Our Surface Finishing Services
NOBLE has more than ten years of experience in surface treatment and excellent engineers, who are proficient in surface treatment of plastics, metals, and composite materials, and can turn your dream prototype or parts into reality.
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~Ra 0.1 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.
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.
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.
Materials: Aluminum
Color: Clear, black, grey, red, blue, gold.
Texture: 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.
Materials: All materials
Color: N/A
Texture: 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.
Materials: Aluminum, Brass, Copper
Color: N/A
Texture: Matte
Electroplating
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.
Materials: All metal materials
Color: Custom
Texture: 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.
Materials: Aluminum, steel, Stainless Steel
Color: Gold, silver, nickel, copper, brass
Texture: 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.
Materials: All materials
Color: Smooth, glossy finish
Texture: 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.
Materials: ABS, Aluminum, Brass, Stainless Steel, Steel
Color: N/A
Texture: 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.
Materials: Aluminum, Stainless Steel, Steel
Color: Custom
Texture: 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.
Materials: Steel, Stainless Steel
Color: Black
Texture: 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.
Materials: Aluminum
Color: Clear, Gold
Texture: 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.
Materials: All materials
Color: Custom
Texture: N/A

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.
