What Is The Process By Which A Mold Of Plaster Is Made To Be Used As An Initial Physical Representation For The Gold Coin Or Medal?
It is vital to know that the artist or designer will use the gold medal or coin design as a guide. The design could be a sketch made with a pencil, or it could be an image created digitally using graphic software. The wax or clay could also be used.
Plaster Preparation - The plaster is mixed with water to create a smooth consistency that can be manipulated. In order to ensure a clean mould the mix must be smooth and without lumps.
Create the base - The maquette is sculpted on a platform or base. The base can be a board of wood or a flat surface which provides stability.
The Maquette is sculpted by using the gold design as a model. It is the process of shaping the plaster to make a relief or three-dimensional version of the coin or the medal.
Detailing and Refinement - The artist adds details that refine the contours of the image and ensures accuracy in proportions and design elements. Attention to detail and precision are essential at this point.
The time needed for drying and setting- After the sculpting has been done, the sculpted plaster will need to be allowed to dry and set. This is to allow the maquette to harden and keeping its shape.
After drying, it's smoothed and finished to eliminate any imperfections, bumps or rough areas.
Preservation and sealing- A sealant or protective coating can be applied on the maquette's surface in order to preserve it and prepare it for subsequent processes such as molding or scanning.
The resultant plaster maquette acts as a tangible representation of the design of the gold coin or medal. It serves as a physical guide for subsequent stages of production such as digital reproduction, mold making to produce mass quantities or artists to improve and visualize the design before finalizing the.

How Does A Janvier Machine Transfer A Gold Coin Or Medal Design From The Master Hub Onto A Functioning Hub?
A Janvier machine is also known as a pantograph or the reducing machine. It is utilized to transfer the design of a coin or medal from the master to the working center. Here's an overview of the process it uses to accomplish this Master Hub Creation-
The master hub is the die or mold, that has the exact design for the medal or coin. It's made with high-quality CNC cutting.
Janvier Machine Installation
The Janvier machine consists of a stylus that traces the design onto the master hub as well as a cutting tool that replicates the same design onto the operating hub.
The Janvier machine has the master hub that is securely mounted. This is used as a basis upon which the design is transferred.
Tracing Design
The Janvier machine features stylus that is designed to follow the contours, features and shape of the master wheel. When the stylus is moved along the surface of the master hub it tracks the design's shape.
Reduce the Design
The cutting tool of the Janvier machine reproduces the traced design onto the hub that is working that is typically composed of softer materials than the hub used for the master like steel or nickel.
The cutting tools reduce or reproduce the design on the smaller scale or at a smaller size, compared to master hub. This reduction in size is essential to the production of coins and medals, allowing them to be struck in the exact dimensions.
Precision and Accuracy
Janvier’s machine works with precision and guarantees a flawless transfer of design data from the master to the work hub. It faithfully reproduces even the tiny details and contours.
Quality Control -
The resultant hub is subject to quality inspections and examination to make sure that the design is in line with the specifications and accuracy required to strike it.
Additional Processing
The Janvier's hub can be utilized as an instrument for the making of coins and medals. It acts as a mold or die that is used to make numerous blanks for coins or medals that have the design transferred.
Janvier machines are crucial in the creation of medals and coins. They permit the exact reproduction of intricate coins or badge designs.

Why And How Are Some Types Of Finishes, Such As Texture Or Matte Surfaces Achieved By Sandblasting?
Sandblasting is a technique used to produce textured or matte surfaces on gold medals and coins. This is how and why it is used.
Surface preparation- The metal or coin is placed in an enclosure or chamber with a nozzle connected to an air compressor. Abrasive materials are usually stored in this chamber.
Abrasive Materials Selection - At high speeds, tiny particles of abrasive materials, such as silicon carbide (sand) glass beads or aluminum oxide are propelled on the surface of the medal or coin.
High-Pressure Propeller- The abrasive particle is propelled onto the surfaces using compressed air. The speed and force at the point at which particles are thrown on the surface will determine the texture or finish.
Texture creation: By altering the surface's topography by the effect of the abrasive particle, the texture is created. This technique is employed to create a specific roughness in certain areas or create an even texture on the whole surface.
Controlled Application - Sandblasting's intensity length, duration, and angles of application are all controlled in order to achieve various textures or finishes. Different abrasives can create different effects.
Sandblasting is used for a variety of reasons.
Texture Variation Sandblasting is an excellent way to create different textures or finishes on medals and coins, such as matte or frosted surfaces. It can add visual appeal and unique characteristics.
Aesthetic Enhancement: Sandblasting can alter the appearance of the surface, decreasing the shine and diffusing light reflection. This may enhance the aesthetic appeal of the medal or coin. Matte finishes, for example can highlight certain design elements by reducing glare.
Anti-glare Property - Sandblasting creates matte or textured surfaces that minimize reflections, glare and makes the coin or medal more appealing.
Sandblasting Creates Contrasting Design Elements - Sandblasting creates a contrast between the polished and the texture areas of the medal or coin, emphasizing certain design features or giving visual depth.
Sandblasting offers a variety of customization options that allow for artistic expression, and permits medals, coins, or other items to be created with distinct textures or finishes that are unique to the style.
