How Can A Janvier Transfer The Gold Design Of A Gold Coin Or Medal From The Master Hub Onto A Working Hub?
The Janvier machine (also known as pantographs or reducers) is a unique device that transfers a coin design or medal from the master hub onto the working hub. Here is an overview on how the Master Hub Creation works.
Master dies are the initial mould or die that has the exact design of the coin. It's usually produced through CNC machine or other precise methods to guarantee 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 master hub is mounted on the Janvier machine, and serves as the template from where the design can be transferred.
The Design-
The Janvier stylus in the machine captures the shape of the design when it moves across the surface of the master hub. The stylus captures the contour of the design when it travels across the hub's surface.
The reduction of design-related
In parallel, the cutting tool of the Janvier machine reproduces the pattern traced on the working hub which is composed of softer materials than the master hub, such as nickel or steel.
The cutting device reduces or transfers the design onto the hub of the working wheel in a smaller scale or size in comparison to the hub that is the master hub. This reduction is crucial for the process of minting, since it allows the making of medals or coins in the exact size.
Accuracy and Precision
The Janvier machine is operated with precision to ensure an exact transfer of the layout from the master hub to the working hub. It reproduces with precision all the details and curves, including the smallest details.
Quality Control
The quality of the final hub is assessed to ensure that the design of the transfer is in line with the requirements for striking processes.
Further Processing
The Janvier working hub is an tool for the striking process of coins or medals. It serves as a die or mold for a variety of medals or coins blanks with the transferred design.
The Janvier machine's purpose is essential in the process of minting it allows the reproduction and reduction of intricate coin or medal designs from master hubs to working hubs accurately. These hubs will be used to produce mass quantities of coins or other medals by using the striking process.

How And Why Are Some Types Of Finishes, Textures Or Textured Surfaces Achieved Through Sandblasting?
Sandblasting is a process employed to produce certain textures or finishes that include smooth or textured surfaces on gold medals or coins. This is the reason and how it is used.
Surface preparation the coin is placed in a cabinet or a chamber equipped with an air compressor and the nozzle. The abrasive material is usually located within this chamber.
Abrasive Material Selection - Fine particles of abrasive materials like sand, silicon carbide, glass beads or aluminum oxide, are thrust on the surface of the coin or medal at high speed.
High-Pressure-The abrasive grains are propelled towards the surface by compressed air or another high-pressure device. The force and speed that the particles encounter the surface create the desired finish or texture.
Texture Creation - The impact of the abrasive particles the surface creates a textured or matte appearance, by changing the topography of the surface. This process allows you to roughen certain areas or create a texture that's similar across the entire surface.
Controlled Application - The intensity length, duration, angle and the application of sand can be controlled to create various textures or surfaces. Different abrasives can be used to produce different results.
Sandblasting is used for various reasons
Texture Variation - Sandblasting can create an array of textures, including smooth, frosted and matte surfaces. These add visual attraction and distinctive qualities to medals and coins.
Aesthetic Improvement- Sandblasting changes the appearance of a surface. It diffuses light reflections and reduces the shine. This improves the appearance of a coin or medal. Matte finishes are a fantastic way to highlight the design elements.
Anti-Glare: A matte or textured finish created by sandblasting reduces reflections or glare. This helps the medals and coins appear more appealing, and they are easier to read without any unwanted light interference.
Sandblasting Creates Contrasting Design Elements Sandblasting can create a contrast between polished and texture areas on the medal or coin, emphasizing specific design elements or giving visual depth.
Sandblasting can be customized and creative. offers customization options, allowing for creative expression as well as the creation of medals and coins with distinctive texture or finish that is tailored to specific design requirements.
