How Does A Janvier Machine Transfer The Gold Medal Or Gold Coin From The Master Hub Onto A Working Hub?
A Janvier Machine, sometimes called a pantograph machine or a reducing device is a tool that is used during the coining process to transfer concepts from a Master Hub to the Working Hub. This is a brief overview of the Master Hub Creation.
The master hub, sometimes referred to as the original die or mold it is the mold or die that has the exact design and layout of the coin. It's usually produced through CNC machine or other precise methods to ensure precision.
Setup for Janvier Machine-
The Janvier machine has a stylus for tracing the design on the hub master, and a cutter that duplicates the pattern.
The Janvier machine's master hub, that serves as a template to which the design will be copied, is mounted in a secure manner to the machine.
Tracing Design
The stylus of the Janvier machine is able to follow the contours and specifics of the design of the hub master. As the stylus moves across the surface of the master hub it records the design's profile.
The reduction of design-related
On the Janvier cutting tool, it copies the designs traced onto the hub of the machine which is normally made out of steel, a soft metal or nickel.
The cutting tool cuts, or duplicates the design on the hub of work in a smaller or reduced scale as compared with the master hub. This reduces the possibility of striking coins and medals of the exact size.
Accuracy and Precision
Janvier is a precision machine that guarantees a precise transfer of designs from the master hub to the hub that is in use. The machine is able to reproduce even the tiniest details and curves.
Quality Control
The design and quality of the hub is inspected to make sure that the design of the transfer meets the requirements for striking processes.
More Processing
The hub of the Janvier's can be used as an tool for striking coins and medals. It can be used to make multiple blanks of the coin or medal with the design transferred.
Janvier is a key element in minting because it has the ability to accurately reproduce and reduce intricate designs on medals and coins. These hubs work to produce large quantities of coins or medals through the process of striking.

What Makes It Possible To Achieve Certain Textures Or Finishes Like Matte Or Textured Surfaces?
Sandblasting is a process used to achieve specific finishes or textures like smooth or textured surfaces on gold-plated coins or medals. The procedure of Sandblasting is explained.
Surface Preparation - The coin or the medal is placed into a chamber, cabinet or nozzle attached to an air compressor. The chamber can be enclosed to hold the abrasive product that is used during the process.
Abrasive Material Select- Abrasive particles such as glass beads, aluminum oxide silica carbide, and sand are propelled at high speed on the surface.
High-Pressure Propulsion - The abrasive particles are driven onto the surface using compressed air or another high-pressure device. The surface texture is created by the force and speed of the particles.
Texture Creation. The impact of an abrasive surface alters its topography to produce a rough, matte finish. This process is used to siftly roughen certain areas or create an even texture over the entire surface.
Sandblasting that is controlled- Sandblasting can be controlled in terms of intensity, duration, and angle of application to produce different textures or finish. Different pressure levels, abrasives and abrasives result in different outcomes.
Sandblasting is a necessity?
Texture Variation - Sandblasting creates an array of textures, which include the grainy, matte and frosted surfaces. They add visual fascination and unique qualities to medals and coins.
Aesthetic Improvement- Sandblasting changes the appearance of a surface. It diffuses light reflections and reduces the shine. This enhances the appearance of a coin or medal. Matte surfaces, such as those that reduce glare, may highlight particular design features.
Anti-glare Properties - The matte or textured finishes that are created by sandblasting decrease reflectivity and glare, which makes metals and coins more pleasant to see and more appealing.
Contrasting Elements in Design - Sandblasting can be used to create contrasts between areas which are polished or textured on a coin or medal. It can be used to emphasize certain features of the design and/or increase the depth and dimension.
Sandblasting is customizable to produce unique designs or textures.
