What Are The Reasons And Methods For Certain Surfaces, Such As Matte Or Textured Surface Achieved Using Sandblasting?
Sandblasting can produce textured or matte surfaces on gold coins and medals. The procedure of Sandblasting is explained.
Surface preparation - The coin or the medal is placed in a cabinet, chamber or nozzle connected to an air compressor. The chamber is typically enclosed to contain the abrasive material used to prepare the surface.
The medal or coin is then coated with abrasive material, which could include sand, glass beads silicon carbide or aluminum oxide.
High-Pressure propulsion: Abrasive particles are delivered to the surface of the surface by with compressed gas or a different high-pressure system. The surface texture is created through the force and speed of the particles.
Texture Creation – The impact of abrasive powders on the surface changes the topography of the surface, resulting in an appearance that is matte or textured. This method is used to create a specific roughness in certain areas or create an even texture across the entire surface.
Sandblasting can have its intensity, duration and angle controlled, resulting in various textures or finishes. Different pressure levels and abrasives result in different outcomes.
Why you should sandblast
Texture Variation - Sandblasting can create a wide range of textures, including matte, frosted and grainy surfaces. They can add fascination and unique characteristics to the medals or coins.
Aesthetic Enhancement - Sandblasting changes the appearance of the surface, reducing the shine while also diffusing light reflection. This can improve the visual appeal of the coin or medal. Matte finishes are a great way to highlight features of the design.
Anti-Glare - A matte surface or textured finish produced by sandblasting reduces reflections and glare. This makes the medals or coins appear more appealing, and they are much easier to read, without undesirable light interference.
Contrasting Design Elements. Sandblasting can create contrast between polished and the textured areas on the coin. It can be used to highlight certain design elements or create visual depth.
Sandblasting offers a variety of customization options that allow for artistic expression and permits medals, coins, or other items to be made with unique textures or finishes unique to the design.
