What Happens When The Janvier Machine Transfer Gold Coins Or Medals From Master Hubs To The Working Hub?
A Janvier machine is also called a pantograph, or reduction machine. It's employed to transfer the appearance of a coin medal from a master into an operating center. Here's a brief overview of how this Master Hub Creation works.
The master hub, also known as the original mold or die, is the first mold or die which contains the exact layout and design of the coin. It's produced with precision CNC manufacturing.
Janvier Machine Installation
The Janvier machine has stylus, which copy the design from the master hub onto the working hub.
The Janvier machine includes the master wheel which is connected to the machine. It is used as a model to which designs will be transferred.
The process of tracing a design
The Janvier stylus follows the contours of the design and the design details on the master hub. The stylus records the profile of the design when it travels across the hub's surface.
Reduce the Design
The Janvier machine also duplicates the pattern that was traced on the working hub. This hub is typically made from a softer material, such as nickel or steel, rather than the hub used in the master.
The cutting tools reduce or replicate the design at the smaller scale or in a smaller size in comparison to the master hub. This is crucial for the coining process as it permits medals or coins to be made at the desired sizes.
Precision and Accuracy
Janvier's machine operates precisely, ensuring an exact transfer of data from the master hub into the working hub. It is able to reproduce even the smallest details and curves.
Quality Control
The hub that is created is subject to quality checks and examination to make sure that the transfered design meets the specifications and accuracy required to strike it.
Further Processing-
The hub of work created by the Janvier machine is utilized as a tool during the medal or coin striking process. It serves as a die or mold to make multiple medals or coins blanks that have the transferred design.
Janvier is an essential component in the process of minting because it has the ability to precisely replicate and reduce complex designs for coins or medals. These working hubs will then be utilized to mass produce medals or coins striking the process.

How And Why Are Gold Blanks Of High Quality Weighed And Measured Before The Minting Process Starts?
The process of creating gold blanks is meticulously done to make sure that the gold coins or medals made are consistent and precise. The preparation process involves Gold Material Select- For the production of blanks the most pure metal is chosen. The gold is typically refined to meet specific purity standards required for coinage.
Gold Blank Production- The gold is made into blanks using a process called blanking or blank-cutting. Blanking involves cutting coin-sized discs or planchets from the gold material using specialized machines or stamping techniques.
Precision measuring and weighing
Weighing Each piece is individually weighed to ensure that it meets the specified criteria for the coin. This ensures each piece has the exact amount of gold needed for the denomination desired.
Measuring. Precision instruments are used for measuring the diameter, height, and dimensions of each blank. This guarantees the uniformity of measurements and conformity with design specifications.
Inspection and Quality Control
Visual Inspection - Every blank is inspected visually to detect imperfections in the surface, or any irregularities that may influence the final product.
Rejecting Nonconforming Sheets – To ensure uniformity sheets that do not conform to the standards required for weight, dimensions or quality are rejected.
The reasons for preparing
Consistency of the Minting Process - The uniformity of the minting process is ensured by accurately weighing and measuring blanks. Consistency of weight and dimensions results in uniform striking. This results in medals or coins that are the same quality and worth.
Accurate Content of Gold- The exact weight of each blank ensures the coin or medal will have the exact amount of gold designed, ensuring the purity and accuracy.
Uniform Blanks Help Prevent Variations Uniform blanks prevent weight or size variations which could affect the value, legality, and usefulness of a coin or medal in circulation or in commerce.
Quality Assurance – Strict controls on quality during the blank preparation phase ensure that only perfect blanks will be used in the minting process, reducing the chance of having flaws.
Legal Compliance - The coins are intended to be circulated or used for commemorative purposes. They must meet the legal requirements, along with requirements and standards established by regulators or mints.
Preparing gold blanks of high quality and consistency is a crucial step during the coining process. They guarantee the production and accuracy of high-value gold coins and medals.
