Design:
The technical R&D center of Cowinns makes use of the most advanced computer technology to enhance the quality of existing products and develop new valves. During the new product design period ,we introduce Auto CAD and Solidworks and adopt the advanced FEA technology to verify it the design of new products are feasible before they are put into batch production, so that their design and development time is greatly short and the safety of final products and their optimal cost structure are ensured.
