Surface Finishing
What Is Surface Finishing
Surface finishing refers to the different processes used to alter the surface of a finished product to give it a unique or desired look and feel. Different technologies are used to improve the appearance, adhesion, solderability, corrosion resistance, hardness, electrical stability, and many other properties of industrial components.
Advantages of Surface Finishing
No matter what manufacturing process you use, high-quality surface finishing services can improve the aesthetics and function of your parts. NOBLE offers various premium metal, composite, and plastic surface finishing services to bring the prototype or part of your dreams to life.

| Picture | Technology | Description |
 | As Machined | Coming out of the machine after machining, our parts are cleaned of any sharp edges and burrs while retaining marks. Without any added material, the part had a surface roughness of 3.2 μm (126 μin). |
 | Band Blasting | Band blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts |
 | Anodizing | To increase surface hardness and dissipate heat, we use anodizing techniques to enhance the look of parts and blend well for painting and priming. |
 | Electroplating | Electroplating reduces 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. |
 | Polishing | Working on metal and hard plastics, our polishing uses highly efficient machinery to get our parts between Ra 0.8~Ra0.1 for a cleaner surface. |
 | Powder coating | We apply a thin layer of protective polymer with the corona discharge phenomenon to give our part a lasting finish that protects from impacts and prevents wearing down. |
 | Brushing | Our brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color. |
 | Painting | Spray droplets can be dispersed uniformly or in fine amounts to cover a wide surface area and bring out greater color to the part. |
 | Black Anodized | Adding layers to metallic surfaces like steel, our black anodized technique improves appearance while maintaining durability. |
 | Alodine | We use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts. |
 | Laser Carving | Helpful in brand recognition or parts organization, we use laser carving that applies various printing methods during full-scale production to quickly embed barcodes, lettering and logos on the parts. |
Our Surface Finishing Specifications
Part surface finishing techniques can improve the aesthetics and function of your parts. Each surface treatment process has requirements, such as material, color, texture, and price. Below are the specifications of the surface treatment technologies offered by NOBLE.[Get Quote]
| pic | Name | Description | Materials | Color | Texture |
 | Anodizing | Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. | Aluminum | Clear, black, grey, red, blue, gold. | Smooth, matte finish |
 | 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 deburr parts cleanly. | All materials | N/A | Stain |
 | Sand Blasting | Sand blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments. | Aluminum, Brass, Copper | N/A | Matte |
 | Powder Coating | Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. | All metal materials | Custom | Gloss or semi-gloss |
 | Electroplating | Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common. | Aluminum, steel, Stainless Steel | Gold, silver, nickel, copper, brass | Smooth, Glossy finish |
 | Polishing | Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection. | All materials | Smooth, glossy finish | 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 Anodized | coating is 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 |
 | Laser Carving | laser carving 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 |

Surface Finishing FAQs
- Q
What is the surface finishing process?
AIn general, surface finishing processes encompass a wide range of industrial processes that remove, add, or alter the material, "finish" or complete the surface of a manufactured product.
- Q
Why is surface finishing important?
ASurface finishing of parts or prototypes will provide the surface smoothness of the parts, increase the anti-wear and anti-fatigue ability, increase or reduce the friction and wear of the matching parts, and improve the anti-corrosion ability and aesthetics of the parts.
- Q
What are surface finishes examples?
ANOBLE lists some common surface finishing:
painting and rolling
spraying.
electroplating.
adhesives.
sandblasting.
heat or pressure bonding.
printing.
NOBEL lists different materials that can use surface finishing:
Material Finishes Papers and boards Printing, waterproof coating, laminating, spot varnish, foil backing, foil or relief embossing, UV varnish Textiles Stain protection, waterproof coatings, mould and mildew protection, printing, dyeing, distressing (making it look old), flameproofing, crease resistance Timber and wood Painting, varnish, wax, stain, preservative, pressure treatment Metals Powder coating, dip coating, galvanising (coating iron or steel with zinc), electroplating (coating with a thin layer by electrolysis), shot blasting (cleaning or etching by firing a stream of high-speed metal beads) Polymers Polish, vinyl decals (sticky backed vinyl cut into decorative shapes), printing Electronics Protective insulation, lacquering, lubrication - Q
What are the factors that may affect my surface finishing?
ASome factors that can affect the quality of the surface finish include cutting-edge geometry, tool wear, built-up edge, and machine tool accuracy.
- Q
How do you paint metal without leaving brush marks?
ANOBLE's engineers generally ensure no brush marks are left when painting the metal, usually removing any loose paint, buffing the metal surface, then applying a suitable oil-based primer, and sanding the metal surface until smooth to ensure your color blends evenly, Use a sprayer to paint the metal surface so that the paint on the metal part does not leave brush marks.
