How Does A Janvier Transfer The Gold-Colored Design Of A Coin Or Medal That Is On The Master Hub Onto Working Hubs?
A Janvier Machine, sometimes known as pantograph machines or a reducer is a device employed in the process of coining to move designs from a Master Hub to the Working Hub. This is a brief overview of the Master Hub Creation.
The master hub, also referred to as the original die or mould, is the first mold or die that has the exact layout and design of the coin. It is made using CNC machining, or using other techniques of precision.
Janvier Machine Installation and Setup
The Janvier machine consists of a stylus that traces the design onto the master hub, and a cutting tool that replicates the same design onto the operating hub.
The Janvier machine is equipped with a master hub which serves as a template for the transfer of design.
Finding the design
The Janvier stylus is a perfect match for the design's contours as well as the design details on the master hub. The stylus captures the contour of the design as it moves across the surface of the hub.
Reduced Design-
The Janvier machine also duplicates the pattern traced onto the hub that is in use. The hub is usually constructed from a soft material like nickel or steel, rather than the hub that is used as the master hub.
The cutting tool cuts, or copies the design to the hub that is working at a reduced or smaller dimension compared to the master hub. This is essential in the process of minting, as it allows for the making of coins or medals at the desired size.
Accuracy and precision
Janvier's machine is precise and guarantees a flawless transfer of details from the master machine to the work hub. It faithfully recreates the most intricate details and contours.
Quality Control
The final hub is subject to quality checks to ensure that it meets the specifications for striking and is precise.
Further Processing
The Janvier machine makes a functional hub that is used in the coin and medal striking process. It serves as a die or mold for multiple coins or medals blanks which have the transfer design.
The Janvier machine plays a crucial part in the production process by allowing the exact replication and reduction of intricate designs on coins or medals from a working hub to the master hub. The working hubs are utilized in the mass production of coins or medals by means of the striking process.

What And How Do High-Quality Gold Blanks Are Weighed, Taken Measurements And Then Ready For Minting?
To make gold coins or medals that are precise and consistent gold blanks have to be carefully prepared. This is how and why the process of preparation works. Gold Material Selection: Only high-purity gold can be used to create blanks. The gold is refined until it meets the purity standards needed to be used in coinage.
Gold Blank Production: Gold is transformed into blanks through a process known as blanking or blank cutting. Blanking is the process of cutting discs or planchets to the dimensions of coins gold using special machinery or stamping.
Precision Weighing and Measuring
Weighing. Every blank is individually weighted to ensure it is within the requirements of the coin. This ensures that the medal or coin has exactly the correct amount of gold.
Measurement Instruments - Precision instruments are employed to measure the thickness, diameter as well as the overall dimension of every blank to ensure that it is uniform.
Quality Control and Inspection
Visual Inspection- Each Blank is examined visually in order to detect imperfections in the surface.
Rejecting Non-Conforming BlanksThe blanks that don't meet the minimum dimensions, weight, or quality standards are rejected to keep uniformity and consistency.
Reasons for preparation
Consistency throughout the Minting Process Accurately measured and weighed blanks will ensure uniformity. Weight and dimension consistency ensures uniformity in the striking process and produces coins and medals with the same weight and quality.
A precise gold content- The precise weight of each blank ensures that the final medal or coin has the exact amount of pure and precise gold.
Uniform Blanks Prevent Variations – Uniform blanks help to prevent any weight or size variation that could impact the value, legality, and usability of a coin or medal in circulation or in commerce.
Quality Assurance – Strict quality control of blanks during preparation ensure that only blanks of high-quality and free from imperfections are used during the minting process. This reduces the chances of flaws being present in the final product.
Legal Compliance. It is vital to ensure that every coin, no matter if they are used for the purpose of circulation or to commemorate comply with the requirements and standards set forth by regulatory agencies or mints.
It is important to prepare high-quality gold blanks in a consistent way. This ensures that the gold coins or gold medals created are authentic valuable, legal, and of high quality.

How Are Gold Blanks Put Into Coin Presses Under High Pressure And Stamped?
In the process of minting gold blanks are loaded into coin presses and stamped under extreme pressure to make into finished coins or medals. Here's a quick look at loading blanks.
A feeder system is attached to the coin press. This system loads gold blanks that are prepared and tested for quality. This feeder system is accountable for maintaining a continuous flow of blanks to the machine.
Feeding Blanks to the Press
The feeding system was designed to guide the blanks in one-by-one into the striking chamber. This ensures the precise positioning of each blank prior to stamping.
Alignment and Positioning
Within the press, the blanks are aligned and placed inside the chamber of striking to ensure that they are perfectly aligned and oriented for the stamping process.
Striking under High Pressure
The coin press presses the gold blanks at the highest pressure using two dies, one stationary and another moving. The stationary die has the negative image of the coin's design while the die that moves acts as the hammer that hits the blank.
Die moves and strikes the blanks with great force. This transfers the design onto the surface of the blank. The force of the dies creates the design, as well as the relief is raised.
Repeated Striking is Optional
To produce an image or design that is clearer and more clear, several strikes may be applied on rare coins or collectible editions. Each strike helps to refine the details in the blank.
Collection and Ejection
Once struck, the newly-minted coins or medals are ejected from the press and collected in containers or trays. They are examined for quality control in order to ensure that the designs stamped meet the specified standards and criteria.
Post-Processing-
The design of the coin or medal may require additional processing such as edge lettering (either edge reeding) or post-strike treatments.
Stamping the gold blanks with high pressure is vital since it imprints the desired design on the blanks, transforming them into finished medals and coins that can be used for commemoration, collection or circulation. The process of stamping demands accuracy as any variations in pressure and alignment can influence the final product's quality.
