Surface Finishing Options
Get your metal and plastic parts a high quality and aesthetic surface finish. Bead blasting, anodizing, powder coated, etc in as fast as 5 days.
Available surface finishes
Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing, please contact Gben@cncchinese.com
As-machined
Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.

Bead blasting
Bead blasting is the process of powerfully propelling, generally with high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities.

Anodizing
Anodizing is an electrolytic passivation process that grows the natural oxide layer on aluminum parts for protection from wear and corrosion, as well as for cosmetic effects.

Electroplating
Electroplating is a process that uses an electric current to reduce metal cations in the electrolyte solution, producing a metallic coating on a metal surface. This process can be used for purposes of corrosion and wear resistance, as well as for decorative purposes.

Powder coating
Powder coating is a dry coating process used to apply free-flowing, dry color powder to a metal substrate. Unlike normal wet painting that contains solvent, powder coating is applied as a dry powder by electrostatic attraction, then melted and fused into an even coating with heat.

Black oxide
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance.

Alodine
Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivate and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.
