Moldflow software is used for Design Optimization of injection mold .we can find a best gate location by using Moldflow .Then ,Comparison and analysis was made between six CAE plastics feeding schemes by applying MPI 5. 0 software and a feasible plan was obtained. With the help of MoldFlow simulating analysis software MPI, injection forming is simulated and analyzed by computer for a kind of injection product, according to the result to analyze melting-joint imprint and bubble chamber, injecting system of mold is optimized and designed, prediction of high quality products is obtained, it proves that CAE technology has strong guidance function to plastic mold design and plastic products forming. It fully reveals the outstanding effect of CAE technology in design of feeding system and development of injection mould. Based on the key technology of plastic injection mold design, the solution of Moldflow/MPI CAE is introduced．The application of Moldflow/MPI in optimizing the design of plastic injection mold is elaborated with an instance of thin wall plastics．The results analyzed by Moldflow/MPI is
