Optimization analysis of the injection molding process based on Orthogonal test method and Uniform design

摘要

A car battery bracket was taken as the research object and the warp deformation of plastic products was as the quality evaluation index, through the range analysis of orthogonal test method, the influence degree of the warp deformation from the melt temperature, mold temperature, injection time, packing pressure and dwell time was determined, the preliminary optimization of process parameters combination was obtained. Further uniform design was applied for local optimization by taking the preliminary optimized parameters as the basis, the optimal process parameters combination was obtained and further verified by simulation.
