Relying on research institutions such as Shanghai Jiao Tong University and Tongji University in Shanghai, the company has professional technicians with many years of experience in fan and air-cooled products. The company uses design software platforms such as PDM and CAD to optimize the smooth design of fan blade profiles, in order to meet the product requirements of low noise, high efficiency and energy conservation. The company is currently establishing a provincial-level technology center to lay a strong foundation for its technological development.

After years of capital accumulation, the company is equipped with complete production tools and facilities, as well as comprehensive testing methods. It possesses advanced processing equipment such as shearing, rolling, bending, and hub molding, as well as dynamic and static balancing equipment (as per the "Main Production Tools" and "Testing Equipment List").
