Surface Finishing Services for Machined Parts

We offer a complete range of surface finishing solutions for machined components. Whether you need corrosion protection, wear resistance, improved aesthetics, or functional marking – we have the right process for your material and application.

Aluminum Anodizing

An electro-chemical process that converts the aluminum surface into a durable, corrosion-resistant oxide layer.

Available types：

- Clear (natural) anodizing  

- Hard anodizing (increased wear resistance)  

- Color anodizing (black, red, blue, gold, etc.)

Black Oxide  (Steel / Iron)  

A chemical conversion coating that produces a black, matte finish on ferrous metals (steel, cast iron).

Benefits：

-Mild corrosion resistance (improved with oil/wax topcoat)  

-Reduces light reflection – anti-glare  

-No dimensional change – ideal for precision threads and fits  

-Low cost and fast processing  

-Gives a professional, uniform black appearance

 Micro-Arc Oxidation (MAO) for Magnesium Alloys   

A high-voltage plasma electrolytic process that forms a hard, dense, ceramic-like oxide layer on magnesium.

Benefit：

-Extremely hard surface (up to 1500–2000 HV)  

-Superior wear and corrosion resistance (far better than anodizing or painting for Mg)  

-Excellent thermal stability and electrical insulation  

-Environmentally friendly – no heavy metals or strong acids  

-Strong adhesion – no peeling or flaking

Painting

Application of liquid paint via spray gun or automated system, followed by curing (air dry or oven bake).

Available types：

- Solid colors (custom RAL/Pantone)  

- Textured finishes  

- High-gloss or matte  

- Anti-static / conductive paint (for electronics shielding)  

- High-temperature resistant paint

Benefits：

-Wide color and finish selection  

-Good corrosion protection (combined with primer)  

-Can fill minor surface imperfections  

-Suitable for mixed materials (metal, plastic, composite) on same assembly  

-Cost-effective for both prototypes and production

 Laser Marking / Engraving

A high-energy laser beam creates permanent marks by altering surface color or removing a thin layer – without contact or tool wear.

Benefits：

-Permanent, wear-resistant markings  

-No consumables or chemicals – very clean process  

-Extremely fine detail – down to <0.1mm line width  

-No mechanical stress or heat damage to the part  

-High-speed and programmable for variable data

-Additional Finishing Options (Available on Request)

Other surface finishing: Passivation; Electropolishing; Zinc/Nickel Plating; Powder Coating; Alodine / Chromate; Brushing / Polishing ect.

No matter your material or performance requirement, the right surface finish transforms a machined part into a reliable, durable, and professional component. From corrosion protection to permanent marking – we deliver the perfect finish, exactly where it matters.
