Warpage is a serious defect for the injection-molded parts.In this work
an approximate optimization method based on the Kriging model was proposed to do warpage optimization.Molflow software was used to analyze the warpage deformation of the injection-molded parts
and mold temperature
melt temperature
injection time and packing pressure were regarded as process parameters.The Kriging model provided the approximate mapping relationship between warpage and the parameters
replacing the warpage analysis of Moldflow in the optimization.Taking the cover of a phone for example
the result of the example showed that the optimization method could decrease effectively warpage deformation.Moreover
the optimization result and influence factors were analyzed in detail.
