The CAD software made for the four developing systems of blower model choosing and designing system, ventilating fan designing system, blower and ventiting fan's specialized motor developing system is the biggest support of Dedong's mass-production..the motor made by Dedong is exclusively used in Dongma fans and this guarantees the high-quality of our products.

R&D center pushes the first stride in the industry to deploy CAD system and now can conduct 3-dimention analog of wind wheel as well as analog assembly and CAPP system. the pneumatic auto-inspection analysis system designed according to the international standard have realized the computerization from test to analysis.

In recent years, the Dedong technical centre developed a series of new products, try to reach the world class and win the prize from the state, province or the city. The R&D center heads on toward the energy-saving, high-efficient, environment-friendly and low-noise fan, and enhance the cooperation with foreign company.. The integration will boost the transform of research result to productivity and realize the sustainable development strategy of product echelon: production, storage and development.
