Surface Finishes for Your Choosing

Name Description Materials Color Texture Link
surface finish brushing
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. ABS, Aluminum, Brass, Stainless Steel, Steel n/a Stain Learn more
surface finish bead blast

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

surface finish powder coating
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. Aluminum

surface finish painting
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.

surface finish polishing
Polishing

Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements.
