The Maquette is sculpted using the gold pattern as a template. The process involves shaping the plaster in order to create a relief or a three-dimensional model of the coin or medal.
Refinement and Detailing The artist will concentrate on adding fine details, redefining the shape of the design and ensuring that the proportions are correct. Attention to detail and precision are essential at this point.
The time needed for drying and setting After the sculpting has been done, the sculpted plaster must be allowed to dry and settle. This allows for the maquette's form to be retained and its hardening.
Finishing and Smoothing Finishing and Smoothing - The maquette's surfaces are further refined and polished after drying to remove imperfections rough spots, bumps, and imperfections.
Sealing and Preservation - To preserve maquettes and make them ready for the future process like scanning or mold making, an adhesive or protective layer may be put on.

How Does The Janvier Machine Transfer Gold Medals Or Coins From Master Hubs To The Working Hub?
A Janvier machine is also known as a pantograph, or reducing machine. It's used to transfer the designs of a coin or medal from a master to the working center. This is a brief description of this Master Hub Creation.
Master dies are the original mould or die that has exactly the design that appears on the coin. It is usually made using CNC machine or other precise techniques to ensure accuracy.
Janvier Machine - Setup
The Janvier machine includes an instrument for drawing the design on the hub master, and a cutter that duplicates the design.
The hub master is securely fixed to the Janvier machine and acts as the template from where the design will be transferred.
Tracing Design-
The Janvier machine employs styluses to trace the contours and details of the design. The stylus captures the contour of the design as it moves across the hub's surface.
Reduce the Design-
In parallel, the Janvier machine's cutting tool replicates the traced design the hub that is working. The hub is constructed from a less hard metal than the master, usually steel or nickel.
The cutting tool reduces, or copies the design to the working hub in a smaller or reduced scale as compared with the hub that is master. This reduces the possibility of striking coins and medals that are the exact size.
Precision and Accuracy-
Janvier's machine is precise and ensures the perfect transfer of design information from the master to the work hub. The machine is able to reproduce even the most minute details and contours.
Quality Control
The resulting working hub is subject to quality checks and examination to make sure that the transfered design meets the specifications and precision required to strike it.
More Processing
The Janvier machine's working hub can be used to create coins or medals. The mold or die is used to make multiple medal or coin blanks using the transferred design.
The Janvier machine plays a crucial role in the minting procedure, as it allows the exact reproduction and reduction of intricate designs on medals and coins from a working hub to the master hub. These hubs then are utilized in the mass production of medals and coins by striking.

How Are Gold Blanks Supplied And Stamped With High Pressure Into Coin Presses For Minting?
During the production process Gold blanks will be taken into coin presses in which they are pressed using high pressure. This transforms them into completed coins or medals. Here is a quick overview of the steps in loading blanks.
In a feeder system linked to the press, the gold blanks have already been prepared and tested for quality. This feeder system is accountable for maintaining an uninterrupted flow of blanks into the machine.
Feeding Blanks into the Press
The feeding system is designed to direct the blanks one at a time into the striking chamber. This guarantees the exact placement of each blank to be stamped.
Alignment, Positioning and Positioning
The blanks are placed and positioned in the striking chamber of the press in order to ensure they are perfectly centered for the stamping process.
Moving under Pressure
A coin press applies pressure to the blanks of gold using two dies, one stationary, the other moving. The stationary die makes negative marks on the design of the coin, while it is moving that die acts as the hammer, which hits the blank.
The die moving transfer the design of the blank onto its surface with considerable force. Die pressure results in raised relief and detail on the coin.
Repeated Striking-
Multiple strikes can be utilized to create a more sharply defined design or image on better quality coin and medals. Each strike refines the detail in the blank.
Ejection and Collection-
The coins or medals will be released and placed into containers or trays when they've been struck. Quality control is carried out to ensure the designs adhere to specifications.
Post-Processing-
The style of the coin or medal could require further processing, for example, edge lettering (either edge or reeding) or post-strike treatments.
The process of stamping gold blanks using high pressure is essential as it imprints the desired design on them, making them finished medals and coins which can be used for the purpose of commemoration and collection, or even circulation. Precision is required, as any slight deviation in the pressure or alignment of the gold-plated blanks may result in a negative impact on the appearance and quality of the final product.
