Reliable Casting Solutions for New Energy & Power Equipment
New energy and power castings cover wind power, photovoltaic, solar thermal, thermal power, nuclear power, and hydrogen energy. Wind power hydraulic and braking parts face complex alternating loads and low-temperature impact; photovoltaic tracker components require outdoor weather resistance for more than 25 years; nuclear and hydrogen castings require strict material cleanliness, soundness, and long-term reliability; thermal power burner nozzles must work for long periods in high-temperature oxidation environments.
With low-temperature wax silica sol investment casting and integrated machining capabilities, we provide small and medium precision cast steel and stainless steel parts for new energy and power equipment. Key parts undergo 100% NDT to meet long-life design and certification requirements.
High Reliability: Key parts undergo 100% NDT (UT + MT) to meet 20-year wind power and 25-year photovoltaic design life requirements.
Low-Temperature Toughness: Refined low-alloy steel can meet -40°C impact requirements for northern and offshore wind power conditions.
Clean Materials: External refining and heat treatment strictly control harmful elements such as P and S, providing excellent weldability.
Precision Dimensions: CT7 accuracy reduces machining allowance for large components and lowers customer manufacturing cost.
Certification Support: CE, PED, and material traceability documents required by nuclear, wind power, and related industries can be provided.
