How And Why Would You Use A Model Of A Plaster To Make A 3d Digital Model Of Gold Coins Or Medals?
The process involves scanning a maquette to create a 3D digital model of gold medals or coins. The equipment used is specially designed to record the specifics and dimensions of the model into a digital version. The digital replica is utilized for a variety of reasons throughout the process of production.
3D Scanning Technology - High-resolution 3D scanners are used to capture the physical dimensions and specifics of the plaster model. They can also capture geometry and measurements by using laser scanning, structured light or other methods.
Surface Information Capture- The scanner emits laser or light beams at the plaster model's surface. The scanner captures any reflections or distortions created by the laser beams and captures the surface details of the model.
Data Collection. As the scanner moves over the model, it collects many data points. The result is a digital representation of the model’s shape contours, details, or contours.
Conversion to 3D Model. Specialized software converts the information into a 3D model. The model is a replica of the physical and dimension of the maquette of plaster.
The Reasons to Create the Digital 3D Model
Digital 3D Models permit precise reproduction of physical models' dimensions and details. This precision is vital in ensuring that the gold coins or medals that are produced match the intended design.

Why Do Dies Used To Strike Gold Coins Or Medals Undergo The Process Of Hardening By Vacuum?
The process of forming dies that are used to create gold coins and medals is achieved by subjecting them to extreme temperatures in controlled conditions inside a vacuum chamber. This article provides an overview of the procedure of vacuum hardening for dies.
When making dies that will be used for striking coins or other medals, it's important that they are free of contamination or residues.
Loading into Vacuum Furnace
The dies are inserted into a vacuum furnace, which is a specially designed heat-treating chamber capable of creating an atmosphere of vacuum.
Evacuation Air
The vacuum furnace eliminates air from the chamber, resulting in the perfect vacuum, free of oxygen and other gases. This guarantees uniform heating and stops the process of oxidation.
Heating Phase
The furnace will be heated to the desired temperature to solidify the dies. The range of temperatures is determined by the specific material and processes for hardening.
Soaking with High Temperatures
The dies must be held at a highest temperature for a specified time to allow the material to achieve and maintain its desired level of hardness.
Quenching or Cooling-
Utilizing specialized techniques that allow dies to be quickly cool down or melted after the soaking process. Rapid cooling assists in locking in desired hardness and strengths in the steel.
Tempering Optional
In certain situations tempering may follow the process of hardening. Tempering is the process of reheating dies at a low temperature to ease internal tensions and improve durability.
Quality Control Inspection
Hardened dies must pass thorough quality inspections and control to attain the desired toughness, hardness, or tolerances.
Post-Treatment Handling-
The dies, after the process of vacuum-hardening is completed, can be further processed like polishing and coating before they are used in strike of coins or medals process.
The vacuum-hardening process improves the durability and wear resistance and longevity of dies employed to make coins or medals. This process creates a controlled atmosphere that is free of contaminants from the atmosphere to guarantee consistent and reliable hardening. It also contributes to the overall quality of the final product.

What Coating Processes Are Used To Shield Gold Coins And Medals?
Here are a few of the different coating techniques used. These are the various kinds of coatings used.
Clear Protective Coatings (Varies). A clear protective coating such as lacquer a specialized plastic, can be applied to protect the surface from oxidation, scratches, or tarnishing. This coating protects and preserves the original appearance of the medal or coin.
Enhancement in Appearance
Gold plating or Gilding - A thin layer of gold can be applied to gold coins or medals. The medal or coin will appear more expensive and lustrous.
Aesthetic Effects
Patinas and antique finishes can be created by using chemical treatments, or coatings. The process is designed to artificially age the surface and creates an aged look that is oxidized.
Colorization or Coloring - Some coins or medals are colored in specific areas using enamels, coatings, or specialized coatings. These colors may be utilized to emphasize certain design elements or to make a contrast.
Anti-Tarnish Coatings-
Anti-Tarnish Solution – If your medal or coin has intricate designs, or specific areas are prone to tarnish, you may wish to apply anti-tarnish solution. These coatings help to prevent discoloration and oxidation over time.
Specialized coatings to protect or authentication-
UV-Reactive Coatings and luminescent Coatings: Some coins or medals are coated with coatings that are UV reactive, which reveal hidden elements or encryptions to ensure security or authentication.
Selective Coatings to Contrast
Selective Coating Removal - In certain cases, coatings are selectively removed from certain regions of the medal or coin to provide contrast between polished and coated surfaces, emphasizing features of the design.
Each procedure has a particular purpose, for instance, to improve the appearance of the metal, protect metal, add security, or achieve certain aesthetic results. These coatings have an enormous impact on the look and durability of gold coins and medals, increasing their value.

Why Do Certain Gold Medals And Coins Have An Antiqued Or Aged Look?
This is how and why it is performed. Here's why and how this is done.
Chemical Patination - The surface of the coin is treated with acids or solutions that result in patina. These solutions may result in controlled tones or oxidation that gives an appearance of age or antique. This is a great way to highlight design details and add depth.
Artificial Aging - Chemical or mechanical techniques can be used to simulate wear and tear that happens with age. Tools and treatments that are abrasive are used to create scratches, scuffs, or worn areas. This can give the medal or coin a aged appearance.
Toning or staining The surface is stained or toned using heat or special solutions. This is a way to mimic the natural discoloration or toning of the skin that happens over time.
Buffing & Polishing Techniques - A particular area is chosen to be polished or buffed in order to eliminate the surface layer or highlight, thereby creating the appearance of wear or aging.
There are many reasons why you should create an antique appearance
Attractiveness to the eye-Some collectors like medals and coins with older appearance due to their aesthetic appeal. The vintage look adds the character, uniqueness and depth to the design.
