Surfaces Finishes

Available Surface Finishes for You Choosing

Part surfacing finishing techniques can either be for functional or aesthetic purposes. Each technique has requirements, such as materials, color, texture, and price. Below are the specifications of the plastic finishing techniques rendered by us.

Name Description Materials Color Texture Price Link
P04 2 S02 as machined
As-machined The standard finish for our parts, the “as machined” finish, has a surface roughness of 3.2 μm (126 μin), which removes sharp edges and deburs parts cleanly. All materials n/a Stain $ /
bead blasting 1

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.

Aluminum, Steel, Stainless Steel, Brass, Copper

anodizing Anodizing Keeping our parts in the long term, our anodizing process resists corrosion and wear. It’s also an ideal surface treatment for painting and priming, and it looks great too. Aluminum

Clear, black, grey, red, blue, gold

Smooth, matte finish


electroplating Electroplating Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.

Aluminum, steel, stainless steel

Gold, silver, nickel, copper, brass

Smooth, glossy finish


polishing Polishing

Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make them shine more less shiny, depending on your requirements.

Smooth, glossy finish


powder coating

Powder Coating

Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm.

CNC machining surface finish Brushing


Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

surface finish painting


Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.

Aluminum, Stainless Steel, Steel

Custom Gloss, semi-gloss, flat, metallic, textured


P04 2 S02 black oxide

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.

Steel, Stainless Steel

Black Smooth, matte



alodine rapiddirect


Chromate conversion coating, known as Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.

P04 2 S02 part marking

Part Marking

Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production.
