Plastic injection molding products are increasing gradually in automobile components parts. Among them, large injection melded parts such a automobile bumper fascia and instrument panel are known as not only expensive but also time consuming from design to mass production. Design and manufacture of the large injection molded parts have to repeat various processing modification of mold and tryout. It could simulate design factor simulation on several conditions at mold design process by the development of CAE technology. It has effects on reduce mold making time and cost. But, these studies attach importance to small injection mold. <br/> This paper presents CAE simulation to injection molding of the large molded parts. Optimization of molding if discusses on type and location of runner and gates. And the simulation results are compared with fill time, weld line and injection pressure in actual process and parts .
