Perfect Your Project’s Finish

From aesthetic brilliance to functional durability, our comprehensive surface finishing services ensure your parts meet the highest industrial standards.

As Machined

Standard finish with surface roughness of 3.2 µm (126 µin). Removes sharp edges and deburrs parts cleanly.

METALS · PLASTICS
Anodizing (Type II & III)

Electrochemical process that forms a durable, corrosion-resistant oxide layer.

ALUMINUM · TITANIUM
Powder Coating

Dry finishing process using powdered paint for a durable, colorful finish.

METALS · SOME PLASTICS
Bead Blasting

Creates a uniform matte surface and removes tool marks.

METALS · PLASTICS
Electropolishing

Electrochemical process that smoothens and polishes metal surfaces to a high-gloss finish.

STAINLESS STEEL · COPPER · ALUMINUM
Heat Treatment

Alters physical properties to achieve desired hardness, ductility, or stress relief.

METALS
Black Oxide

Chemical conversion coating that creates a black surface for corrosion resistance.

STEEL · IRON · STAINLESS STEEL
Passivation

Chemical treatment to remove free iron and enhance corrosion resistance of stainless steel.
