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.

Imge	Name	Description	Materials	Color	Texture	Price	Link
	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	$	-
	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	$$	-
	Electroplating	Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.	Aluminum, steel, stainless steel	Gold, silver, nickel, copper, brass	Smooth, glossy finish	$$$	-
	Polishing	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	$$$$	-
	Powder Coating	Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm.	All metal materials	Custom	Glossy	$$$	-
	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	$$	-
	Painting	Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.	Aluminum, Stainless Steel, Steel	Custom	Gloss, semi-gloss, flat, metallic, textured	$$$	-
	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	$$	-

See What Our Customers Say About Us

A customer’s words have a more substantial impact than a company’s claims – and see what our satisfied customers have said regarding how we fulfilled their requirements.

The demanding requirement of the automotive industry requires strict adherence to high tolerance standards. cncjsd understands all of these requirements and has provided top-notch polishing services to us for the past decade. These products can withstand various environmental conditions and stay durable for a very long time.

Hi Henry, on behalf of our company, I want to acknowledge the superb quality work we continuously get from cncjsd. The chrome plating quality we got from your company far exceeds our expectations compared to other companies we worked with in the past. We will surely come back for more projects.

I contacted cncjsd for our anodizing needs, and they were confident they could provide the best solution. From the ordering process, it was clear that this company was different from any other metal finishing companies we had ever used. Although the product was in large volume, cncjsd completed the finishing perfectly within a short time. Thanks for your service!
