CNC Machined Aluminum 4-Prong Flange | Lightweight Transmission Component
September 14, 2026
When your power transmission system demands both low weight and reliable strength, our custom CNC 4-prong aluminum flange delivers the ideal solution.
This four-arm flange is precision milled from solid aluminum billet. The hollow cut-out structure effectively reduces overall weight without compromising mechanical rigidity, perfectly suited for high-speed rotating assemblies. Every mounting hole and central bore is processed under tight tolerance control to guarantee accurate alignment and smooth assembly. Its polished surface treatment brings excellent oxidation resistance, extending service life under continuous operation.
We support full custom machining service. Based on your CAD drawings or samples, we can adjust dimensions, hole layouts and surface finishes, including anodizing, sandblasting or polishing. It is widely used for go-kart, racing equipment, automation machinery and other power transmission projects.
We provide one-stop service covering prototype testing and mass production. Our engineering team reviews your design to optimize manufacturability and cut your production cost.
