Our Surface Finishes


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

As Machined

As Machined

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

Smoothing

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

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

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)

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)

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

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 (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

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
