The Janvier machine is fitted with a master hub which serves as a template for the transfer of design.
Tracing the design-
The Janvier stylus in the machine captures the contour of the design as it moves across the hub's surface. When the stylus is moved on the hub's surface, it tracks its contours.
The Design of the Home
The Janvier machine copies simultaneously the traced-out design onto the hub for work. It is typically made with softer components than the master wheel for example, steel or nickel.
The cutting tool reduces or duplicates the design onto the hub that is working at an enlarge or decreased size compared to the hub that is used as the master hub. This is essential for the minting process, as it allows for the striking of medals or coins at the exact size.
Precision and Accuracy
Janvier machines are operated precisely to ensure a precise transfer of designs from the master hub to the operating hub. The machine can reproduce even the most minute details and curves.
Quality Control
Quality checks and inspections are carried out to ensure that the design used is compatible with the requirements and accuracy needed to strike the design.
Further Processing
The Janvier working hub acts as an instrument to facilitate the striking process of medals or coins. It's used as a mold, or die to create multiple empty medals or coins with the transfered design.
The Janvier machine's purpose is essential in the minting process it allows the reproduction and reduction of intricate coin or medal designs from a master hub to working hubs accurately. These working hubs will then be used to create mass production of coins or other medals by using the strike process.

Why Are Gold-Plated Coins And Medals Polished By Hand?
It is for a variety of reasons that it is vital to polish dies with a hand in order to have a smooth, perfect surface. Enhanced Detail reproduction- When you polish the die by hand, any imperfections, burrs or any other irregularities are removed from the die's surface. The smooth surface allows for an improved reproduction of the exquisite details and intricate designs on the struck medals or coins.
A polished die improves the appearance of medals and coins. It improves the aesthetics and quality of your final product.
Reduced Tear and Wear Polishing is an excellent option to reduce friction and wear when striking. A smooth surface on the die minimizes the possibility of imperfections or irregularities on the struck coins or medals due to rough surfaces on the die.
Consistency of Striking Hand-polished dies ensure uniformity during the process of minting by ensuring a consistent striking area. Consistency ensures the quality and accuracy of the design on all coins and medals.
Durability of the DiesDies that are well-polished are less likely to be damaged or wear in the process of striking. Die dies are more durable and long-lasting and allow for more strikes to be struck without sacrificing quality.
Precision and Accuracy. Hand polishing allows engravers to precisely fine-tune, refine and even make sure that specific areas are perfect on the die. The details will be accurately replicated on the coin or medal. The precision of the final product is increased by this level of precision.
Quality Control – Polishing forms part of a quality control procedure. By inspecting the die before hand polishing permits the detection and correction of any imperfections or irregularities prior to the process of striking.
Surface Finish- Polishing can give specific textures or finishes to surfaces, enhancing the visual appeal or adding unique characteristics to the metals or coins.
Overall, meticulous hand polishing of the dies used for gold coins and medals is essential to making sure that you get high-quality accurate, precise, and visually appealing created products.

How Is Gold Fed Into The Coin Presses, And Then Stamped Under High-Pressure While Minting?
When the production process is completed gold blanks are placed in coin presses, which stamp them using high pressure. The result is completed coins or medals. Here's an overview of the steps involved Loading Blanks-
A feeder system is connected to the coin press. The system loads gold blanks that have been prepared and checked for quality. This feeder system ensures a continuous supply of blanks to the machine.
Blanks for Feeding to the Press
The feeder system directs each blank to the strike area of the coin presses. This ensures precise placement of the blanks.
Alignment, Positioning and Positioning
The blanks are positioned and aligned inside the striking chamber of the press to ensure that they are perfectly centered for the stamping operation.
Striking under High Pressure
Coin presses put massive pressure on gold blanks by using two dies -- one stationary and one mobile. The stationary die is equipped with negative designs that are made on the coin, and the moving die is used to strike the blank.
The moving die hits the blank with considerable force, and the design is transferred on the blank surface. The pressure of the dies creates the design as well as the raised relief.
The repetition of striking is not required.
To create designs or images that are clearer and more clear, several strikes can be applied to rare coins or collectible editions. Each strike refines the detail inside the blank.
Ejection and Collection
Following the press's operation, newly-minted coins or medals are released from the press onto trays or containers. Quality control is carried out to ensure that the designs conform to specifications.
Post-Processing-
The style of the coin or medal may require additional processing for example, edge lettering (either edge or reeding) or post-strike treatment.
Stamping the gold blanks with high pressure is vital because it prints the desired design on them, making them refined coins and medals which can be used for celebration or collection purposes, or for circulation. This process is highly precise, as any change in pressure or alignment will affect the quality of the final product.
