Aluminum Die-Cast Motor Mounting Flange

Internal splines within the central bore define the torque transmission interface of this cylindrical housing, commonly utilized as an end cover or mounting bracket for micro gear motors and servo actuators. The component features a domed upper cap with a rectangular cutout, likely serving as an access point for drive shaft coupling or manual override mechanisms, while the lateral flange extends outward with through-holes to secure the assembly to equipment frames.

Manufacturing this part requires strict control over the concentricity between the internal spline profile and the external mounting datum to ensure smooth rotational alignment and prevent mechanical binding during operation. The transition from the cast body to the machined sealing surfaces demands precise CNC secondary processing to maintain flatness and positional accuracy, avoiding leakage paths or assembly stress in high-vibration environments.

Our Ningbo facility supports the full production cycle, leveraging Toshiba and Ube cold chamber die casting machines for high-density aluminum alloy formation, followed by precision CNC machining centers for critical feature refinement. Quality assurance processes include CMM verification for geometric tolerances and dimensional stability checks, adhering to ISO 9001 standards. Please provide detailed CAD drawings specifying spline parameters, bore tolerances, and surface finish requirements to initiate a DFM review and receive an accurate quotation.
