Jiangsu Sunray Technology Co., Ltd., founded in 2006, is headquartered in Nanjing, Jiangsu Province. Specializing in the turbomachinery field, the company is committed to providing comprehensive solutions for high-end dynamic sealing products, covering R&D and design, manufacturing, inspection and testing, as well as installation and commissioning.
With brush seal technology as its core, the company consistently maintains a domestic leading and internationally synchronized level of expertise.It is the only enterprise in China to have achieved full-chain independent capabilities in brush seal technology. The company has obtained management system certifications including ISO9001, ISO14001, and ISO45001. It has been honored as a "National Specialized and Sophisticated Enterprise that Refine Features and Innovate" and a "National High-tech Enterprise", holding over 100 independent intellectual property rights.
Domestically, Sunray Tech's customer base covers the three major OEMs, the top five power generation groups, regional power generation groups, AECC, and light-duty gas turbine manufacturers. The company provides brush seal solutions for domestically produced steam turbines, gas turbines, and aero-engines. Leveraging over two decades of continuous innovation in the brush seal field, Sunray Tech has built a comprehensive independent R&D platform and a modern sealing industry base, accumulating profound technical strength. It has repeatedly participated in major national projects, providing critical sealing technology support for China's high-end equipment manufacturing industry.
While deeply cultivating the domestic market, Sunray Tech actively expands its overseas business and has become the exclusive domestic brush seal supplier for global energy industry leaders such as GE Vernova, Siemens Energy, and Mitsubishi.
Corporate culture

Turbomachinery dynamic sealing pioneer. Advancing chinese manufacturing,empowering global energy.
INDUSTRY COOPERATION
Sunray Tech has established long-term in-depth R&D collaborations with multiple universities,including Tsinghua University, Southeast University, Nanjing University of Aeronautics and Astronautics, Shenyang Aerospace University, Guangzhou University, Naniing University of Engineering.and Tianjin University of Science & Technology, as well as with relevant domestic research institutes.
The research outcomes have been successfully applied to high-performance and high-reliability dynamic sealing products for domestically produced core power equipment, achieving independent breakthroughs in key technologies in this field. This has not only strongly facilitated a fundamental shift in China’s high-end equipment core components from import dependence to self-sufficiency and controllability, but also provided critical theoretical support and engineering validation for the technological advancement and development of brush seals.
The company has established a Dynamic Sealing Research Center and an Academician Workstation in collaboration with the team of Professor Wang Yuming, a leading authority in China’s fluid sealing engineering field, an academician of the Chinese Academy of Engineering, and a professor at Tsinghua University. The main research content includes: optimization of brush seal service life and reliability, brush seal performance testing equipment, and dynamic characteristics of brush bristle bundles.
Collaborative Research with Southeast University School of Materials Science on Enhancement of Brush Wire Processing Techniques and Performance Improvement.
Collaborative Research with Shenyang Aerospace University on Brush Seals:Mechanical Properties、Fluid-Structure Interaction、Leakage Characteristics、Wear Characteristics、Structural Characteristics.
