What Happens When The Janvier Machine Transfer Gold Coins Or Medals From A Master Hub To The Working Hub?
A Janvier is also known by the name pantograph or reduction machine, is used to transfer a design for a coin or medal from a master hub onto an operational hub. This is a brief overview of the Master Hub Creation.
The master hub is the primary coin die, or medal mold. To ensure its accuracy, it's typically produced using CNC machining and other precision methods.
Janvier Machine Setup
The Janvier machine is comprised of a stylus that traces the design on the master hub, and cutting tools that copy this design onto the working hub.
The Janvier machine is equipped with a master hub, which serves as a template for the transfer of the design.
Finding the design
The Janvier machine is equipped with a stylus that follows the contours, details and shape of the master wheel. When the stylus is moved on the surface of master hub it tracks its contours.
The reduction of design-related
In tandem with the Janvier, the cutting tool copies the designs traced onto the machine's hub that is typically constructed from an abrasive material such as steel or Nickel.
The cutting tool replicates or cuts down the design on the working hub to the size or scale in comparison to the hub that is master. This reduction allows for striking coins and medals in the desired size.
Precision and Accuracy
Janvier is a precise machine that assures a perfect transfer of design from the master hub to the hub that is in use. It is able to reproduce even the tiniest details and contours.
Quality Control
The quality of the final hub is assessed to ensure that the design of the transfer meets the specifications required for the striking processes.
Further Processing
The Janvier machine's hub of working is utilized to make coins or medals. It is used as a mold or die that is used to make multiple blanks for medals or coins that have the design transferred.
Janvier is a key element in minting because it is able to precisely replicate and reduce complex designs for coins or medals. These working centers are then used to produce large quantities of medals and coins by through the strike method.

How And Why Is It Possible To Create Certain Textures Or Finishes Such As Textures Or Matte Surfaces?
This method can be used to achieving specific textures or finishes, such as matte and textured surfaces on the surface of medals or coins. The procedure of Sandblasting is explained.
Surface preparation- The metal or coin is placed in an enclosure or chamber with a nozzle that is connected to an air compressor. The chamber is typically enclosed in order to keep the abrasive used during the process in a sealed.
Abrasive material selection - High speed propulsion of fine particles of abrasive materials, such sand or silicon carbide or glass beads and aluminum oxide on the surface.
High-Pressure Propeller- The abrasive particle is propelled onto the surfaces using compressed air. The texture and finish of the surface are dependent on the force and velocity with which the particles impact the surface.
Texture creation: By altering the surface's topography because of the impact of the abrasive particle it creates a texture. This is used to create a smooth surface, or to create rough texture in specific regions.
Sandblasting that is controlled- Sandblasting can be controlled in terms of intensity as well as duration and angle of application to achieve varying textures or finish. Different abrasives, pressure levels and abrasives can produce different results.
Sandblasting is a necessity?
Texture Variation- Sandblasting permits for the creation of diverse types of textures and finishes such as matte, frosted, or grainy surfaces, which adds the appearance of interest and distinct characteristics to the coins or medals.
Aesthetic Enhancement- Sandblasting alters the appearance of a surface. It disperses light reflections and decreases the shine. This enhances the visual appeal of a medal or coin. Surfaces that are matte, like ones that cut down on glare can highlight specific design details.
Anti-Glare properties- Matte or the textured surfaces that are created through sandblasting can help reduce reflections and glare, making the coins or medals more visually appealing and easier to view without interference from light.
Contrasting design elementsSandblasting can produce contrast between the polished and textured parts of a medal or coin. This can help to highlight specific features, or add visual depth.
Sandblasting can be customized, which includes artistic expression, as well as creating unique coins or medals that feature textures or finishes customized to meet specific specifications for design.
Sandblasting, a method that is versatile, is used to create various designs and finishes for the surface of medals or coins. It improves their visual appeal, aesthetics, and overall design.

How Do You Put Gold Blanks Into Coin Presses?
When minting is completed gold blanks are loaded into coin presses, where they are stamped under high pressure to transform them into coins or medals. This is a brief overview of the process of loading blanks.
Gold blanks, which have been previously examined and prepared for quality they are loaded into a feeder system connected to the coin press. This feeder system guarantees an ongoing flow of blanks.
Feeding Blanks to the Press
The feeding system is designed to guide the blanks one-by-one into the chamber for striking. This ensures precise placement of the blanks.
Alignment & Positioning
The blanks in the pressing chamber are positioned, aligned and perfectly oriented to ensure that they are stamped.
Striving Under Pressure
The coin press puts high pressure onto the gold blanks using two dies, one stationary and one moving. The stationary die makes a negative impression on the shape of the coin, whereas the moving one is the hammer that strikes the blank.
The dies strike the blank with a lot of force, transferring the design onto its surface. The dies pressurize the design, resulting in raised relief on the medal or coin.
Striking repeatedly
In order to create designs or images that are sharper and more clear, several strikes may be applied on high-quality coins or collectible editions. Each strike further refines the details on the surface of the blank.
Collection and Ejection
Following the press's operation, newly-minted coins or medals are thrown out of the press into containers or trays. They are checked for quality control to ensure that designs stamped meet all standards and criteria.
Post-Processing-
If the mint requires it, they may also apply other processes, such as edge lettering, reeding of the edges, or post-strike treatments.
The process of stamping under high pressure is crucial in that it imparts the desired design onto the gold blanks, transforming them into medals or coins that are ready to be used in circulation, collection or for commemoration. This process is highly precise, as any change in alignment or pressure will affect the overall quality of the coin.
