What Are The Best Ways To Achieve Matte Or Textured Finishes Through Sandblasting And How?
This method can be used to creating specific textures or finishes that include matte, textured, or patterned surfaces on coins or medals. Learn more about the process and how it is employed.
Surface preparation. The coin or medal is placed inside a chamber with an air-compressor-connected nozzle. The abrasive materials are often contained in the chamber.
Abrasive Material Selection: Fine particles of abrasive material, such as sand, silicon carbide, glass beads, or aluminum oxide are propelled on the surface of the medal or coin with high velocity.
High-Pressure Propeller- The abrasive particle is launched onto surfaces by compressed air. The surface texture is produced through 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 changing the topography of the surface. This technique can be utilized to create an even texture or roughen particular areas.
Sandblasting that is controlled - Sandblasting can be controlled by intensity, duration and the angle of the application. This permits different types of finishes and textures. Different abrasives are used to create different effects.
Sandblasting for various reasons
Texture Variation - Sandblasting can create a wide range of textures, including matte, frosted and grainy surfaces. These add visual attraction and distinctive characteristics to the medals or coins.
Aesthetic Improvement- Sandblasting alters the appearance of a surface. It diffuses light reflections and reduces the shine. This increases the aesthetic appeal of a medal or coin. Matte finishes are a great way to highlight features of the design.
Anti-Glare - A matte surface or textured finish that is created by sandblasting reduces reflections or glare. This helps the medals and coins look more attractive, and they are easier to read without any unwanted light interference.
Contrasting Design Elements. Sandblasting can create contrast between polished areas and textured ones on the coin. Sandblasting can be used to emphasize specific design elements or to give them visual depth.
Customization and Creativity- Sandblasting offers customization options, allowing for creative expression as well as the creation of medals or coins with distinctive textures or finishes tailored to specific design requirements.

How Do Gold Blanks Get Fed And Stamped With High Pressure In Coin Presses During Minting?
In the process of minting gold medals and coins are produced by stamping them under pressure. This is a brief overview of the process of loading blanks.
The gold-colored blanks are inserted into the feeder system, that is connected to coin presses. This feeder ensures that the blanks are always delivered to the press.
Feeding Blanks in the Press
The system of feeding is designed to move the blanks in one-by-one into the chamber for striking. This allows for precise placement of each blank prior to stamping.
Alignment and Positioning
Within the press, the blanks are aligned and positioned inside the chamber of striking, ensuring that they are perfectly centered and aligned to allow for the stamping process.
Striking Under Pressure
A coin press applies pressure to gold blanks with two dies, one stationary and the second moving. The stationary coin die provides a negative image of the coin's design. The moving die is used as a hammer to hit the blank while the stationary one contains the positive impression.
The die moving transfer the design of the blank to its surface using a lot of force. The pressure exerted by the dies creates the design which creates the relief raised and specifics on the coin or medal.
Repeated Striking Optional
Multi-strikes can be used to create more expensive coins or medals like proofs or collectors' editions. This will result in an improved and clearer appearance. Each strike improves the fine details on the outside of the coin.
Ejection and collection
The coins or medals are removed and put in containers or trays when they have been struck. The stamping designs are examined for quality control to ensure they conform to the standards and standards.
Post-Processing-
Minted coins and medals can undergo additional procedures like edge lettering, edge reeding or post-strike treatment based on the design requirements or specifications for mints.
Stamping under high pressure imparts the desired designs onto the blanks of gold, transforming them to finished coins or medals that are suitable for circulation, collections or even commemoration.
