Surface Finishing Capabilities
Surface finishing encompasses a broad range of processes that alter the surface of a manufactured part to achieve desired properties. These processes include mechanical finishing (grinding, polishing, lapping, buffing, sandblasting, tumbling), chemical treatments (passivation, chemical conversion, etching), electrochemical processes (anodizing, plating, electropolishing), and coatings (powder coating, painting, PVD/CVD coatings). Surface finishing serves multiple purposes: improving corrosion resistance, enhancing wear resistance, achieving desired aesthetics, preparing surfaces for bonding or painting, and meeting functional specifications. Nearly every manufactured part undergoes some form of surface finishing before reaching the end user.

Surface Finishing in Sioux Falls — FAQ
How many Surface Finishing providers are in Sioux Falls, SD?
The Sioux Falls metropolitan area has approximately 400 manufacturing establishments, many of which offer surface finishing services. The area employs about 12,000 manufacturing workers, ensuring a skilled workforce for your project.
What surface finish should I specify?
The choice depends on function: powder coating for general corrosion protection and aesthetics, anodizing for aluminum parts, plating for conductivity or wear resistance, passivation for stainless steel, and electropolishing for medical and food-contact surfaces.
What is Ra surface roughness?
Ra (Roughness Average) is the most common surface texture measurement, expressed in microinches (μin) or micrometers (μm). Lower Ra values indicate smoother surfaces. As-machined surfaces are typically 32-125 Ra. Ground surfaces achieve 4-32 Ra. Polished surfaces can reach 1-4 Ra.
How do I choose between powder coating and painting?
Powder coating is more durable, environmentally friendly, and provides thicker, more uniform coverage. Wet painting offers more color options, can be applied to heat-sensitive substrates, and allows for touch-ups. Powder coating is generally preferred for metal parts.
Does surface finishing change part dimensions?
Yes, most finishing processes add or remove material. Plating adds 0.0001"-0.003" per surface. Powder coating adds 0.001"-0.003". Anodizing adds approximately half the total thickness to each surface. Account for these dimensional changes in part design.
