What Are The Advantages Of Sandblasting Specific Types Of Finishes Or Textures, Such As Matte Surfaces Or Textured Ones?
Sandblasting is an effective technique to create smooth or textured surface on silver or gold coins and medals. This method is used for many reasons.
Surface preparation - The coin or the medal is put inside a cabinet, chamber or nozzle attached to an air compressor. The abrasive materials are often contained within this chamber.
Abrasive Materials Selection- At high speeds, fine particles of abrasive substances like silicon carbide (sand), glass beads or aluminum oxide are propelled on the surface of the medal or coin.
High-Pressure System - The abrasive powders are pushed onto the surface using compressed air, or other high-pressure systems. The speed and force at the point at which particles are thrown on the surface will determine the texture or finish.
Texture Creation. The impact of an abrasive surface alters the topography of the surface to produce a rough, matte finish. It can be used to create a smooth surface, or to create rough texture in certain areas.
Sandblasting can have its intensity, duration and angle controlled to produce different finishes or textures. Different abrasives are employed to achieve different results.
Why you should sandblast
Texture Variation: Sandblasting can allow to create various types of textures and finishes such as matte, frosted, or grainy surfaces that add an aesthetic appeal and distinctive particularities to the metals or coins.
Aesthetic Enhancement - Sandblasting alters the appearance of the surface, decreasing the shine and diffusing light reflection. This can improve the visual appeal of the coin or medal. Matte finishes may help to emphasize certain particular design elements by reducing the the glare.
Anti-glare Property - Sandblasting creates smooth or matte surfaces that reduce glare, reflections and make the medal or coin more attractive.
Contrasting Design Elements. Sandblasting can create contrast between polished and the textured areas on the coin. It can be used to highlight specific design elements or to give them visual depth.
Sandblasting can be customized, which includes artistic expression and creating unique medals or coins that have textures or finishes that are customized to meet certain design requirements.

How Does Gold Get Through The Coin Presses And Then Stamped Under High-Pressure While Minting?
During the production process, gold blanks will be placed in coin presses, which stamp them by high pressure. This transforms them into completed coins or medals. Here's a quick look at loading blanks.
A feeder system is attached to the coin press. The system loads gold blanks that have been prepared and checked for quality. This feeder makes sure that blanks are continuously supplied to the press.
Feeding Blanks in the Press
The feeder system directs each blank to the strike zone of the coin presses. This ensures accurate positioning of each stamping blank.
Alignment of Positioning
Inside the press, blanks are aligned and placed in the chamber for striking making sure that they are perfectly centered and aligned for the stamping process.
Striving Under Pressure
The coin press exerts an intense pressure on gold blanks using two dies: one stationary and one that moves. The stationary die is equipped with negative impressions of the design on the coin. The moving die is used to strike the blank.
The die that is moving strikes the blank with significant force, which transfers the design onto the blank's surface. The force exerted by dies creates the design and creates the raised relief and details on the coin, or medal.
Repeated Striking -
In order to create designs or images that are sharper and more clear, several strikes may be applied on high-quality coins or collectible editions. Each strike improves the surface of the blank.
Ejections and Collection
Following the press's operation, newly-minted medals or coins are ejected out of the press into trays or containers. They are inspected for quality control in order to ensure that the designs stamped meet the specified standards and criteria.
Post-Processing-
Minted coins and medals can undergo additional procedures such as edge lettering, edge reeding, or post-strike treatments depending on the design requirements or mint specifications.
High-pressure stamping that creates designs on the gold blanks is critical and transforms them into finished coin or medals that are used for circulation, collecting or commemoration. The process of stamping requires accuracy as any the variations in pressure and alignment could impact the final product's quality.
