How Can You Achieve Smooth Or Matte Finishes Using The Process Of Sandblasting? And How?
This method is used for achieving specific textures or finishes that include matte and textured surfaces, on the surface of medals or coins. How and why do we use this method?
Surface Preparation: The coin is placed inside a box or cabinet fitted with an air compressor and an nozzle. The chamber is typically enclosed to keep the abrasive used in the process contained.
Abrasive Material Select - Abrasive particles like glass beads, aluminum oxide silica carbide and sand are propelled at high speed to the surface.
High-Pressure System - The abrasive particles are driven onto the surface with compressed air, or by other high-pressure systems. The surface texture is created by the force and speed of the particles.
Texture Creation- The impact of the abrasive particles on the surface creates a textured or matte appearance by altering the surface's topography. This technique lets you roughen specific areas, or create a texture that's uniform across the surface.
Controlled Application - Sandblasting's intensity as well as the duration and angles of application can all be adjusted to create different textures or finishes. Different pressure levels and abrasives produce different results.
Sandblasting: Why is it necessary?
The process of sandblasting allows the creation of different surface textures, or even mattes, frosted, or grainy surfaces. This creates an aesthetic appeal and adds unique characteristics to coins or medals.
Aesthetic Enhancement - Sandblasting alters the look of the surface, decreasing the shine while also diffusing light reflection. This improves the aesthetic appeal of the coin or medal. Matte finishes be a good example, for instance, they can highlight certain design elements because they minimize reflections.
Anti-glare Property - Sandblasting creates matte or textured surfaces that lessen reflections, glare and make the medal or coin more appealing.
Contrasting Design Elements. Sandblasting produces contrast between polished areas and textured ones on the coin. Sandblasting can be used to highlight certain design elements or to create visual depth.
Sandblasting can be customized to permit artistic expression and also allows medals or coins to be created with distinct textures or finishes that are unique to the design.
Sandblasting creates different textures and finishes on the gold coins and medals. This enhances the overall appeal, appearance and aesthetics.

How Do Gold Blanks Get Fed And Stamped With High Pressure Into Coin Presses During Minting?
In the process of minting gold blanks are loaded into coin presses, where they are stamped under pressure to turn them into finished pieces of gold or coins. This is a brief overview of the steps in loading blanks.
A feeder system is connected to the coin press. The system is loaded with gold blanks that have been prepared and checked for quality. The feeder system is responsible for maintaining a continuous flow of blanks to the coin press.
Feeding Blanks to the Press
The feeder system guides each blank into the zone of the coin presses. The feeder system makes sure that every blank is precisely placed for stamping.
Alignment & Positioning
In the press, the blanks are aligned and positioned in the striking chamber, ensuring that they are perfectly aligned and oriented for the stamping process.
Striking Under High Pressure
The coin press puts an intense pressure on gold blanks with two dies, one stationary and one moving. The stationary die is the negative image of the coin's design and the one that moves is the hammer that strikes the blank.
The moving die hits the blank with a lot of force and transfers the design on the surface of the blank. The dies' pressure imprints the designs, which result in the reliefs raised and the details of the coin or medal.
Repeated Striking -
To produce an image or design that is sharper and better defined, multiple strikes can be used on high-quality coins or collectible editions. Each strike refines the detail inside the blank.
Ejection and Collection-
Once struck, the freshly minted medals or coins are ejected from the press and collected in containers or trays. Stamping designs are then checked for quality control in order to make sure they conform to the standards and requirements.
Post-Processing-
In accordance with the specifications for mint design Coins and medals may undergo additional treatments such as edge lettering or reeding or post-strike treatments.
The stamping process under high pressure is vital as it imparts the desired design on the gold blanks and transforms them into medals or coins that are ready to be used in circulation, collection or commemoration. This process is extremely precise because any alterations in alignment or pressure could affect the appearance and quality of the final product.
