How And Why Do You Use A Model Of A Plaster To Create A 3d Digital Model Of Gold Medals Or Coins?
Scanning a model made of plaster to create a digital 3D model for gold coins or medals requires specially designed equipment to record the maquette's physical details and dimensions in the digital format. This digital replica is used in a variety of ways throughout the production.
3D Scanning 3D scanners with high-resolution are utilized to capture all details and dimensions of the model. The scanners employ various techniques like laser scanning and structured light to capture exact dimensions and geometrical shapes.
Capturing information about the surface- The scanner emits light beams or lasers at the model. The reflections or distortions caused by these beams are captured by the scanner, capturing the model's surface information.
Data Collection - As the scanner travels across the surface of the model, it collects a vast amount of data points, which creates a digital representation of the model's shape as well as contours and other details.
Conversion into 3D Model- The collected data points are processed by special software that converts the information into a 3D digital model. This model reproduces the physical properties and dimensions of a maquette made of plaster.
There are a variety of reasons to make a 3D digital model
Digital 3D models are precise in reproducing the dimensions and details of real models. It is crucial to keep this precision to make sure that the design and style of the gold medal or coin is in line with the original.
Digital models can easily be modified or upgraded. Designers can modify the 3D models without changing their initial plaster model.
Compatible with manufacturing processes Digital 3D designs are compatible with various manufacturing techniques like CNC machining or 3D Printing, making it easier to produce molds or dies for the mass production.
Documentation and Archiving Digital 3D models are an archived record of the design. They can be saved digitally to be used in the future for references, reproductions, or historical documentation purposes.
By scanning a plaster model and creating a precise digital 3D model, producers and designers are able streamline production, improve accuracy, and use modern manufacturing techniques to create gold-plated coins and medals with accuracy.

What Does An Janvier Machine Transfer The Design Of The Gold Coin To A Working Hub?
A Janvier is also known under the name pantograph or reduction machine, is employed to transfer designs for a medal or coin from a master hub to a working hub. The Master Hub Creation is explained in this video.
The master hub is the primary coin, medal or coin mold. It is usually made using CNC machine or other precise methods to ensure precision.
Janvier Machine - Setup
The Janvier Machine is comprised of two components: a stylus to trace the design and a cutting tool which cuts the design.
The hub master is securely fixed to the Janvier machine, serving as the template from which the design will be transferred.
Tracing a Design
The Janvier machine's stylus records the contour of the design as it moves along the hub's surface. The stylus on the Janvier machine keeps track of the profile when it moves on the surface.
Reducing Design-
The Janvier machine can also reproduce the pattern that was traced onto the hub that is in use. The hub is usually composed of softer materials like nickel or steel, as opposed to the hub used in the master.
The cutting tool reduces or copies the design onto the hub of the working wheel in a smaller dimension or size compared to the hub that is the master hub. This reduction is essential for the coining process as it allows coins or medals to be made at the desired sizes.
Precision and Accuracy
The Janvier machine operates precisely to ensure an exact transfer of the layout from the master hub to the operating hub. It faithfully reproduces even the most intricate details and contours.
Quality Control
Inspections and quality checks are performed to verify that the design transferred matches the requirements and accuracy needed to strike the design.
Further Processing
The Janvier machine's working hub can be used to strike coins or medals. It's used as a mold or die to create multiple blank coins or medals with the design transferred.
Janvier's machine is essential in the coining process. It allows for the precise replication and reduction of a master to working hubs for intricate designs. These hubs will be used to create mass production of coins or other medals by using the strike process.
