Product Overview
The Automotive Differential Housing forms the structural enclosure for the differential mechanism within a vehicle's drivetrain. It provides space and mounting support for internal gears, bearings, and related drive components while helping maintain their specified positions during operation. The housing must accommodate the required internal clearances, bearing locations, fastening points, and mating surfaces. Its structural rigidity and dimensional accuracy are important to gear alignment, assembly consistency, and the reliable operation of the drivetrain.
Sangroove (Jiangsu) Machinery Co., Ltd. manufactures automotive differential housing castings for different vehicle and drive axle applications. Production can be developed around customer drawings, selected material grades, component weight, and machining requirements. Listed material options include QT500, QT600, and QT700 ductile iron, as well as ZG310-570 and ZG355-500 cast steel grades. The final material should be selected according to the component design and the mechanical requirements specified for the application.
Depending on housing geometry and production needs, green sand casting or shell mold casting may be used to form the main body. Subsequent operations can include stress-relief heat treatment when specified, CNC machining of bearing seats and mating interfaces, and surface protection. Inspection requirements may cover chemical composition, hardness, metallographic structure, critical dimensions, and UT/MT testing where applicable. Customers can provide 2D drawings or 3D CAD files to define the housing structure, machining allowances, sealing interfaces, and acceptance criteria before production.
Manufacturing Process
Housing Drawing Assessment: Review the internal structure, bearing locations, fastening points, and mating surfaces.
Tooling and Pattern Development: Prepare casting tooling according to the approved housing geometry.
Casting Process Selection: Use green sand or shell mold casting based on component design and production requirements.
Melt Chemistry Control: Check metal composition against the specified material grade.
Stress-Relief Heat Treatment: Apply when required by the approved manufacturing specification.
CNC Machining: Process bearing seats, mounting faces, joint surfaces, and other drawing-defined features.
Surface Protection: Provide E-coating, anti-rust coating, or phosphating according to project requirements.
Casting and Machining Inspection: Verify applicable material properties and critical dimensions; conduct UT/MT testing when specified in the inspection plan.
