At GD Prototyping, we specialize in producing CNC Machined Anodized Aluminum parts that merge precision engineering with high-performance surface finishing. CNC machining allows us to create complex, tight-tolerance components from aluminum alloys, ensuring exceptional accuracy and repeatability. To further enhance these parts, we apply anodizing, which strengthens the surface, improves wear resistance, and delivers a refined aesthetic.
CNC machining provides the flexibility to manufacture everything from intricate prototypes to large-scale production runs. By integrating anodizing, the machined parts gain an added layer of protection against corrosion, scratches, and fading, making them suitable for industries that require both functionality and appearance.
Our anodized aluminum parts can be finished in various colors, including black, silver, gold, red, and blue, giving customers the option to align with branding or product design. With tolerances up to ±0.005 mm and surface roughness that meets industry standards, every part reflects superior craftsmanship.
Whether you need functional prototypes, small-batch runs, or full-scale production, GD Prototyping delivers CNC machined anodized aluminum solutions that balance strength, precision, and design excellence.
