Why And How Are Some Surfaces, Such As Texture Or Matte Surfaces Achieved By Sandblasting?
Sandblasting is an effective technique for creating rough or matte surfaces on gold or silver coin and medals. Here's what this technique is and how it is employed.
Surface preparation: The medal, coin or other item is placed inside an enclosed chamber or cabinet with a nozzle that's connected to a compressor. The chamber is typically enclosed in order to keep the abrasive that is used to prepare the surface.
Material selection for abrasive- High speed propulsion of small particles of abrasive materials, such as silicon carbide, sand or glass beads, and aluminum oxide onto the surface.
High-Pressure Propulsion- The abrasive particles are propelled onto the surface by compressed air or another high-pressure system. The force and speed at which the particles strike the surface produce the desired finish or texture.
Texture creation: By altering the surface topography due to the effect of the abrasive particle, the texture is created. This technique can be utilized to create uniform textures or to roughen specific areas.
Controlled Application- Sandblasting may be controlled by intensity, duration, and angle of application in order to create different textures or the appearance. Different abrasives or pressure levels result in different outcomes.
Reasons for Sandblasting
Texture Variation- Sandblasting allows to create various types of textures and finishes including matte, frosted, or grainy surfaces that add visual interest and unique particularities to the metals or coins.
Aesthetics Enhancement - Sandblasting may modify the appearance of a surface as well as diffuse light reflection and decrease shine. This will enhance the appearance of the medal or coin's aesthetic appeal. Matte finishes, for example, may highlight specific features of the design by reducing the glare.
Anti-Glare - A matte surface or textured finish created through sandblasting can reduce reflections or glare. This helps the medals and coins look more attractive, and they are more easily read with no undesirable light interference.
Contrasting Design Elements. Sandblasting produces contrast between polished areas and those that are textured on the coin. It can be used to highlight specific design elements or create visual depth.
Sandblasting is an excellent method to personalize and make unique designs. It allows you to make your mark artistically and create metal and coins in a variety of textures and finishes.
