As machined (Ra 3.2μm / Ra 126μin)
This finishing option has the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.

| Texture | n/a |
| Material | All materials |
Smooth machining (Ra 1.6μm / Ra 63μin)
Smooth machining is similar to an ‘As machined’ finish but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.
| Color | n/a |
| Texture | n/a |
| Material | All materials |
Polishing (Ra 0.8μm / Ra 32μin or better)
Polishing is creating a smooth and shiny surface by rubbing it or applying a chemical treatment.
| Color | n/a |
| Texture | Smooth, glossy finish |
| Material | All materials |
Bead Blasting
Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.
| Color | Uniform matte of raw material color |
| Texture | n/a |
| Material | Aluminum, Stainless Steel, Steel, Brass, Copper |
Tumbled
It is a process that tumbles vibrating media on machined parts to remove sharp edges and burrs.
Tumbling can be used to remove machine marks from exterior surfaces.

| Texture | n/a |
| Material | Aluminum, Stainless Steel, Steel, Brass, Copper |
Bead blasted + Anodizing type II (Matte)
The parts are bead blasted to #120 grit before being anodized type II—ideal for increasing the part’s corrosion resistance and cosmetic effects. As a result, the colors are naturally matte.
Anodizing Type II film thickness is 8-12 μm (clear) or 12-16 μm (black/color).
| Color | Clear, black, blue, red, gold, or any RAL code or Pantone number |
| Texture | Grit #120 |
| Material | Aluminum |
Bead blasted + Anodizing type II (Glossy)
The parts are bead blasted to #120 grit, and then anodized type II with bright dipped. The result is a glossy color. Ideal for cosmetic parts that require increased corrosion resistance.
Anodizing Type II film thickness is 8-12 μm (clear) or 12-16 μm. (black/color).
| Color | Clear, black, blue, red, gold, or any RAL code or Pantone number |
| Texture | Grit #120 |
| Material | Aluminum |
Bead blasted + Anodized type III (Hardcoat)
The parts are bead blasted to #120 grit before being anodized type III. Type III (Hard Coat) is thicker and adds a wear-resistant layer to Type II’s corrosion resistance, suitable for functional applications.
Anodizing Type III film thickness is 25-50 μm.
| Color | Nature, black or other colors |
| Texture | Grit #120 |
| Material | Aluminum |
Powder Coated
This is a finish of applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods. A wide range of colors is available to achieve the desired aesthetic.
| Color | Black, green, blue, red, or any RAL code or Pantone number |
| Texture | Glossy or Sand |
| Material | All metal materials |
Black Oxide
Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.
| Color | Black |
| Texturen/a | n/a |
| Material | Steel, Stainless Steel |
Chromate Conversion Coating (Alodine/Chemfilm)
Chromate conversion coating is used to improve the corrosion resistance of aluminum and aluminum alloys while keeping their conductive properties. It is also applied as a base layer prior to priming and painting parts.
| Color | Clear, Gold |
| Texturen/a | n/a |
| Material | Aluminum |
Plating
Include Nickel Plating, Silver Plating, Gold Plating, Zinc Plating, Chrome Plating, Tin Plating, etc, it is ideal for reducing corrosion, and improving the appearance and function of solderability, and electrical conductivity.
| Color | Custom |
| Texturen/a | Smooth, glossy finish |
| Material | Aluminum, steel, stainless steel, brass |
DLC (Diamond-Like Carbon) Coating
DLC (Diamond-Like Carbon) coating is a hard, wear-resistant coating made of a carbon-rich material that exhibits some of the properties of diamonds.
| Color | Black |
| Texturen/a | typically smooth and hard |
| Material | Stainless steel, Titanium and its alloys, Aluminum and its alloys, Copper and its alloys, and Nickel and its alloys |
Finishing options
| Finishing Method | Appearance | Corrosion Resistance | Wear Resistance | Typical Use Case |
