Why And How Is An Image Made From Plaster Converted To Create A Digital 3d Representation For Gold Medals Or Coin?
This process makes use of specially designed equipment to digitize a maquette and capture its dimensions. This digital replica serves multiple purposes during the production process.
3D Scanning: High-resolution 3D scanners are employed to capture all dimension and details of the model. These scanners capture measurements and geometry using various methods such as laser scanning or structure light.
Capturing Surface Information - The scanner emits laser or light beams onto the surface of the model. The scanner captures the surface data of the model by recording the reflections, distortions, and other effects caused by laser beams.
Data collection- The scanner gathers data when it moves over the model. This produces an electronic representation of the model's contours, geometrical details and more.
Conversion to 3D Model - The data points taken are processed by software which reconstructs them into a 3D digital model. The model is a replica of the physical features and dimensions of the plaster maquette.
The Motives for Creating the Digital 3D Model
Digital 3D Models permit exact reproduction of physical models' dimensions and details. This ensures that the final gold coins as well as medals are made to conform to the original design.
Digital models may be easily altered or refined. Designers can modify the 3D model, without changing the plaster model in its original form. This allows for repeated adjustments or enhancements.
Compatibility with Manufacturing Processes- Digital 3D models are compatible with a variety of manufacturing techniques like 3D printing or CNC machining and enables the creation of molds and dies for mass production.
Archiving and Documentation - Digital 3D models function as an archived documentation of the design. They can be digitally stored for future references, reproductions, or historical documentation purposes.
By scanning the plaster model and creating digital 3D models designers and manufacturers can streamline the production process and ensure precision in reproduction and make use of the latest manufacturing technologies to make gold coins or medals with precision and fidelity to the original concept.

How Does The Janvier Machine Transfer Gold Coins Or Medals Design To The Working Hub From The Master?
The Janvier machine (also called pantographs or reduction machines) is a specific device that can transfer a coin design or medal from the master hub to the operational hub. The Master Hub Creation is explained in this video.
The master hub is the original die, or mold, that has exactly the design of the medal or coin. The majority of them are made by CNC machine or other precise methods to guarantee accuracy.
Janvier Machine Installation
The Janvier machine consists of a stylus which trace the design onto the master hub as well as cutting tools that copy the design on the working hub.
The Janvier machine is fitted with a master hub which acts as a template to guide the transfer of design.
The design is traced
The Janvier machine utilizes styluses to trace the contours and fine details of the design. The stylus on the Janvier machine records the profile as it moves along the surface.
Reduce the Design
Simultaneously, the cutting tool of the Janvier machine copies the design traced onto the working hub that is typically made of softer material than the hub used for the master like steel or nickel.
The cutting tool duplicates or reduces the design of the hub that is working to a smaller size or scale as compared to the master hub. The smaller size is critical in the making of medals and coins making them possible to strike at the right dimensions.
Precision and Accuracy
Janvier's machine operates with precision and ensures a perfect transfer of details from the master to the hub. The machine can reproduce even the tiniest details and contours.
Quality Control
Inspections and quality checks are conducted to confirm that the design is in line with the specifications and accuracy required for the striking process.
Further Processing
The Janvier's hub can be used as an instrument in the striking of coins and medals. It serves as a mold or die to make multiple medals or coins that are blank and have the transfered design.
The Janvier machine plays an important role in the minting procedure, as it allows the exact replication and resizing of intricate designs on coins or medals from a hub that is working to the master hub. These hubs are used to produce large quantities of coins and medals using the striking method.

Why Are Dies Cleaned By Hand To Guarantee A Flawless Surface For Gold Coins And Medals?
Hand-polishing tools ensure smooth and perfect surface for gold coins and other medals. A smooth surface permits intricate details to be easily replicated on medals and coins.
The polished die ensures that the medals and coins struck have sharp edges, well-defined details and relief. It increases the aesthetics and quality of your final product.
Reduced Tear and Wear Polishing is an excellent way to reduce friction and wear when striking. A smooth die's surface minimizes the likelihood of defects or irregularities on the struck coins or medals due to rough surfaces of the die.
Consistency of Striking – Hand-polished dies ensure uniformity during the process of minting, by providing an even strike area. Consistency in design is critical to ensure accuracy and depth or overall quality of multiple coin and medals.
Longevity and durability of DiesDies with a high polish are less prone to damage or wear while striking. They're more durable and endurance, which allows to make more strikes without damaging the quality of minted products.
Accuracy and Precision Hand polishing enables the engraver to fine tune specific areas of the die, making sure that the exact details are reproduced on medals or coins struck. This accuracy is essential for the precision of the final product.
Quality Control - Polishing is a element of quality control. The examination of the die while polishing by hand is a method to spot and correct any imperfections or defects prior to the process of striking.
Surface Finish- Polishing can give particular surface finishes or textures, enhancing the visual appeal or adding unique characteristics to the coins or medals.
Hand polishing the dies of gold coins and medals by hand is an essential step to ensure that the minted product will be of the highest quality, accurate, and pleasing on the eye. It is a significant factor in the appearance of the final product, reliability, and longevity.

How Are Gold Blanks Supplied And Stamped With High Pressure In Coin Presses During Minting?
When minting the gold coins and medals are created by pressing them under pressure. Here's a brief outline of the process for loading blanks.
In the feeder system linked to the press, the gold blanks are prepared prior to the press and quality checked. This feeder system assures a steady flow of blanks.
Feeding Blanks to the Press
The feeder system directs the blanks one at a time into the chamber of striking for the coin press. The feeder system ensures that each blank is placed precisely to be stamped.
Alignment and Positioning
The blanks are aligned in the press and placed in the room for striking, making sure they are in the right place and placed to enable the stamping.
Fighting Under Pressure
The coin press has two dies: one stationary, and the other one moves. The stationary die has the negative impressions of the design on the coin, and the moving die strikes the blank.
The die moving transfers the design from the blank onto its surface with considerable force. The force of the dies creates the design as well as the raised relief.
Repetition Striking (Optional)-
For higher-quality coins or medals such as collector's or proof editions, a variety of strikes can be applied to achieve a sharper, more defined image or design. Each strike helps to refine the details in the blank.
Ejections and Collection
The newly struck coins or medals will be removed and put in containers or trays when they have been struck. They undergo inspection for quality control to make sure that the designs are in line with the specifications and standards.
Post-Processing-
The appearance of the medal or coin might require additional processing like edge lettering (either edge reeding) or post-strike treatment.
Stamping the gold blanks with the highest pressure is crucial because it prints the desired design on them, making them refined coins and medals that can be used for celebration or collection purposes, or for circulation. This process requires precision because any variations in alignment or pressure could impact the appearance and quality of the end product.
