Aluminum Die-Cast Transmission Housing

Product Overview This complex aluminum housing is a key component for automotive transmission systems. It demonstrates Sunmy Hardware's capability to manage complex geometries that require both lightweight characteristics and high structural strength. This project highlights our expertise in bridging the gap between raw casting and precision post-machining. Key SpecificationsMaterialAluminum Alloy ADC12ProcessHigh-Pressure Die Casting (HPDC) + CNC MillingWeight2.5 kgMold Cavity1*1Surface TreatmentShot Blasting Manufacturing Process Insight Mold Flow Analysis Before production, we simulate the filling process to optimize gate locations, minimizing porosity and air pockets. High-Pressure Die Casting (HPDC) We use a 400T cold chamber die casting machine with ADC12 aluminum alloy to form the complex shape, including the thin cooling fins. Precision Post-Machining After casting, the part is transferred to a 4-axis CNC machining center. We mill the mating surfaces and bore the bearing holes to H7 tolerance, ensuring perfect assembly alignment. Key Features & Benefits Thermal Management Integrated cooling fins maximize surface area for rapid heat dissipation, critical for protecting internal gears. Weight Reduction Optimized wall thickness reduces overall vehicle weight without compromising durability. Complex Internal Structure Includes cast-in ribs and bosses that would be too costly to produce via machining alone. Surface Treatment Shot blasting removes flash and burrs, providing a uniform matte texture ready for assembly or painting.
