Available surface finishes
Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact
As-machined
Our standard finish is "as machined" finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.
Material | All materials |
Color | n/a |
Texture | n/a |
Finish | R3.2 |
Bead blasting
Media blasting uses a pressurized jet of abrasive media to apply a matte, uniform finish to the surface of parts.
Material | Aluminum, Steel, Stainless Steel, Brass |
Color | n/a |
Texture | Matte |
Finish | R3.2 |
Anodizing
Anodizing is an electrolytic passivation process that grows the natural oxide layer on aluminum parts for protection from wear and corrosion, as well as for cosmetic effects
Material | Aluminum |
Color | Clear, black, grey, red, blue, gold |
Texture | Matte |
Finish | RA1.2 |
Electroplating
Nickel plating is a process used to electroplate a thin layer of nickel onto a metal part. This plating can be used for corrosion and wear resistance, as well as for decorative purposes
Material | Aluminum, steel, stainless steel, brass |
Color | Gold, silver, nickel, copper, brass |
Texture | Smooth, glossy finish |
Finish | RA1.2 |
Polishing
Parts are manually polished in multiple directions. Surface is smooth and slightly reflective.
Material | Aluminum |
Color | Gold, silver, nickel, copper, brass |
Texture | Smooth, glossy finish |
Finish | RA1.2 |
Powder coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Material | Aluminum |
Color | Custom |
Texture | Glossy |
Finish | RA1.2 |
Brushing
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.
Material | ABS, Aluminum, Brass, Stainless Steel, Steel |
Color | n/a |
Texture | Satin |
Finish | RA1.2 |
Painting
Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer's choosing, while finishes range from matte to gloss to metallic
Material | Aluminum, Stainless Steel, Steel |
Color | Custom |
Texture | Gloss, semi-gloss, flat, metallic, textured |
Finish | RA1.2 |
Black oxide
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance
Material | Aluminum, Stainless Steel, Steel |
Color | Black |
Texture | Smooth, matte |
Finish | RA1.2 |
Alodine
Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivate and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.
Material | Aluminum |
Color | Clear, Gold |
Texture | Smooth, matte |
Finish | RA1.2 |
Part marking
Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production.
Material | All materials |
Color | Clear |
Texture | Smooth, matte |
Finish | RA1.2 |
