Gearbox Housing

Premium Gearbox Housings Engineered for Durability & Precision

When reliability matters, your machinery deserves a gearbox housing built to last. At rongbaocasting.com, we specialize in high-performance transmission casings engineered for demanding automotive, industrial, and renewable energy applications. Our ISO-certified manufacturing process combines the strength of A380 aluminum alloys with the precision of sand casting and advanced CNC machining to ensure consistent quality and durability. These housings are built to perform under extreme operating conditions, including temperatures ranging from -40°C to 300°C and heavy mechanical loads, making them ideal for both conventional and next-generation powertrain systems.

Why Choose Our Gearbox Housing Solutions?

✅ Material Versatility: Select from aluminum alloys (like A380), ductile iron, or custom composites to balance weight, strength, and corrosion resistance.

✅ ±0.01mm Tolerance: Achieve perfect alignment with CNC-machined surfaces and integrated cooling channels.

✅ Rapid Prototyping: Go from CAD designs to functional prototypes in 15 days.

✅ Global Compliance: Meets IATF 16949, AS9100, and REACH/ROHS standards.​​​​​​​
