Surface Finishing Services
The Importance of Surface Finishing
Surface finishing is more than an aesthetic enhancement. It's a critical step in manufacturing that affects metal parts' performance, durability, and reliability. Whether we’re machining aluminum, stainless steel, or other alloys, the surface plays a vital role in determining how parts function in real-world conditions. Proper surface finishing can increase corrosion resistance, reduce wear, and improve surface roughness. It also eliminates machining marks that could interfere with component performance or fit. A refined surface finish is often a requirement for precision parts, not just a preference.
Key Surface Finishing Processes
Our shop offers a wide range of surface finishing services designed to meet the exact needs of your project. These include polishing, anodizing, bead blasting, nitriding, plating, and powder coating. Anodizing forms a controlled oxide layer on aluminum parts, improving corrosion resistance and wear protection. Powder coating adds a durable layer of color and protection to metal components.
Nickel plating enhances corrosion resistance and provides a bright, uniform appearance. Bead blasting gives metal parts a smooth, matte surface while removing minor imperfections. Each process is carefully selected to meet the specifications and performance goals of the part.

Industry Applications
We serve a wide variety of industries that demand high-performance, precision-finished parts. Aerospace companies rely on anodized aluminum and polished stainless steel components that resist corrosion and maintain tight tolerances. Automotive and transportation sectors benefit from powder-coated and nickel-plated components that withstand wear and exposure to the elements. We apply surface finishes in medical and electronics applications that meet strict regulatory and cleanliness standards.
Every industry has unique requirements, but they all share one thing: They depend on precision and consistency. Our surface finishing services are engineered to meet those expectations, every time.
What Are the Different Types of Surface Finishes?
Different manufacturing needs call for different surface finishes. Here are a few of the most common types we offer:
- Polished finish: Produces a smooth, reflective surface often used for cosmetic or low-friction applications
- Anodized finish: Adds an oxide layer to aluminum parts, increasing hardness and corrosion resistance
- Bead blasted finish: Provides a uniform matte texture and removes minor surface defects
- Powder coated finish: Adds a protective and decorative layer of polymer resin
- Nickel plated finish: Enhances corrosion resistance and provides a uniform metallic surface.
- Nitride Coating: This process enhances the metal's durability, corrosion resistance, and lubricity.
Each surface finish can be tailored based on material, function, and industry standards.
We ensure consistent results across all surface finishes, from small batches to large production runs. Contact the Wilco Precision team to find a partner you trust.
