struck, the coins and medals are ejected into tray. The stamped designs are inspected for quality and ensure they conform to the standards set by the manufacturer.
Post-Processing-
Alongside edge letters and Reeding based on specifications for the design or mint specifications, certain coins or medals may undergo post-strike or other treatment.
Stamping with high pressure, which creates a design onto the gold blanks, is crucial and converts them into finished coins or medals to be used in circulation, collecting, or commemoration. It is essential to be precise, since any slight deviation in the pressure or the alignment of the gold-plated blanks may have a negative impact on the appearance and quality of the finished product.
