How Is A Plaster Mold Employed To Create A First Physical Representation Of A Coin Or Medal?
A gold coin or gold medal design can be used as a design reference by the designer or artist. The design may be a hand-drawn sketch or a digital model that is created with graphic design software.Choosing the appropriate medium- Plaster is an ideal material used to create maquettes due to its malleability and the ease of sculpting. Other materials, such as wax or clay can also be considered.
Preparation of Plaster - Plaster is mixed with water to make a workable consistency. It is crucial that the mixture is smooth, free of lumps and even to make a mold.
Base Creation- To create the maquette, a base or platform must be created. This base can be an unfinished wooden surface or an actual board.
The artist will start by sculpting a maquette using the gold-colored design. It is the process of shaping the plaster in order to make a relief or three-dimensional version of the coin, or medal.
Detailing Precision, Refinement, and Accuracy The artist's primary focus is making the details more clear and refining contours. They also ensure accuracy with respect to proportions. This process requires accuracy and focus.
Giving time to set and dry- Once the sculpting process is completed, the plaster must be allowed to dry and set. This allows for the maquette's shape to be retained and its hardening.
Finishing and Smoothing The maquette's surface gets further polished and refined after drying to eliminate imperfections, bumps and rough areas.
Preservation and Sealing- To preserve the maquette and prepare it for other processes such as scanning or molding the maquette, a sealant or protective layer might be applied to the surface.
The resulting plaster maquette serves as a tangible, three-dimensional depiction of the gold medal or coin design. It is an actual reference point for the next stage of production. For instance, it is possible to use it to scan for digital replication or to create molds for mass production. Also, artists may utilize it as a reference to help them visualize and improve their designs prior to the finalization of their design.

What Does An Janvier Machine Transfer The Design Of The Gold Coin To The Hub That Is In Operation?
A Janvier, also known by the names pantograph and reducing machine, can be used to transfer a design for a medal or coin from a master hub onto an operational hub. This is a brief overview of this Master Hub Creation.
The master hub is the primary die or mold that carries the exact design of the coin or medal. The master hub is generally made using CNC machines or other precision methods to ensure accuracy.
Janvier Machine Setup
The Janvier Machine is comprised of two components: a stylus to trace the design and a tool which cuts the design.
The Janvier machine includes the master wheel which is attached to the machine. It is used as a model from which designs will be transferred.
The Design-
The Janvier machine has a stylus that is designed to follow the contours, features and the design of the master wheel. The stylus on the Janvier machine records the profile when it moves on the surface.
Reduce the Design
The Janvier machine also replicates the traced pattern onto the hub that is in use. This hub is typically constructed from a soft material, such as nickel or steel, as opposed to the hub that is used as the master hub.
The cutting tool cuts, or duplicates the design to the working hub at a reduced or smaller size compared to the master hub. This reduction is crucial for the minting process, as it allows for the striking of medals or coins in the size you want.
Accuracy and Precision
Janvier's machine is operated with a high degree of precision, which ensures an exact transfer of data from the master hub onto the hub that is used for work. It replicates even the tiniest details and contours precisely.
Quality Control
The final working hub undergoes quality checks to ensure that it conforms to the specifications for striking and is precise.
Additional Processing
The Janvier machine creates a working hub that is used in the coin and medal making process. It is used as a mold or die that is used to make numerous blanks for coins or medals with the transfer design.
Janvier's machine is crucial for coining. It allows for the exact replication and reduction from a master to working hubs for complex designs. Working Hubs are utilized to produce large quantities of coins or medals through the process of striking.
