Latest Patents

One of Li Zhan's latest patents is a "Method for weaving three-dimensional preform having gradient structure." This innovative method involves several steps, including decomposing and determining performance requirements for different functional locations of parts. It also includes selecting guide sleeves and fibers for each functional location, designing parameters, and implementing a smooth transition in the transition area. The method generates a fiber iterative instruction for layer-by-layer weaving, ultimately producing a three-dimensional preform with a gradient structure.

Another notable patent is the "Digital processing method and device of large or medium-size sand mold." This method inverts a three-dimensional CAD model of a mold into numeric controlling code. It involves placing a prepared sand blank on a hollow grid-shaped processing platform for digital milling. The process efficiently removes waste sand using high-pressure gas, which is blown out from a nozzle near the cutter, directing the waste into a collecting device below the processing platform. This innovation reduces the number of processing steps required.
