Abstract：In this paper,in connection with the specific issues exist in the production process of Car door-handles,using numerical simulation technique orthogonal-experiment design and neural network theories to optimizate  the process parameters of injection-molding of molding-parts,obtained more accurater optimal process parameters，and proposed a new method which forecast the length and position of weld-lines . There was a better effect in controlling weld-lines of Car door-handles by using new theory and new method.
Keywords:Car door-handles,Artificial neural network, Weld-lines, Process parameters optimization,Matlab
