Surface Finishing

The cleanliness and surface condition of mechanical components directly determine assembly accuracy, service life, and corrosion- and wear-resistant performance. We specialize in providing one-stop cleaning and surface-treatment services for precision machinery, hydraulic valve bodies, automotive parts, molds, and hardware structural components—ranging from degreasing, derusting, and oxide removal to functional surface modification. Our processes are fully standardized throughout the entire workflow, ensuring a stable and reliable substrate for subsequent assembly, painting, electroplating, and welding.

• Core Cleaning Process

Precision cleaning: ultrasonic cleaning and magnetic abrasive finishing for thorough removal of oil, metal chips, polishing compounds, and cutting fluids, while maintaining both cleanliness and part accuracy to meet the cleaning requirements of complex-shaped components.

Deep Cleaning: Multi-stage countercurrent rinsing + final ultrapure water rinse + hot-air/vacuum drying—ensuring no residue, no water spots, and no secondary rust, thereby establishing a pristine surface preparation foundation for subsequent surface treatments.

Applicable scenarios: Blind holes, deep grooves, threaded features, and complex cavities can all be thoroughly cleaned, meeting micrometer-level cleanliness requirements and supporting comprehensive applications in ultrasonic cleaning and magnetic abrasive finishing.

• Mainstream surface treatment processes

Anodizing: Suitable for materials such as aluminum alloys, this process forms a dense oxide film on the surface, enhancing corrosion resistance, wear resistance, and electrical insulation. It can also be combined with coloring to achieve both protective performance and aesthetic appeal.

Electrocoating: The paint film is uniformly adsorbed onto the workpiece surface, exhibiting strong adhesion, high edge and corner coverage, and excellent salt-spray and impact resistance, making it ideal for parts with stringent requirements for corrosion protection and aesthetic consistency.

Powder Coating: Electrostatic powder spraying delivers a thick, full-bodied coating that is wear- and scratch-resistant, environmentally friendly, and solvent-free—making it ideal for long-lasting protection and decorative finishing of various structural components.

Galvanizing, nickel plating, and chrome plating: Galvanizing prioritizes cost-effective rust prevention and is suitable for a wide range of applications; nickel plating delivers a bright, smooth surface that offers both wear resistance, corrosion protection, and aesthetic appeal; chrome plating boasts high hardness and exceptional surface finish, significantly extending component service life and elevating product quality.
