What Is The Process By Which A Janvier Machine Transfer A Gold Medal Or Gold Coin From The Master Hub To A Functioning Hub?
The Janvier machine (also called pantographs or reduction machines) is a specific device that allows the transfer of the design of a medal or coin from the master hub onto the working hub. Here's a brief overview of the process it uses to accomplish this Master Hub Creation-
The master hub, also known as the original die or mold, is the original mold or die which contains the exact layout and design of the coin. It is made using CNC machineries, or other methods of precision.
Janvier Machine Setup
The Janvier Machine is comprised of two parts that include a stylus for drawing the design, and a tool which cuts the design.
The Janvier machine is equipped with an incredibly secure master hub. This is used as a base from where the design is transferred.
The Design-
The Janvier stylus is a perfect match for the design's contours as well as the details on the master hub. As the stylus moves across the hub's surface, it tracks its contours.
Reduce the Design
In parallel, the cutting tool of the Janvier machine copies the pattern traced on the working hub which is composed of softer materials than the master hub, such as nickel or steel.
The cutting device cuts or replicates the design on the hub of the working wheel, but at a lower scale or size in comparison to the hub that is the master hub. This reduction in size is essential to the production of medals and coins making them possible to strike with the desired dimensions.
Precision and Accuracy
The Janvier machine works with precision to ensure an exact transfer of the layout from the master hub to the operating hub. It faithfully recreates the tiny details and contours.
Quality Control
The final working hub undergoes quality tests to make sure it meets the specifications for striking and is exact.
Further Processing
The hub of the Janvier's can be used as an instrument for the making of coins and medals. It's used as a mold or die to create a variety of empty medals or coins with the transferred design.
The Janvier machine's purpose is essential in the process of minting, enabling the replication and reduction of intricate coin or medal designs from master hubs to working hubs with precision. These hubs are utilized to create large amounts of medals and coins by through the strike method.

Why And How Are Certain Types Of Finishes, Textures Or Textured Surfaces Made By Sandblasting?
Sandblasting is an effective technique to create rough or matte surfaces on silver or gold coin and medals. What is the reason and how do we use this method?
Surface Preparation - The coin or medal is put inside a cabinet, chamber or nozzle that is connected to an air compressor. The chamber is typically enclosed to contain the abrasive materials used to prepare the surface.
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 hurled onto the surface of the surface by with compressed gas or a different high pressure system. The force and speed at the point at which particles are thrown on the surface will determine the finish or texture.
Texture Creation: The impact of the abrasive particles on the surface produces a matted or textured look by changing the topography of the surface. The process may be used to selectively roughen specific areas or produce a consistent texture throughout all surfaces.
Controlled Application – Sandblasting's intensity, duration, and angles of application can all be adjusted to create a variety of designs or textures. Different pressure levels and abrasives yield different results.
Sandblasting is used for many reasons
Texture Variation - Sandblasting creates many different textures, which include the grainy, matte and frosted surfaces. They add visual attraction and distinctive characteristics to the medals or coins.
Aesthetics Enhancement - Sandblasting may change the surface's appearance, diffuse light reflection, and even reduce shine. This can enhance the appearance of the medal or coin's aesthetic appeal. Surfaces that are matte, like ones that cut down on glare can highlight specific design details.
Anti-Glare Property - Sandblasting produces smooth or matte surfaces that reduce glare, reflections and makes the item more appealing.
Contrasting Design Elements- Sandblasting creates contrast between textured and polished areas of the medal or coin, emphasizing specific design features or creating depth and dimension.
Sandblasting permits customization, which includes artistic expression and the creation of unique coins or medals that have textures or finishes customized to meet specific design requirements.
Sandblasting is a technique used to create various surface textures or finishes on gold coins or medals. This technique contributes to the aesthetics and visual appeal of these objects.
