Surface Finishing Overview

Surface Finishings For Custom CNC Machined Parts

We offer a wide range of surface finishing options for custom CNC machined parts to enhance performance, aesthetics, and durability. Our services include anodizing, plating, polishing, coating, and sandblasting. These finishes provide improved corrosion resistance, smoother surfaces, better wear properties, and enhanced appearance, tailored to your specific requirements.

Aluminum Anodizing

Aluminum anodizing is an electrochemical process that enhances the surface of aluminum parts, providing improved corrosion resistance, wear resistance, and aesthetic finish. This process increases hardness, durability, and offers a range of colors, ideal for both functional and decorative applications.

Classification	Description
Chromic Acid Anodizing	Used for applications requiring excellent corrosion resistance with minimal dimensional change.
Sulfuric Acid Anodizing	Widely used for decorative finishes, corrosion resistance, and moderate wear resistance.
Hard Coat Anodizing	Provides a thick, hard coating for high wear and abrasion resistance in heavy-duty industrial applications.
Organic Acid Anodizing	Used for decorative finishes and low-energy applications where corrosion resistance is still required.
Pore Sealing	Seals the porous anodic layer to enhance corrosion resistance and improve appearance.
Color Anodizing	Imparts decorative colors to aluminum parts while maintaining corrosion resistance.
Micro-Arc Oxidation (MAO)	Creates extremely thick, hard, ceramic-like coatings with superior wear resistance and heat resistance.
Electroless Anodizing	Provides hard coatings without electrical current, ideal for non-conductive or small complex parts.
