|  | The "as machined" finish is the standard we use for parts. This kind of finish removes all sharp edges and deburrs parts, with a surface roughness of Ra 3.2 μm (126 μim). There might be obvious tool marks on the surface. Please take note that this finish satisfies the non-cosmetic availability requirements. | All materials | N/A | Stain | ||
|  | Anodizing preserves the metal's surface while increasing hardness, corrosion resistance, and wear resistance. | Aluminum | Gold, blue, clear, black, red, grey | Matte smooth finish | ||
|  | The surface of the parts or product is given a matte finish. It is primarily used for aesthetic purposes. | Steel, Stainless steel, Aluminum, ABS | N/A | Matte | ||
|  | This surface treatment technique uses rough belts to leave marks on a material's surface. This is typically done for aesthetic purposes. | Steel, Stainless Steel, Aluminum, Brass, Copper | N/A | Stain | ||
|  | This includes both decorative and functional options. Another example is electroplating, which involves manipulating properties with electrical tools. | Stainless Steel, Steel, Aluminum | Black, Grey, Clear, Gold, Blue, Red | Glossy, smooth finishh | ||
|  | Polishing involves rubbing or using chemicals to create a smooth, shiny surface on an object. | Steel, Brass, Stainless Steel, Aluminum | N/A | Glossy | ||
|  | Powder coatings employ a free-flowing, dry powder. Powder coatings are electrostatically applied and hardened using heat or UV. | Steel, Stainless Steel, Aluminum | Black, Pantone number, or RAL code | Semi- glossy or glossy | ||
|  | Coatings can be applied to die castings to enhance color, texture, or protect them. Paint finishes vary from basic painting to advanced techniques like electrostatic painting and dipping. | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Semi- glossy or glossy | ||
|  | Chrome plating involves applying a thin layer of chromium to the surface of die castings through electroplating. This process results in a shiny, reflective finish with excellent corrosion resistance. | Stainless Steel, Steel, Aluminum | Black, Grey, Clear, Gold, Blue, Red | Semi- glossy or glossy | ||
|  | Custom finishes are available for a variety of materials and applications. | All materials | N/A | N/A | ||
