What Is The Process By Which The Janvier Machine Transfer Gold Coins Or Medals Design To The Working Hub Of The Master?
The Janvier machine (also known as pantographs, or reduction machines) is a unique device that transfers a coin design or medal from the master hub onto the working hub. This is a brief review of the Master Hub Creation.
The master hub is the original coin or medal die or mold. The majority of them are made by CNC machine or other precise techniques to ensure accuracy.
Janvier Machine Installation and Setup
The Janvier machine has an instrument for drawing the design onto the hub master as well as a cutter that duplicates the layout.
The master hub is mounted on the Janvier machine and acts as the template from where the design will be transferred.
Tracing the design-
The stylus on the Janvier machine follows the contours and details of the design that is on the hub master. The stylus captures the contour of the design as it moves across the hub's surface.
Reduce the Design-
On 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 tools reduce or duplicate the design at an enlarge scale, or at a smaller size, when compared to the master hub. The smaller size is crucial for the production of medals and coins making them possible to strike with the desired dimensions.
Accuracy and precision
Janvier is a precise machine that assures a perfect transfer of design from the master hub onto the working hub. It accurately reproduces all details and curves, including the smallest ones.
Quality Control
The hub that is created is subject to quality checks and examination to make sure that the design is in line with the specifications and precision required for the process of striking.
Further Processing
The Janvier working hub functions as an tool for the striking process of coins or medals. It serves as a mold or die to make multiple medals or coins that are blank and have the transferred design.
Janvier is a crucial component in the process of minting because it is able to precisely replicate and reduce complex designs for coins or medals. The working hubs can be used to produce mass quantities of coins and other medals using the striking process.

How And Why Are Certain Surfaces, Such As The Matte Or Textured Surfaces, Made By Sandblasting?
This technique can be used to make matte or textured surfaces on gold coins or medals. This method is used to achieve a number of different reasons.
Surface preparation- The metal or coin is placed inside the form of a cabinet or chamber with a nozzle that is connected to an air compressor. The chamber is usually sealed in order to keep the abrasive that is used during the process in a sealed.
Abrasive Material Select- Abrasive particles such as glass beads, aluminum oxide, silica carbide, and sand are launched at high speed onto the surface.
High-Pressure propulsion - Abrasive particles are delivered to the surface of the surface by with compressed gas or a different high pressure system. The force and speed at which the particles hit the surface produce the desired finish or texture.
Texture creation. The impact of an abrasive on a surface alters its topography creating a textured matte finish. This method can be used to create a uniform texture or roughen particular areas.
Controlled Application- Sandblasting may be controlled for intensity the duration, angle, and intensity of application in order to create different textures or the appearance. Different abrasives may produce distinct results.
Sandblasting can be used for many reasons.
Texture Variation: Sandblasting can allow for the creation of various types of textures and finishes such as matte, frosted, or even grainy surfaces that add the appearance of interest and distinct characteristics to the coins or medals.
Aesthetic Enhancement- Sandblasting alters the appearance of the surface by diffusing light reflections and decreasing shine, which may enhance the appearance of the coin or medal's appeal. Matte finishes are an excellent method to emphasize design elements.
Anti-Glare properties - By sandblasting, the appearance of a matte or textured surface could be created. This reduces glares and reflections. The coins and medals look more appealing and easier to see without light interference.
Sandblasting creates contrast in design Elements - Sandblasting creates a contrast between the texture and polished areas of the medal or coin, which emphasizes particular design elements or adding visual depth.
Sandblasting is a great way to create unique designs. It lets you express yourself artistically and produce coins and medals in a variety of styles and textures.
Sandblasting is a technique used to produce different surface textures or designs on gold coins or medals. This process enhances the aesthetics and visual appeal of these objects.
