Taking injection molding of automobile connector as the research object, a method of injection molding process parameter optimization was proposed based on signal noise ratio( SNR) and gray correlation analysis. Firstly,the process parameter optimization process was given. On the basis of orthogonal test,the influence degree of each process parameter on the optimization objective was obtained by SNR analysis. By using grey relational analysis, multi-objective optimization was transformed into single-objective optimization problem, and the optimal process combination was obtained. The results show that the warping deformation could decrease 5. 19%. The deformation shrinkage decreases 17. 52%.This method could effectively reduce the defects in the process of injection molding and improve the quality of molding products.
