Surface Finishing

Polishing, Anodizing, Painting & More
Surface finishing is a processing that can change the finished part's surface to specific color, appearance, property.
It gives the finished part different properties of resistance to corrosion, hardness, conductivity, etc. that out of the material itself.

About Surface Finishing

What Is Surface Finishing?

Surface finishing is the final step in your manufacturing process, enhancing both the appearance and functionality of your parts. Whether you're polishing for a sleek look or coating for durability, our finishing services help bring your product to the next level.

Why Is Surface Finishing Important?

A proper surface finish improves not only the visual appeal, but also the wear resistance, corrosion protection, and overall lifespan of your parts. It ensures your prototypes and end-use products perform as well as they look.

Surface Finishes

As Machined
- Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Mirror Polish
- Grinding the metal part roughly or finely to achieve a smooth and shiny mirror-like surface.
Electropolish
- Electrochemical process that smoothens, polishes, and deburrs metal surfaces to a high gloss.
Alodine
- Chemical treatment process providing corrosion protection and surface preparation for paint adhesion.
Teflon Coating
- Applies a protective layer of PTFE to reduce friction and enhance corrosion resistance.
Heat Treatment
- Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Anodizing
- Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.
Sand Blasting
- Powerfully propels blast media against surfaces to remove coatings and impurities.
Electroless Plating
- Deposition of a metal coating on substrates using an autocatalytic chemical process.
Black Oxidize
- Chemical bath that creates a black oxide coating on metal to improve corrosion resistance.
Spray Painting
- Application of paint for aesthetic improvements and protective coatings.
Powder Coating
- Dry finishing process using powdered paint to provide a high-quality, durable finish.
Nitriding
- Diffuses nitrogen into the surface of metal part to build a hardened surface. It is a heat-treating process.
Electrophoresis
- Coating process using charged particles suspended in a solvent, typically for uniform finishes.
SPI Finish
- SPI Finish standardizes surface textures on plastic parts, offering finishes from high-gloss to matte, ensuring consistent aesthetics and functionality in injection molding.
Brushed Finish
- Mechanical polishing that produces a unidirectional satin finish.
