What Does A Plaster Mold Serve As The First Physical Representation For A Gold-Plated Coin, Medal, Or Any Other Item?
Creating a plaster mold or "maquette" based on the gold medal or coin design involves several steps to translate the two-dimensional model into a three-dimensional physical representation Initial Design Reference- The artist or designer uses the gold coin or medal design as a source of reference. This design can be a hand-drawn drawing or a design created using graphics design software. Other materials like wax and clay could be used.
Plaster preparation is combined with water to create an able consistency. It is crucial that the mixture is smooth with no lumps and uniform to create a mold.
Creating the Base- A base or platform is created where the maquette will be created. The base can be a wooden board or flat surface which provides stability.
The Maquette is sculpted using the gold pattern as a reference. It is the process of shaping the plaster in order to make a relief or three-dimensional version of the coin, or medal.
Detailing and Refinement The artist will be focusing on adding fine details, redefining the contours of the design, and making sure that the proportions are precise. Attention to detail and precision is required at this stage.
Allowing for Drying and Setting- Once the sculpting is completed, the plaster requires time to set and dry. This will allow the maquettes to set and maintain their shape.
After drying, the surface will be refined to remove bumps or imperfections, as well as rough areas.
Sealing and Preserving- To keep and preserve the maquette, and to prepare it for further processes, such as scanning and molding, you can apply a protective or sealant layer on its surface.
The three-dimensional plaster maquette that results is used to depict the gold design of a coin or medal. It serves as a reference to physical objects for the next steps of the production process like scanning to create digital replicas, creating molds to make mass production, or even as a reference for artists to visualize and refine the design prior to production.

How Does A Janvier Machine Transfer A Gold Medal Or Gold Coin From The Master Hub Onto A Functioning Hub?
A Janvier machine can also be referred to as pantograph, also known as a the reducing machine. It's employed to transfer the design of a coin or medal from the master to the working center. Here's an overview of how it accomplishes this Master Hub Creation-
The master die is the original mould or die which contains exactly the design that appears on the coin. It is made using the highest quality CNC cutting.
Janvier Machine Installation
The Janvier Machine consists of two elements which include a stylus that trace the design and a tool that cuts out the design.
The Janvier machine's master hub, that serves as a template to which the design will be re-created, is hung in a secure manner to the machine.
Tracing a Design
The Janvier machine employs stylus that follows the contours and fine details of the design. When the stylus travels across the surface, it captures the design profile.
The Design of the Home
In parallel, the cutting tool of the Janvier machine reproduces the design traced onto the working hub that is typically comprised of softer material than the master hub, like steel or nickel.
The cutting device cuts or copies the design onto the hub of the wheel at a reduced dimension or size compared to the hub that is the master hub. This reduction is vital to the process of minting because it permits the sculpting of medals or coins in the desired size.
Precision and Accuracy
Janvier machines are controlled with a high degree of precision to ensure the exact transfer of designs from master hub to working hub. It precisely reproduces every detail and contours, even the smallest of them.
Quality Control
The hub that is used for the operation will be subjected to inspection and quality control to ensure that it is in line with the specifications and is accurate for the strike process.
Further Processing
The Janvier machine's hub of working is used to create coins or medals. It's used as a mold or die to create a variety of medals or coins that are blank and have the design transferred.
Janvier machines are crucial to the production of medals and coins. They permit the exact reproduction of intricate coins or badge designs. These working Hubs are used for the production of large quantities of coins and medals by the striking procedure.
