How Does A Janvier Machine Transfer The Gold Coin Or Medal Design To The Hub From The Master?
The Janvier machine, sometimes known as a pantograph, or reducing machine is a machine used in the process of minting that transfers a coin or medal design from a master hub to an operational hub. Here is an overview on how this Master Hub Creation works.
The master hub is the first coin or medal die or mold. The master hub is typically made by using CNC methods of machining or other precision methods to ensure precision.
Janvier Machine Installation
The Janvier machine is comprised of a stylus that traces the design onto the master hub, and cutting tools that copy this design onto the working hub.
The Janvier machine is equipped with an incredibly secure master hub. This is used as a base from which the design can be transferred.
Tracing a Design
The Janvier machine employs stylus that follows the contours and fine details of the design. The stylus tracks the shape of the design as it moves across the hub's surface.
Reduce the Design
Simultaneously, the cutting tool on the Janvier machine reproduces the pattern traced on the hub that is working which is comprised of softer material than the hub used for the master like nickel or steel.
The cutting tool replicates or cuts down the design on the hub that is working to a smaller size or scale compared to that of the master hub. This reduction is vital in the process of minting, because it permits the sculpting of coins or medals at the size you want.
Accuracy and Precision
Janvier's machine is precise and ensures the perfect transfer of details from the master to the working hub. It faithfully reproduces the tiny details and contours.
Quality Control
The resultant hub 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 Janvier can be utilized as an instrument for the making of medals and coins. It is used as a mold, or die to create multiple blank coins or medals with the design transferred.
The Janvier machine's role is crucial for the minting process, enabling the reproduction and reduction of complex medal or coin designs from master hubs to working hubs precisely. These hubs will be utilized to mass produce coins or other medals by using the strike process.

Why Is It Important To Polish Dies Manually For A Perfect Gold Medal Or Gold Coin?
Hand-polishing dies provide smooth and perfect finish for gold coins as well as other medals. Smooth surfaces allow complex details to be more easily replicated on coins and medals.
Improved Quality of the Coin or MedalA die that is polished ensures that the coins or medals have crisp and clearly defined edges, details and relief. This improves the overall aesthetic appeal and overall quality of the product.
Reduced wear and tear Polishing can decrease friction during the striking procedure. A smooth surface minimizes the possibility of mistakes or inconsistencies being caused on the struck coin or medal caused by rough surfaces.
Consistency of Striking - Die dies that are hand-polished ensure uniformity throughout the process of minting, by providing an even striking area. Consistency in design is critical for maintaining precision, depth, or overall quality on a variety of coins and medals.
Die Durability- Well-polished Dies will not get damaged or worn during the striking process. They last longer and are more robust, which allows for larger strikes without sacrificing quality.
Precision and Accuracy. Hand polishing lets engravers precisely fine-tune, refine and even make sure that specific areas are perfect on the die. The details will be accurately depicted on the engraved metal or coin. The level of precision is crucial to the accuracy of the finished product.
Polishing for Quality Control is part of the quality control process. By inspecting the die before polishing by hand allows for identification and rectification of any defects or inconsistencies before striking.
Surface Finish - Polishing is a way to impart a specific surface finish or texture, that can increase the visual appeal of the coins or medals, or give them distinct characteristics.
Hand polishing dies for gold medals and coins by hand is an essential step to ensure that the minted product will be high quality as well as accurate and pleasing on the eye. This is essential to the appearance, durability, and consistency of the final product.

What Is The Process Gold Blanks Being Fed Into Coin Presses, And Stamped Under The Pressure Of High During Minting?
When minting, gold coins and medals are made by pressing them with pressure. Here is a quick overview of the steps in loading blanks.
In the feeder system connected to the press, gold-plated blanks have already been prepared and quality checked. This feeder system ensures that there is a constant supply of blanks to the machine.
Feeding Blanks into the Press-
The feeding system is designed to guide the blanks one at a time into the chamber for striking. This ensures the exact placement of each blank prior to stamping.
Alignment and Positioning
The blanks will be aligned within the press and then placed into the room for striking to ensure they are centered and perfectly aligned to allow for the stamping.
Moving at High Pressure
The coin press exerts high pressure onto the gold blanks with a pair of dies--one stationary and one moving. The stationary die has the negative impressions of the design engraved on the coin. The moving die is used to strike the blank.
The die is moved to strike the blank with a lot of force, and the design is transferred onto the blank's surface. Die pressure causes raised relief and detail on the coin.
Repetition of Striking Is Optional
To produce an image or design that is sharper and clearer, multiple strikes can be used on premium coins or editions of collectibles. Each strike increases the clarity on the surface.
Ejection and Collection
After being struck, newly-minted medals or coins are ejected from the press onto containers or trays. Control of quality is conducted to ensure the designs adhere to specifications.
Post-Processing-
The appearance of the medal or coin may require additional processing for example, edge lettering (either edge reeding) or post-strike treatments.
Stamping gold blanks under high-pressure is essential as it creates the desired design on the blanks of gold. Then, they are transformed into finished medals or coins ready for collection, circulation or commemoration. The process of stamping requires precision as changes in pressure and alignment could impact the final product's quality.
