How Does A Janvier Machine Transfer The Gold Medal Or Gold Coin From The Master Hub To The Working Hub?
The Janvier machine (also known as pantographs or reducing machines) is a specific device that transfers the design of a medal or coin from the master hub to the operating hub. Here's a brief overview of how it works. Master Hub Creation-
The master hub is the original die, or mold, which contains the exact layout for the medal or coin. The master hub is typically made with CNC machines or other precision methods to ensure accuracy.
Janvier Machine Setup
The Janvier machine includes stylus, which copy the design from the master hub onto the working hub.
The Janvier machine's master hub, which acts as a template to which the design will be copied, is mounted with utmost security on the machine.
Tracing the Design-
The Janvier machine is equipped with stylus that is able to follow the contours, details and design of the master wheel. The Janvier machine's stylus captures the shape of the surface as it moves across the surface.
Reducing the Design
The Janvier machine also duplicates the pattern traced onto the hub that is in use. The hub is usually constructed from a soft material like nickel or steel, rather than the hub that is used as the master hub.
The cutting tool reproduces or cuts down the design of the working hub to a smaller size or scale compared to that of the hub that is master. This is essential for the process of minting, since it allows for the striking of medals or coins at the desired size.
Precision and Accuracy
Janvier is a precision machine that guarantees a precise transfer of designs from the master hub to the working hub. It reproduces every detail and contour with accuracy.
Quality Control
The quality of the resulting hub is inspected to make sure the transfer design meets the specifications required for the striking processes.
More Processing
The Janvier machine makes a functional hub for the coin and medal making process. It acts as a die or mold to make multiple medals or coins blanks with the transferred design.
Janvier's machine is crucial for coining. It allows accurate replication and reduction from the master hub to working hubs for complex designs. These hubs are used to produce large quantities of medals and coins using the striking method.

How Can You Achieve Smooth Or Matte Finishes Using The Process Of Sandblasting? And How?
Sandblasting is a process used to achieve specific finishes or textures like matte or textured surfaces, on gold coins or medals. The procedure of Sandblasting is explained.
Surface Preparation: The coin is placed inside a box or cabinet equipped with an air compressor and the nozzle. The chamber is typically covered to protect the abrasive material that is used in the process.
Abrasive Material Select- Abrasive particles like glass beads, aluminum oxide, silica carbide, sand and so on are launched at high speed onto the surface.
High-Pressure Propulsion- The abrasive particles are pushed onto the surface with compressed air or another high-pressure device. The force and speed at which the particles strike the surface produce the desired finish or texture.
Texture Creation. The force of an abrasive on a surface alters its topography creating a textured matte finish. This process is used to create a specific roughness in certain regions or create an even texture across the entire surface.
Sandblasting can have its intensity, duration and angle controlled to produce different finishes or textures. Different abrasives can produce different results.
Sandblasting is used for many reasons
Texture Variation- Sandblasting permits to create diverse textures or finishes, including matte, frosted, or grainy surfaces that add an aesthetic appeal and distinctive characteristics to the coins or medals.
Aesthetic enhancement- Sandblasting can change the appearance of the surface by diffusing light and reducing shine. This could enhance the appeal of the coin. Matte finishes may, for example highlight specific design features by reducing glare.
The anti-glare properties of using sandblasting, a matte or textured surface can be produced. This reduces glares and reflections. The medals and coins are attractive and clearer to view with no light interference.
The contrast of design elementsSandblasting may create contrast between polished and textured components of a medal or coin. This helps to emphasize particular features or to add visual depth.
Sandblasting permits customization that includes artistic expression and creating unique medals or coins with finishes or textures that are customized to meet certain specifications in design.
Sandblasting can create various textures and finishes on the surface of gold coins and medals. This enhances the overall appeal, appearance and appeal, in addition to aesthetics.

How Does Gold Get Through The Coin Presses And Then Stamped With High-Pressure While Minting?
When minting is completed gold blanks are loaded into coin presses and stamped under pressure to turn them into finished coins or medals. This is a brief overview of the how to load blanks.
A feeder system is attached to the coin press. The system is loaded with gold blanks that are prepared and tested for quality. This feeder system ensures that there is a constant supply of blanks for the machine.
Feeding Blanks in the Press
The feeder system introduces blanks into the strike chamber inside the coin press, one at a time. This ensures the exact placement of each blank before stamping.
Alignment and Positioning
The blanks are aligned within the press and then placed into the striking room, making sure they are centered and perfectly placed to enable the stamping.
Strumming at High Pressure
The coin press presses the gold blanks using high pressure using two dies: one stationary and another moving. The stationary die leaves negative marks on the design of the coin, while the moving one is the hammer that strikes the blank.
The die that moves transfer the design from the blank to its surface with a great deal of force. Die pressure results in relief raised and details on the coin.
Striking repeatedly
In order to create an image or design that is more sharp and clearer, multiple strikes can be applied to premium coins or editions of collectibles. Each strike refines the design of the surface of the blank.
Collection and Ejection
After being struck by the press, the coins or medals that are created are taken from the press. They then collect in trays and containers. Quality control is carried out to ensure the designs adhere to specifications.
Post-Processing-
The appearance of the coin or medal might require additional processing for example, edge lettering (either edge or reeding) or post-strike treatments.
High-pressure stamping which creates a design onto the gold blanks, is crucial, as this makes them into finished coins or medals for collection, circulation or for commemoration. This process requires precision as any variation in alignment or pressure could affect the quality and appearance of the final product.
