Latest Patents

One of Rong-Jau Liaw's latest patents is focused on integrally formed stamped sheet-metal blades that feature a 3D structure. This innovation is designed for use in the impellers or diffusers of centrifugal pumps or blowers. The patent describes a method that includes at least two integral forming blade or vane members. Each member is equipped with a plurality of relatively short 3D blades or vanes that extend radially outward, along with an engaging edge of a selected shape. The design allows for two or more blade or vane members to be positioned and stacked together by mating the engaging edges, which can then be spot welded to create a complete impeller or diffuser assembly. This method not only reduces the number of stamping molds and jigs required for production but also lowers production costs. Additionally, the positioning and assembly of the blades and vanes are simplified, making the manufacturing process more efficient.
