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
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 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
