Our Surface Finishing Specifications

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.

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	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	n/a	Matte	$	Learn More>>
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	$$	Learn More>>
Electroplating	Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.	Aluminum, steel, stainless steel	Gold, silver, nickel, copper, brass	Smooth, glossy finish	$$$	Learn More>>
Polishing	Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements.	All materials	n/a	Smooth, glossy finish	$$$$	Learn More>>
Powder Coating	Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm.	All metal materials	Custom	Glossy	$$$	Learn More>>
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.	ABS, Aluminum, Brass, Stainless Steel, Steel	n/a	Satin	$$	Learn More>>
Painting	Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.	Aluminum, Stainless Steel, Steel	Custom	Gloss, semi-gloss, flat, metallic, textured	$$$	Learn More>>
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	$$$
Alodine	Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.	Aluminum	Clear, Gold	Same as before	$$$
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.	All materials	Custom	n/a	$$
