Nodular Differential Housing Castings Factory Offering Quality Casting Services

As a specialized nodular differential housing castings factory, we deliver precision-engineered casting solutions for automotive and heavy-duty applications. Our differential housing castings provide the perfect balance of strength, durability, and weight optimization for demanding operating conditions.

Material Excellence
Our castings utilize high-grade nodular iron (ductile iron) EN-GJS-400-18, EN-GJS-500-7, and EN-GJS-600-3, characterized by:

• Superior tensile strength (400-600 MPa)

• Excellent elongation properties (18-3%)

• Outstanding impact resistance

• Enhanced fatigue strength
  The unique spherical graphite structure within the ferritic or pearlitic matrix gives nodular iron its exceptional mechanical properties, combining the durability of cast iron with the flexibility of steel.

Advanced Production Technology
We employ state-of-the-art manufacturing processes:

• Automated molding lines using green sand and resin sand technologies

• Precision pattern making with CNC machining

• Controlled melting in medium frequency induction furnaces

• Inoculation and magnesium treatment for perfect nodularization

• Advanced heat treatment processes (annealing, normalizing, quenching)

Performance Advantages
Our nodular differential housing castings offer:

• Excellent vibration damping capacity

• Superior wear resistance for extended service life

• High strength-to-weight ratio

• Good machinability for secondary processing

• Reliable performance under extreme torque conditions

Quality Assurance
Every casting undergoes rigorous quality control:

• Spectrochemical analysis for material verification
