What Are The Advantages Of Sandblasting Certain Types Of Finishes Or Textures, Such As Matte Surfaces Or Textured Ones?
Sandblasting is an effective technique to create rough or matte surfaces on gold or silver coins and medals. This is the reason and how it's usedProcess for Sandblasting
Surface preparation- The coin, medal or other piece of material is placed in an enclosed compartment or cabinet equipped with an nozzle connected to compressor. 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 hurled at high velocity onto the surface.
High-Pressure Propulsion - The abrasive particles are driven onto the surface by compressed air or a different high-pressure system. The force and velocity at which the particles hit the surface produce the desired texture or finish.
Texture creation- By altering the surface's topography by the impact of the abrasive particles creating a texture. This technique is employed to siftly roughen certain areas or create an even texture over the whole surface.
Controlled Application: Sandblasting's strength, duration, and angles of application can be adjusted to create different textures or finishes. Different pressure levels or abrasives yield different results.
Sandblasting can be used for many reasons.
Texture variations- Sandblasting permits the creation of different textures or surfaces such as mattes, frosted or rough surfaces. This can create an aesthetic appeal and adds unique characteristics to the coins or the medals.
Enhances the aesthetics of a surface - Sandblasting can change the surface's appearance and reflect light in a diffuse manner and reduce shine. This will enhance the appearance of the medal or coin's aesthetic appeal. Matte finishes, for instance can highlight certain designs by reducing the reflections and glare.
Anti-Glare - A matte or textured finish produced by sandblasting will reduce reflections or glare. This makes the coins or medals look attractive and they are easier to read without any undesirable light interference.
Contrasting Design ElementsSandblasting can create contrast between polished and textured areas of the medal or coin to highlight specific design elements or creating visual depth and dimensionality.
Customization and Creativity - Sandblasting provides a variety of customization options, which allows for creative expression as well as the creation of coins or medals with distinctive textures or finishes customized to meet specific design specifications.
