How Do You Create The Plaster Cast That Represents A Gold Medal Or Coin?
Gold coins or medal design is utilized as a design reference by the designer or artist. The design could be drawn by hand or a representation created using graphics software for design. There are other materials such as clay or wax.
Plaster preparation- Water is added to the plaster to make it more workable. To ensure a clean mould, the mixture must be smooth and without lumps.
Make the base- The maquette is sculpted on a platform or base. This base could be a wood board or a flat surface that provides stability.
The Maquette is created by using the gold design as a model. The plaster is shaped to create a relief or 3D image of the coin or medal.
Detailing and refinement- The artist concentrates on enhancing details and the contours, and also ensuring the accuracy of features and proportions in the design. This phase requires precision and meticulous attention to the details.
Giving the plaster time to dry out and set- Once a sculpt is finished, it needs some time to set and set. This will allow the maquettes to set and maintain their shape.
Smoothing and Finishing- Following drying, the surface of the maquette is smoothed, then refined to remove any imperfections, bumps, or rough areas.
Sealing and preservationThe sealant or the protective coating is applied on the surface of the maquette to preserve it and prepare it for future processes like molding or scanning.
The 3D plaster model which results can be used to represent the gold pattern on a coin or medal. It is used as a physical reference for the next steps of the production process including scanning for digital replication, creating molds to make mass production, or as a model to allow artists to conceptualize and refine the design before final production.

Loading into vacuum Furnace
The dies are inserted into the vacuum furnace, which is a specialized heat-treating chamber capable of creating the conditions of a vacuum.
Evacuation of Air-
The vacuum furnace removes air from the chamber, creating a controlled vacuum environment devoid of oxygen and other gases. This prevents oxidation and ensures uniform heat treatment.
Heating Phase
The furnace will be heated up to the required temperature in order to harden the dies. The temperature range depends upon the particular material used as well as the method of hardening.
Soaking in high temperature
Die dies need to be kept at the highest temperature for a specified time to allow the material to achieve and maintain its desired hardness.
Cooling or Quenching
Following the soaking phase after which the dies are quickly cooled by using special techniques. This rapid cooling process helps lock in the desired toughness and durability of the metal.
Tempering is an option
In a few cases it is performed after the hardening stage. The dies are heated up to a lower heat to lessen internal stress and improve toughness, while maintaining hardness.
Quality Control and Inspection-
Hardened dies are subjected to rigorous quality inspections and tests to ensure that they meet the specifications for strength, hardness and tolerances for dimensional dimensions.
Post-Treatment Handling-
The dies are then coated or polished and are used to make coins or medals.
The process of vacuum hardening increases the durability, wear resistance, and lifespan of the dies used to create gold coins or medals. This process creates a controlled atmosphere that is free of contaminants from the atmosphere to ensure consistent and reliable hardening.

Reduced Tear and Wear Polishing is a fantastic method to minimize friction and wear when striking. A smooth surface reduces the chance of errors or inconsistencies that are caused to the medal or coin struck by rough surfaces.
Consistency is the key to striking. Hand-polished Diets offer a consistent surface for striking and ensuring uniformity. It is essential to maintain the accuracy, depth, and quality of the design across multiple award or coins.
Die Durability- Well-polished Dies will not break or worn out during the process of striking. They last longer and are more durable, allowing for more strikes, without compromising quality.
Precision and Accuracy Hand polishing enables the engraver fine-tune certain areas of dies, ensuring that the exact details are reproduced on struck coins or medals. The accuracy of a final product is increased due to this level of precision.
Quality Control - Polishing forms an element of a quality control procedure. The examination of the die during hand polishing is a way to spot and correct any flaws or imperfections prior to the striking process.
Surface Finishing- Polishing creates specific textures and finishes that enhance visual appeal, or give unique qualities to coins and medals that have been struck.
