How Can You Achieve Textures Or Matte Surfaces By Sandblasting And How?
This method is employed to give matte or textured effects on gold coins or medals. This technique is utilized to achieve a number of different reasons.
Surface Preparation- The coin or medal is put in the form of a cabinet or chamber with a nozzle that is connected to an air compressor. This chamber is usually enclosed in order to keep the abrasive used in the process contained.
Abrasive Material Selection: Fine particles of abrasive materials, such as sand, silicon carbide, glass beads or aluminum oxide are hurled on the surface of the medal or coin with high velocity.
High-Pressure Propeller: The abrasive particle is propelled onto the surfaces by compressed air. The speed and force at the rate at which particles are thrown onto the surface determines the texture or finish.
Texture Creation - The impact of the abrasive particles on the surface results in a textured or matte appearance by changing the topography of the surface. This can be used either to create an even surface or create rough texture in specific regions.
Controlled application- Sandblasting is controlled by the intensity as well as duration and angle of the application. This allows for a variety of textures and finishes. Different abrasives can produce different effects.
Sandblasting can be used for many reasons
Texture variation - Sandblasting can create a variety of textures and finishes, including matte, grainy, frosted or smooth surfaces. This can add visual interest to coins or medals.
Aesthetic Enhancement- Sandblasting alters the look of surfaces. It helps diffuse light reflections and reduces the shine. This improves the aesthetic appeal of a medal or coin. Matte finishes can be a good example, for instance, they can highlight certain design elements because they can reduce reflections.
Anti-Glare Property - Sandblasting produces matte or textured surfaces that lessen reflections, glare and make the item more attractive.
Contrasting Design Elements. Sandblasting can create contrast between polished and textured ones on the coin. Sandblasting can be used to highlight specific design elements or create visual depth.
Sandblasting is customizable to produce unique textures or designs.
Sandblasting can be used to create various surface textures or designs on gold-plated coins and medals. This technique contributes to the aesthetics and visual appeal of these objects.

How Do You Put Gold Blanks Into Coin Presses?
When minting is completed, gold blanks are fed into coin presses, where they are stamped under pressure to turn into finished coins or medals. Here is a quick overview of the process involved in loading blanks.
A feeder system is attached to the coin press. This system loads gold blanks that are prepared and tested for quality. This feeder system is accountable for maintaining a continuous flow of blanks into the coin press.
Feeding Blanks in the Press
This feeder system ensures that each blank is placed precisely in the stamping chamber. This ensures the exact placement of each blank prior to stamping.
Alignment & Positioning
When using the press, blanks should be placed precisely in the striking area, so that stamping can be completed.
Striking Under High Pressure
The coin presses apply massive pressure on gold blanks with two dies - one stationary and one mobile. The stationary die is the impression of the design that is negative and the die that moves is the Hammer.
Die dies hit the blank with lots of force, transferring the design onto its surface. The pressure of the dies creates the design and the raised relief.
Repeated Striking
Multi-strikes are a great option for more expensive coins or medals for example, like proofs or collector's editions. This results in a sharper and more defined appearance. Each strike helps to refine the details in the blank.
Ejection and Collection
Following the press's operation, newly-minted coins or medals are released from the press onto trays or containers. They are then inspected for quality control to make sure that the designs are in line with all standards and criteria.
Post-Processing-
In accordance with the specifications of the mint or design the coins and medals could undergo additional treatments such as edge lettering, reeding, or post-strike treatments.
Stamping with high pressure etch the desired designs onto gold-plated blanks, and transforms the coins into medals suitable for circulation, collections, or commemoration. The process of stamping demands preciseness as slight the variations in pressure and alignment can influence the final product's quality.
