Smoothing and Finishing- Following drying the maquette's surface is smoothed and refined to remove any imperfections, bumps, or rough areas.
Sealing and Preservation - To protect maquettes and prepare them for the future process like scanning or mold making, an adhesive or protective layer can be applied.
The final plaster maquette represents the gold coin or medal design in a three-dimensional form.

What Is The Process By Which An Janvier Machine Transfer The Design Of The Gold Coin To The Hub That Is In Operation?
A Janvier is also known under the terms pantograph and reducing machine, can be employed to transfer designs for a medal or coin from a master hub onto a working hub. The Master Hub Creation is explained in this video.
The master hub, also known as the original die or mould, is the first mold or die which contains the exact design and layout of the coin. To ensure accuracy the hub is usually made using CNC machineries and other high-precision methods.
Janvier Machine Setup
The Janvier machine includes a stylus, which copies the design of the master hub onto the working hub.
The Janvier machine is equipped with the master hub that is securely mounted. This is used as a template to where the design is transferred.
Tracing a Design
The Janvier machine's stylus records the contour of the design while it moves along the surface of the master hub. When the stylus is moved on the surface of the master hub it keeps track of its shape.
The reduction of design-related
The cutting tool on the Janvier machine replicates the traced design onto the working hub, which is usually composed of softer materials than the master hub, such as nickel or steel.
The cutting tool reduces or transfers the design onto the hub of the working wheel, but at a lower scale or size in comparison to the master hub. This is crucial for the process of coining since it allows medals and coins to be made at the desired sizes.
Precision and Accuracy
Janvier's machine operates with a high degree of precision, which ensures that the transfer is precise from the master hub onto the working hub. It replicates every single detail and contours precisely.
Quality Control
The resulting working hub is subject to quality checks and examination to make sure that the design is in line with the specifications and accuracy needed to strike it.
Further Processing-
The Janvier machine creates a working hub which is utilized in the medal and coin striking process. It serves as a mold, die or die to make multiple medals or coins blanks with the transferred design.
Janvier's machine is crucial for coining. It allows exact replication and reduction from an original master to working hubs of complex designs. Working Hubs are utilized for the production of large quantities of coins and medals by the strike process.
