How Is A Plaster Replica Scanned In Order To Create An Accurate Digital 3d Model Of Gold-Plated Medals Or Coins?
The process of scanning requires specially designed equipment that records the plaster maquette in digital format. This digital copy is used for a variety of uses during production.
3D Scanning Technique- High resolution 3D scanners are able to record dimensions and other details on models of plaster. They employ a variety of techniques like laser scanning and structured light to capture exact dimensions and geometrical shapes.
The scanner emits light or lasers beams to the surface plaster models. The scanner captures the surface data of the model by recording reflections, distortions and other effects caused by the beams.
Data collection - The scanner collects data as it travels across the model. This results in a digital representation that includes the contours of the model, its geometry and details.
Conversion into 3D Model - The data points that are collected are processed by a software that reconstructs them into a 3D digital model. This model reflects the physical dimensions and features of the plaster maquette.
There are a variety of reasons to make 3D digital models
Digital 3D replicas are accurate in recapturing the dimensions and features of the physical models. This accuracy ensures that the gold medals and coins will match the design.
Digital models may be easily altered or refined. Designers can alter the 3D model, without changing the plaster model in its original form. This allows for iterative corrections or improvements.
Compatibility with Manufacturing Processes- Digital 3D models are compatible with different manufacturing processes like CNC machining or 3D printing which makes it easier to create molds or dies for mass production.
Digital 3D models are used as a reference for the design. They can be stored digitally to be used in the future for references, reproductions or for historical documentation.
Designers and producers can make use of advanced manufacturing techniques to produce gold medals and coins which are exact and faithful to the original designs by scanning models of plaster and creating digital 3D models.

What Are The Advantages Of Using Laser Technology In The Refinement Of The Gold Coin Die, Or Master Hub?
Laser technology in the production of dies or master hubs can be utilized to improve the surface and improve precision. Here's a look at how laser technology is utilized to achieve this. Surface Refinement
The master hub's surface is re-polished using laser technology after the initial milling. It can smooth out imperfections or remove burrs.
Detail Enhancement-
Laser ablation and engraving are used to create or enhance details on the master hub or die. Lasers allow for precise removal or etching of materials, allowing the creation of intricate lines, textures or complex patterns.
Microstructuring-
Laser microstructuring involves the creation of microscopic patterns or textures on the die's surface. This technique allows for the creation of specific patterns or textures that improve the appearance as well as security features on coins and medals.
Surface Hardening Treatment, also known as Hardening
Laser technology can be utilized in some cases to treat or harden dies or master hubs. This process improves the wear resistance and durability that ensures the longevity of the process of striking.
Precision Modifications
Laser technology is an exact way to modify or modify the die or master hubs, with no change to the geometry. The ability to alter the surface of the die to fix imperfections, imperfections and other problems that may influence the quality of struck medals or coins.
Controlled Material Removal
Laser ablation is utilized for controlled removal of materials, especially in areas where intricate particulars must be outlined or adjusted. The material is removed by contact, thus preserving the integrity of the area.
The use of the laser to enhance and refine the features on master hubs and dies provides a greater degree of precision and more precise details. Additionally, it enhances the quality of the surface. Laser technology allows for precise manipulation of the surface and improves its properties, which is essential to produce high-quality coinage or gold medals.

What Coating Processes Are Used To Shield The Gold Of Medals And Coins?
The coating process is utilized to safeguard, improve the appearance, or achieve certain aesthetic effects. Here are some different coating techniques.
Clear Protective (Varies). A protective clear coating like lacquer can be used to protect surfaces from the effects of oxidation. This coating protects and preserves the original appearance of the medal or coin.
Enhancement of appearance
Gold plating, also known as gilding- The surface of a gold coin or medal could be covered with a fine layer of of gold. This provides a stunning look to the coin or medal.
Aesthetic effects
Antique finishes and patinas can be made by chemical treatments, or coatings. The process results in the appearance of a surface that is aged and oxidized.
Colorization / Coloring - In some cases, the color of specific areas of a coin, medal, or other item can be achieved through the use of specialized coatings and enamels. The purpose is to improve design elements that create contrast, as well as increase the visual appeal.
Anti-Tarnish Coatings-
Anti-Tarnish Solution: If your medal or coin features intricate designs or specific areas are prone to tarnishing you may want to apply anti-tarnish products. These coatings can prevent oxidation or discoloration of the metal surface over time.
Specialized Coatings to Protect or Authentication-
UV-Reactive Coatings. Some metals and coins are coated with a specific UV-reactive coating that reacts to UV light. It can reveal hidden components such as security codes or encryption.
Selective Coatings for Contrast
Selective Coating Removal - Some coins and medals have their coatings removed from specific areas to create a contrast between the polished and coated surface. This highlights design elements.
Each procedure serves a specific objective, be it to safeguard metals, enhance appearance, create certain aesthetic effects, or increase security. These coatings have an enormous impact on the appearance and durability of gold medals and coins, increasing their value.
