Patent number: 11860590Abstract: The present invention discloses a model-free optimization method of process parameters of injection molding to solve the problems of frequent tests required and performing adaptive adjustment on different parameters in the existing optimization method. The method need not build a surrogate model between a product quality index and a process parameter to render the process parameter to converge nearby the optimal solution by an on-line iteration method. The present invention calculates the gradient direction of a current point by an iterative gradient estimation method, and uses adaptive moment estimation algorithm to allocate an adaptive step for each parameter. The method can significantly reduce the cost and time required in the process parameter, which greatly helps improving the optimization efficiency of process parameters of injection molding.Type: GrantFiled: May 24, 2021Date of Patent: January 2, 2024Assignee: ZHEJIANG UNIVERSITYInventors: Peng Zhao, Zhengyang Dong, Kaipeng Ji, Hongwei Zhou, Jianguo Zheng, Tingyu Wang, Jianzhong Fu
