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.

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.[Get Quote]

图片3As MachinedComing 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).
图片4Band BlastingBand blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts
图片5AnodizingTo increase surface hardness and dissipate heat, we use anodizing techniques to enhance the look of parts and blend well for painting and priming.
图片6ElectroplatingElectroplating 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.
图片7PolishingWorking 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.
图片8Powder coatingWe 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.
图片9BrushingOur brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color.
图片10PaintingSpray droplets can be dispersed uniformly or in fine amounts to cover a wide surface area and bring out greater color to the part.
图片11Black AnodizedAdding layers to metallic surfaces like steel, our black anodized technique improves appearance while maintaining durability.
图片12AlodineWe use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts.
图片13Laser CarvingHelpful 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]

图片16Sand BlastingSand 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, CopperN/AMatte
图片17Powder CoatingPowder 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 materialsCustomGloss or semi-gloss
图片18ElectroplatingElectroplating 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 SteelGold, silver, nickel, copper, brassSmooth, Glossy finish

Surface Finishing FAQs

  • Q

    What is the surface finishing process?


    In 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?


    Surface 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?


    NOBLE lists some common surface finishing:

    painting and rolling





    heat or pressure bonding.


    NOBEL lists different materials that can use surface finishing:

    Papers and boardsPrinting, waterproof coating, laminating, spot varnish, foil backing, foil or relief embossing, UV varnish
    TextilesStain protection, waterproof coatings, mould and mildew protection, printing, dyeing, distressing (making it look old), flameproofing, crease resistance
    Timber and woodPainting, varnish, wax, stain, preservative, pressure treatment
    MetalsPowder 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)
    PolymersPolish, vinyl decals (sticky backed vinyl cut into decorative shapes), printing
    ElectronicsProtective insulation, lacquering, lubrication
  • Q

    What are the factors that may affect my surface finishing?


    Some 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?


    NOBLE'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.
