We integrate large-scale casting and precision machining capabilities. Our mature heavy-section ductile iron technology ensures consistent quality for ultra-large castings, supporting customized mass production of heavy-tonnage orders.

For wind power: Our independently developed low-temperature high-toughness ductile iron technology for key components and large-scale castings has passed official appraisal, outperforming foreign equivalent products. As of 2025, our maximum hub casting weighs 94 tons.

For nuclear power: We have developed 100-ton ductile iron spent fuel transport containers, certified as China’s First-of-a-Kind Equipment.
