How Does A Janvier Transfer The Gold-Colored Design Of A Gold Coin Or Medal From The Master Hub To Working Hubs?
The Janvier machine, sometimes known as a pantograph or reducing device is a special device that is used during the process of minting to transfer an image of a medal or coin from a master hub to the hub that is working. Here's an overview of how it works. Master Hub Creation-
Master dies are the initial mold or die that contains the exact design of the coin. It is usually made using CNC machine or other precise techniques to ensure accuracy.
Janvier Machine Setup
The Janvier Machine consists of two elements which include a stylus that trace the design and a tool that cuts the design.
The hub master is securely fixed to the Janvier machine, serving as the template from which the design will be transferred.
The design is traced
The Janvier stylus of the machine records the shape of the design when it moves along the hub's surface. As the stylus moves over the surface, it records the design profile.
Reduce the Design
The Janvier machine can also reproduce the pattern that was traced onto the hub that is in use. This hub is typically made from a softer material like nickel or steel, as opposed to the hub that is used as the master hub.
The cutting tool reduces or duplicates the design on the working hub with a smaller or less dimension compared to the hub that is master. This reduces the size of the process of coining since it permits medals or coins to be struck in the sizes desired.
Accuracy and precision
Janvier's machine is precise and guarantees a flawless transfer of design information from the master to the working hub. It is able to reproduce even the most minute details and contours.
Quality Control
The quality of the final hub is inspected to make sure that the design of the transfer is in line with the requirements for striking process.
More Processing
The hub of the Janvier's is a useful tool for striking coins and medals. The die or mold is used to create multiple medal or coin blanks based on the design that was transferred.
Janvier's machine is essential for coining. It permits the accurate replication and reduction from an original master hub to working hubs of intricate designs. These hubs are utilized to create large amounts of medals and coins through the strike method.

Why Are Gold Medals And Coins Cleaned By Hand?
Hand-polishing dies with care is vital to the creation of gold coins and medals to ensure a smooth and flawless surface. This is due to a number of reasons. Detail Reproduction- Hand polishing removes imperfections, burrs, or any irregularities that may occur on the die's surface. A smooth surface permits the details of the design to reproduce with greater precision on the coins and medals.
The polished die ensures that the medals or coins struck have sharp edges, clear details, and a good relief. This improves the quality and aesthetic appeal of the finished product.
Reduction of Wear and Tear - Polishing can reduce friction during the strike process. A smooth die's surface minimizes the likelihood of defects or inconsistencies with the struck coins or medals due to rough surfaces on the die.
Consistency when striking. Hand-polished dummies give a uniform strike surface, and ensure uniformity in the process of coining. Consistency ensures the accuracy and quality of the design on all coins or medals.
The longevity of Dies- Well-polished dies are less likely to be damaged or wear through the process of striking. They are longer-lasting and more durable, allowing for greater strikes without compromising product quality.
Accuracy and Precision- Hand polishing enables engravers to fine tune and refine specific areas of the die to ensure that the exact details are reproduced on the struck coins or medals. This level of precision adds to the accuracy of the final product.
Quality Control - Polishing is part of the quality control process. By hand polishing the die, you to identify and correct any inconsistencies or imperfections prior to the process of striking.
Surface Finish- Polishing can impart particular surface finishes or textures that enhance the appearance or adding unique characteristics to the struck metals or coins.
Hand-polishing the dies for gold medals and coins is essential to ensure that the products created are of high quality, beautifully intricate, and have a high aesthetic value. It is important to ensure the appearance, consistency and long-lasting quality of the final product.

How Does Gold Get Through The Coin Presses, And Then Stamped With High-Pressure During Minting?
During the process of minting, gold blanks must be loaded into coin presses and stamping at high pressure in order to create finished awards or coins. Here's the overview of procedures involved in loading blanks.
In a feeder system that is linked to the press, the gold blanks have already been prepared and quality checked. This feeder system guarantees that there is a constant supply of blanks to the press.
Feeding Blanks to the Press
The feeder system guides each blank into the zone of the coin presses. This guarantees the exact placement of each blank for stamping.
Alignment of Position
The blanks are aligned in the press and then placed into the striking room to ensure they are in the right place and aligned to allow for the stamping.
Striking Under Pressure
Coin presses gold blanks at high pressure using two dies: one stationary and the other moving. The stationary die contains the impression of the design that is negative while the moveable die is the Hammer.
The die that moves transfer the design from the blank onto its surface using a lot of force. Die pressure causes relief raised and details on the coin.
Striking repeatedly is optional.
Multiple strikes can be used to create a more sharply defined design or image on higher quality coins and medals. Each strike improves the surface details of the blank.
Ejection and Collection-
When they have been struck by hand, the medals and coins are ejected into trays. Quality control is performed to ensure the designs adhere to the specifications.
Post-Processing-
The design of the coin or medal might require additional processing such as edge lettering (either edge reeding) or post-strike treatments.
The process of stamping under extreme pressure is vital as it transfers the desired design to the gold blanks and transforms them into finished coins or medals ready to be used in circulation, collection or commemoration. This process is highly precise, since any alteration in pressure or alignment will affect the quality of the final product.
