What Is The Process By Which A Janvier Machine Transfer A Gold Coin Or Medal Design To The Working Hub Of The Master?
The Janvier Machine, also referred to as a pantograph machine or a reducer, is a machine employed in the process of coining to transfer designs from a Master Hub an Working Hub. This is a brief overview of the Master Hub Creation.
The master hub is the first coin or medal die or mold. The majority of them are made by CNC machine or other precise methods to ensure precision.
Configuration for Janvier MachineSetup for Janvier Machine
The Janvier Machine consists of two parts: a stylus to trace the design and a tool that cuts out the design.
The Janvier machine comes with a master hub, which acts as a template to guide the transfer of the design.
Tracing The Design
The Janvier machine's stylus records the profile of the design as it travels along the surface of the master hub. As the stylus moves across the surface of the master hub it keeps track of its shape.
Reducing Design-
The Janvier machine also replicates the traced pattern on the working hub. The hub is usually composed of softer materials, such as nickel or steel, rather than the hub that is used as the master hub.
The cutting tool replicates or cuts down the design on the working hub to a smaller size or scale in comparison to the hub that is master. This is crucial for the minting procedure, as it allows for the making of medals or coins at the desired size.
Accuracy and precision
The Janvier machine operates with precision to ensure precise transfer of the design from the master hub to the work hub. It accurately reproduces all details and contours, even the smallest of them.
Quality Control
The working hub will undergo inspection and quality control to ensure that it is in line with the specifications and accuracy for the striking procedure.
Further Processing-
The hub of the Janvier's is a useful tool for striking coins and medals. It is used as a mold or die for creating multiple coin or medal blanks with the transfer design.
The Janvier machine's function is vital for the minting process it allows the replication and reduction of complex medal or coin designs from a master hub to working hubs accurately. The working hubs can be used to create mass production of coins and other medals using the strike process.

How Do You Get Smooth Or Matte Finishes Using Sandblasting? How?
This method can be used to creating specific textures or finishes, such as matte, textured, or patterned surfaces, for the surface of medals or coins. This is how and why it's usedProcess for Sandblasting
Surface preparation: The medal, coin or other item is placed in an enclosed compartment or cabinet that has the nozzle which is connected to compressor. The chamber may be enclosed in order to protect the abrasive material used during the procedure.
Abrasive material selection - High speed propulsion of fine particles of abrasive abrasives, like silicon carbide or sand, or glass beads and aluminum oxide on the surface.
High-Pressure: The abrasive grains are driven onto the surface using compressed air or by another high-pressure device. The force and speed at which the particles strike the surface create the desired finish or texture.
Texture Creation - The impact of abrasive powders on the surface alters the topography, creating the appearance of textured or matte. This technique can be utilized to create uniform textures or to roughen specific regions.
Controlled Application- Sandblasting can be controlled in terms of intensity, duration, and angle of application in order to create different textures or finish. Different abrasives may produce distinct effects.
Reasons for Sandblasting
Texture variation - Sandblasting can produce a variety of different textures and finishes, including glossy grains, frosted, or grainy smooth surfaces. This adds visual interest to coins or medals.
Aesthetic enhancement- Sandblasting can alter the surface appearance by diffusing light, and thus reducing shine. This could enhance the appeal of the coin. Matte finishes can be a good example, for instance, they can highlight particular design elements since they minimize glare.
Anti-Glare Properties- Matte or textured surfaces produced through sandblasting can help reduce glare and reflections, making the medals or coins more visually appealing and easy to see without interference from light.
Contrasting Design Elements. Sandblasting can create contrast between polished and those that are textured on the coin. It is a great way to highlight specific design elements or to give them visual depth.
Sandblasting can be personalized to create unique designs or textures.
