In the production of CNC machined aluminum parts, anodizing is a frequently applied surface treatment process that improves corrosion resistance and wear resistance while providing a consistent appearance. However, the anodizing process involves direct contact between the part and the anodizing fixture or rack, which leads to localized marks or interruptions in the anodic coating. These areas, known as contact points or rack marks, are unavoidable due to the need for electrical current conduction during anodizing. Proper selection of these contact points is critical in minimizing visual impact, preserving functionality, and maintaining dimensional accuracy in precision parts.
