Aluminum Die-Cast Motor Mounting Flange With Internal Splines

Provide detailed CAD drawings specifying spline module, pitch diameter tolerances, and flange mounting hole positions to initiate the DFM review for this motor interface component. The part features a central cylindrical hub with internal splines for torque transmission, surrounded by a multi-directional mounting bracket that integrates threaded ports and positioning holes for secure attachment to equipment frames or actuator bodies.

Cold chamber die casting establishes the near-net shape of the aluminum housing, requiring precise control over gate placement to ensure dense material structure around the spline bore and prevent shrinkage defects in the thick-to-thin wall transitions. Subsequent CNC machining focuses on achieving tight concentricity between the internal splines and the external mounting datums, as well as maintaining strict flatness on the mating surfaces to guarantee smooth rotational alignment and prevent mechanical binding during operation.

Production is supported by Toshiba and Ube cold chamber die casting machines alongside high-precision CNC machining centers, enabling consistent output for automotive, robotics, and industrial automation applications. Quality verification utilizes CMMs for critical dimension checks and surface inspection tools to validate finish requirements, ensuring each batch meets the rigorous standards expected for power transmission components in dynamic environments.
