Front and Rear MainReducer Housing and Differential Housing Premium Casting Services Product

Advanced Material for Superior Performance

The extreme stresses and torsional loads experienced by reducer and differential housings demand a material with exceptional mechanical properties. We primarily utilize high-grade Ductile Iron (e.g., GGG50/500-7) for these applications due to its optimal combination of:

• High Tensile Strength and Toughness: Withstands high input torque, shock loads, and internal gear forces without cracking or deforming.

• Excellent Fatigue Resistance: Endures the constant cyclic stresses from rotating components, preventing fatigue failure over the vehicle's lifetime.

• Good Damping Capacity: Effectively absorbs vibrations and noise generated by the gears, contributing to a quieter and smoother operation.

• Superior Machinability: Allows for precision machining of critical features, ensuring perfect bearing seat alignment and housing bore concentricity.

Precision-Oriented Premium Casting Process

Our "premium" designation is earned through a meticulous, controlled manufacturing process tailored for these complex components:

1. Advanced Mold Making: We use high-precision shell molding or furan resin sand casting techniques. These processes create rigid molds that produce castings with excellent surface finish, dimensional accuracy, and a dense, defect-free microstructure—essential for housing integrity.

2. Controlled Pouring and Solidification: The molten ductile iron is poured under controlled conditions to ensure optimal filling and solidification, preventing internal defects like shrinkage cavities.

3. Heat Treatment: All housings undergo a stress-relieving heat treatment to ensure dimensional stability and relieve internal casting stresses, which is critical for maintaining long-term alignment under load.

4. Comprehensive CNC Machining: This is a critical step. The raw casting is transformed into a precision component using advanced CNC machining centers. We machine the mounting flanges, bearing bores, seal surfaces, and cover interfaces to exacting tolerances. This guarantees perfect gear alignment, prevents oil leaks, and ensures seamless integration with the axle assembly.
