Surface Finishes

Surface finishing plays a critical role in the performance, durability, and appearance of machined components.
Prime Kun Wu supports a range of surface treatments to meet functional and aesthetic requirements across industries.
Surface finish selection should align with application needs, environmental exposure, and mechanical performance expectations.

Surface Finishing Options for Precision Machined Parts

Why Surface Finishing Matters

Surface treatments can:

Improve corrosion resistance

Increase wear resistance

Enhance surface smoothness

Improve visual appearance

Support downstream assembly or coating processes

Selecting the correct finish ensures parts perform reliably over their intended service life.

Mechanical Finishing Options

Deburring & Edge Finishing

Removes sharp edges and improves handling safety.

Surface Polishing

Improves smoothness and reduces surface roughness.

Brushing / Satin Finish

Provides consistent surface texture and aesthetic appeal.

Bead Blasting

Creates uniform matte surface appearance.

Protective Coatings

Options

Anodizing (Aluminum)
Improves corrosion resistance and surface durability.
Powder Coating
Adds protective and decorative layers.
Plating (Nickel, Zinc, etc.)
Enhances corrosion protection and wear resistance.
Passivation (Stainless Steel)
Improves corrosion resistance by removing surface contaminants.
