Our Surface Finishes

 

Here is a list of optional super surface finishing. For custom high surface finish such as electroplating or polishing, please contact [email protected].

 

As Machined

For as machined all sharp edges are removed and parts are deburred. Tool marks are visible.

 

Smoothing

A finishing CNC machining operation can be applied to the part to reduce its surface roughness. Machine marks are less evident but still visible.

 

Material compatibility: All plastics and metals

 

Bead Blasting

Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.

 

Material compatibility: All metals

 

Color: Uniform matte of raw material color

 

Powder Coating

Powder coating is a strong, wear-resistant finish that is compatible with all metal materials and can be combined with a bead blasting to create parts with smooth and uniform surfaces and excellent corrosion resistance.

 

Material compatibility: All metals

 

Color: Black or any RAL code or Pantone number.

 

Anodizing Color (Type II)

Type II anodizing is mainly used to produce parts with a uniform, aesthetically pleasing surface and provides good corrosion and limited wear resistance.

 

Material compatibility: Aluminum alloys

 

Color: Black, clear or any RAL code or Pantone number

 

Anodizing Hardcoat (Type III)

Type III anodizing provides excellent corrosion and wear resistance, suitable for functional applications.

 

 

Material compatibility: Aluminum alloys

 

Color: Black or clear

 

Electropolishing

Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness.

 

Material compatibility: All metals

 

Color: Natural metal color

 

Black Oxide

Black Oxide

Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.

 

Material compatibility: Stainless steel and copper alloys

 

Color: Black

 

Chromate Conversion Coating (Alodine/Chemfilm)

Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.

 

Material compatibility: Aluminum and copper alloys

 

Color: Clear or yellow

 

Brushing

Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.

 

Material compatibility: All metals
