Surface Finishing

Apart from product manufacturing services, Baorun also provides our clients with multiple surface finishing options, to bring a one-stop manufacturing experience. From designing all the way to finish, our service is the best solution to speed up your project.

We got a team dedicated to surface finishing. we provide surface finishing services for all parts in any quantity, and quality is also guaranteed.

Surface Finishing Options

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.

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.

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.

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.

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.

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

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.

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

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.

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.

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.
