How Does A Janvier Machine Transfer A Gold Coin Or Medal Design From The Master Hub Onto The Working Hub?
A Janvier machine is also called a pantograph, or reduction machine. It's used to transfer the design of a coin or medal from a master into the working center. Here's an 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. To ensure its accuracy, it's typically produced using CNC machineries and other high-precision methods.
Janvier Machine Installation
The Janvier machine includes a stylus, which copies the design from the master hub onto the working one.
The Janvier machine's master hub, which serves as a template to which the design will be re-created, is hung in a secure manner to the machine.
Tracing Design-
The Janvier stylus in the machine captures the contour of the design while it moves across the hub's surface. When the stylus is moved on the hub's surface, it tracks its contours.
Reducing the Design
Simultaneously, the cutting tool of the Janvier machine copies the traced design onto the hub that is working that is typically made of softer material than the master hub, such as nickel or steel.
The cutting tool reduces, or duplicates the design to the hub that is working in a smaller or reduced scale as compared with the hub that is master. This reduces the possibility of striking coins and medals in the desired size.
Precision and Accuracy
Janvier machines operate with precision in order to ensure the exact transfer of design from the master hub to the working hub. It reproduces every aspect and contour accurately.
Quality Control
The final working hub undergoes quality checks to ensure that it conforms to the specifications for striking and is accurate.
More Processing
The Janvier machine produces a functioning hub for the coin and medal striking process. It serves as a die or mold for multiple coins or medals blanks with the transferred design.
Janvier is a crucial component in the process of minting because it has the ability to accurately replicate and reduce intricate designs for coins or medals. The hubs that are working can be utilized in the production process of mass-produced medals or coins.

How Are High-Quality Gold Bars Weighed, Sized And Prepared For Minted?
High-quality gold blanks are meticulously made ready for minting to ensure exact and consistent gold medals or coins. Preparation Process: Gold Material Select- For the creation of blanks, high-purity metal is selected. The gold is refined to meet the purity standards for coins.
Gold Blanks Production- Gold can be made into blanks using the process of blanking or cutting blanks. Blanking involves the cutting of discs and planchets which are coins in size, made from gold using specialized equipment.
Precision Measuring and Weighing
Weighing Every blank is individually weighed to ensure that it satisfies the specifications for the coin. This ensures that the medal or coin contains exactly the right quantity of gold.
Measuringthe diameter, thickness, as well as the overall dimension of each blank are measured using precise instruments to ensure consistency and conformity to the design specifications.
Inspection and Control of Quality
Visual Inspection - Each piece is inspected visually to detect imperfections in the surface, or any irregularities that may affect the final product.
Rejecting Blanks Which Don't Meet Standards- Blanks are rejected if they do not meet weight, size or any other quality specifications. This is to keep the uniformity and consistency.
Justification for the necessity of
Consistency in the Minting Process- Precisely weighed and measured blanks guarantee uniformity during the process of minting. Consistency in weight and dimensions ensures uniformity in the striking process making medals or coins of the same quality and worth.
Accurate Gold Content - Every blank is weighed precisely to ensure that the final coin or medal contains exactly the amount of gold intended. This guarantees accuracy in both value and purity.
Uniform Blanks - Eliminate variations of weight or size which could impact the value of the coin or medal, legality or usability for trade or circulation.
Quality Assurance- Strict quality control measures in the preparation of blanks ensure that only high-quality, defect-free blanks are used in the process of minting, which reduces the likelihood of flaws on the finished product.
Legal Compliance - It's crucial that coins intended for commemorative or circulation purposes adhere to specifications and conform to the legal standards.
The accuracy and reliability in the preparation of gold blanks that are high-quality are essential steps in the minting process.

How Do You Put Gold Blanks Into Coin Presses?
When the production process is completed, gold blanks will be placed in coin presses, where they are stamped with high pressure. They are then transformed into finished medals or coins. Here is an outline of the process for loading blanks.
A feeder system is connected to the coin press. This system loads gold blanks that have been prepared and checked for quality. This feeder system ensures a steady supply of blanks.
Feeding Blanks through the Press
The feeder system introduces blanks into the chamber for striking inside the coin press one at a. This guarantees the exact placement of each stamping blank.
Alignment and Positioning
In the press, the blanks need to be perfectly placed in the strike area to allow the stamping process to occur.
Striving under High Pressure
Coin presses put high pressure on the gold blanks by using a pair dies -- one stationary and the other mobile. The stationary die makes negative marks on the design of the coin while it is moving that die acts as the hammer, which hits the blank.
The die that is moving strikes the blank with considerable force and then transfers the design on the surface of the blank. Die's pressure prints the designs, resulting in the raised reliefs and the details of the medal or coin.
Repetition of Striking Is Optional
For higher-quality coins or medals, especially proof or collector's editions, multiple strikes might be used to create an even more sharp, clear visual or a design. Each strike improves the quality on the surface.
Collection and Ejection
The coins or medals will be released and placed into containers or trays after they've been struck. They are checked for quality control to ensure that designs stamped meet all standards and criteria.
Post-Processing-
If the mint requires it, they may also apply other processes for edge lettering, reeding the edge, or post-strike treatment.
The stamping process under high pressure is vital as it transfers the desired design onto the gold blanks and transforms them into coins or medals ready for use in collection, circulation, or even commemoration. This process requires precision because any deviations in alignment or pressure can affect the appearance and quality of the final product.
