What Is The Process By Which Janvier Transfer The Gold-Colored Design Of A Gold Coin Or Medal From The Master Hub To An Operational Hub?
The Janvier machine, also referred to as a pantograph or reducing machine is a special device used in the process of minting that transfers a coin or medal design from a master hub to a working hub. The Master Hub Creation is explained in this video.
The master die is the primary mould or die which contains the exact design on the coin. To ensure accuracy it is typically made with CNC manufacturing and other precise methods.
Janvier Machine Installation
The Janvier machine is made up of a stylus, which trace the design on the hub master and a cutting tool that replicates the design onto the working hub.
The Janvier machine includes a master wheel that is linked to the machine. It serves as a model, from which designs will be transferred.
The design is traced
The Janvier stylus in the machine captures the shape of the design as it moves along the surface of the master hub. As the stylus moves over the surface, it record the design's profile.
Reducing the Design
Simultaneously on the Janvier, the cutting tool reproduces the design traced on the machine's hub, which is usually made out of a soft material like steel or Nickel.
The cutting instruments reduce or replicate the design at the smaller scale or a reduced size, compared to master hub. This reduction in size is critical in the making of medals and coins which allows them to be struck at the right dimensions.
Precision and Accuracy
The Janvier machine operates precisely to ensure an precise transfer of the design from the master hub to the working hub. It reproduces every detail and contour with precision.
Quality Control
The final working hub goes through quality checks to ensure it is in compliance with the requirements to strike and is accurate.
Additional Processing
The hub of Janvier can be used as an tool for striking coins and medals. It acts as a mold or die for creating multiple blanks for medals or coins with the transfer design.
Janvier machines are crucial in the creation of coins and medals. They enable the precise reproduction of intricate coins or badge designs. The working hubs can be used to produce mass quantities of coins and other medals using the striking process.

Why And How Are Certain Finishes Or Textures Like Matte Or Textured Surfaces Achieved Through Sandblasting?
Sandblasting is a great method to create matte or textured surfaces on gold or silver coin and medals. The method of Sandblasting is described.
Surface preparation - The medal or the medal is placed inside a cabinet, chamber or nozzle that is connected to an air compressor. The chamber is usually sealed to keep the abrasive that is used to prepare the surface.
Abrasive Material Select- Abrasive particles like glass beads, aluminum oxide, silica carbide, and sand are launched at high speed to the surface.
High-Pressure Propulsion- The abrasive particles are propelled onto the surface with compressed air or another high-pressure system. The surface texture is produced by the speed and force of the particles.
Texture creation. The force of an abrasive on a surface alters the topography of the surface to create a textured, matte finish. This process can be used to create a uniform texture or roughen particular areas.
Controlled Application - The intensity, duration, angle, and application can be controlled to create various textures or surfaces. Different abrasives, pressure levels and abrasives result in different outcomes.
Sandblasting is a necessity?
Texture Variation: Sandblasting is a great method to create different texture or finish on coins and medals, such as polished or frosted surface. It adds visual appeal and distinct features.
Aesthetic Enhancement - Sandblasting changes the appearance of the surface by reducing the shine and diffusing light reflection. This can improve the aesthetic appeal of the medal or coin. Matte finishes are a great option to showcase the design elements.
Anti-Glare - A matte or textured finish produced by sandblasting reduces glare or reflections. This makes the medals or coins look more attractive, and also easier to read without any unwanted light interference.
Contrasting Elements in Design - Sandblasting can be used to create contrasts between areas that are polished or textured on a coin or a medal. It can be used to emphasize certain features of the design or to add dimension and 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 design requirements.
Sandblasting is an ingenuous technique that can be utilized on gold coins in order to create different surface textures. It also enhances the overall appearance of the medals.
