Our Surface Finishes

Here is a list of optional super surface finishing. For custom high surface finish such as electroplating or polishing, please contact sales@zdcpu.com.

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
