Custom CNC Machined Aluminum Alloy Heat Dissipation Housing

This custom aluminum heat dissipation housing is processed by composite CNC turning and milling. It features an integrated cylindrical structure with top flange mounting surface, inner cavity, side through holes and vertical cooling fins on the outer wall. The dense array of cooling ribs greatly expands the heat exchange area, achieving excellent heat dissipation performance.
All features including flange bolt holes, inner step cavity, side interface holes and external heat sink ribs are completed with precision machining. We strictly control the perpendicularity, concentricity, flatness and hole position tolerance. One-piece forming avoids heat transfer barriers caused by assembly joints, which is the core advantage for thermal management.
The main material is 6061 aluminum alloy, which has outstanding thermal conductivity and lightweight characteristics. The surface adopts dark hard anodizing treatment, improving surface hardness, wear resistance and corrosion resistance. Sandblasting, ordinary anodizing and other surface finishes are also available on request.
This finned aluminum housing is widely used for servo motors, vacuum pumps, high-speed spindles, industrial lighting, power modules and new energy equipment. It works as both a structural support shell and a passive heat sink, stabilizing the working temperature of internal components and extending service life.
