CNC Machining and Anodizing Type II and III

In the competitive landscape of custom part manufacturing, achieving the perfect balance of dimensional precision and superior surface properties is paramount. This is where the synergy between CNC machining and Type II & III anodizing becomes a gamechanger, offering a comprehensive solution for highperformance components across aerospace, medical, and consumer electronics industries.

CNC machining stands as the foundation of this process. Utilizing computercontrolled mills, lathes, and multiaxis systems, we transform raw materials like aluminum, titanium, and stainless steel into complex, hightolerance parts. The inherent accuracy of CNC machining ensures that every feature, from critical threads to tightfitting interfaces, is produced with impeccable repeatability. However, even the most precisely machined aluminum part remains vulnerable to wear, corrosion, and cosmetic degradation. This is where anodizing provides the critical finishing touch.

Anodizing is an electrochemical process that thickens and strengthens the part's natural oxide layer. We specialize in both Type II and Type III, each serving distinct purposes:

Type II Anodizing (Chromic or Sulfuric Acid): This is the most common decorative and protective finish. It creates a corrosionresistant surface that is excellent for dyeing in a vast spectrum of colors. Beyond aesthetics, Type II provides a hard, durable coating that protects parts from wear and is ideal for consumerfacing products, internal mechanisms, and applications in mildly corrosive environments.

Type III Anodizing (Hard Anodizing): For components subjected to extreme conditions, Type III is the superior choice. This process creates a much thicker, denser, and harder coating than Type II. The resulting surface is exceptionally resistant to abrasion and corrosion, possesses high dielectric strength, and improves the part's lubricity. It is the goto finish for military gear, aerospace components, hydraulic systems, and any part requiring maximum durability.
