How Can An Janvier Machine Transfer Gold Coins Or Medals Design To The Working Hub From The Master?
A Janvier, also known by the terms pantograph and reducer machine, is used to transfer a design for a medal or coin from a master hub onto an operational hub. The Master Hub Creation is explained in this video.
The master hub, sometimes referred to as the original die or mould, is the original mold or die which contains the exact layout and design of the coin. It is usually made using CNC machine or other precise methods to guarantee accuracy.
Janvier Machine Setup
The Janvier machine includes a stylus, which copies the design from the master hub onto the working one.
The Janvier machine comes with a master hub which serves as a template for the transfer of design.
Finding the design
The Janvier machine utilizes styluses to trace the contours and detail of the design. The Janvier machine's stylus keeps track of its profile as it moves along the surface.
Reducing the Design
Simultaneously on the Janvier, the cutting tool reproduces the design traced on the central hub of the machine, which is usually composed of a soft material like steel or nickel.
The cutting instruments reduce or reproduce the design on the smaller scale or in a smaller size compared to master hub. This reduction allows for striking coins and medals that are the exact size.
Accuracy and Precision
Janvier machines are operated with precision in order to ensure a perfect transfer of the design from the master hub to the operating hub. It replicates every detail and contour with precision.
Quality Control
The quality of the final hub is inspected to make sure the transfer design meets the specifications required for the striking processes.
More Processing
The hub of work created by the Janvier machine is used to aid in the coin or medal striking process. The die or mold is used to produce numerous coin blanks or medal blanks based on the design that was transferred.
Janvier's machine is essential for coining. It allows for the accurate replication and reduction from a master hub to working hubs of intricate designs.

How Can You Achieve Textures Or Matte Surfaces By Sandblasting And How?
Sandblasting is a method employed to produce certain textures or finishes, such as smooth or textured surfaces on gold medals or coins. Learn more about how and why this method is utilizedProcess of Sandblasting
Surface Preparation - The coin or the medal is placed inside a cabinet, chamber or nozzle attached to an air compressor. Abrasive materials are usually stored in the chamber.
Abrasive Materials Selection- At high speeds, tiny particles of abrasive materials, like silicon carbide (sand) glass beads, or aluminum oxide are carried over the surface of the coin or medal.
High-Pressure Propulsion - Abrasive particles can be delivered to the surface of an object with compressed gas or a different high pressure system. The surface texture is produced by the speed and force of the particles.
Texture Creation - The impact of abrasive powders onto the surface alters the topography, giving it a matte or textured appearance. The process may be used to selectively roughen certain areas, or create a consistent texture throughout the entire surface.
Sandblasting is controlled by the intensity as well as duration and angle of the application. This allows for different types of finishes and textures. Different abrasives and pressure levels produce different results.
Sandblasting for various reasons
Texture Variation - Sandblasting can create a wide range of textures, such as matte, frosted and grainy surfaces. These add visual fascination and unique qualities to medals and coins.
Aesthetic Enhancement - Sandblasting alters the look of the surface, reducing the shine and diffusing light reflection. This improves the visual appeal of the medal or coin. Matte finishes, like they can emphasize certain features of the design by reducing glare.
Sandblasting properties to reduce glare - Through sandblasting, matte or textured surface can be created. This helps reduce glares as well as reflections. The medals and coins are attractive and clearer to view with no light interference.
Contrasting Design ElementsSandblasting can create contrast between polished and textured areas on the medal or coin and medal, highlighting specific design features or creating depth and dimension.
Sandblasting is a great way to customize and make unique designs. It lets you make your mark artistically and create coins and medals with various textures and finishes.
