The research aimed atreducing the consumption of the PP material of the car’s rear bumper was conducted by analyzing the factors that affect the cost of injection molding for the car’s rear bumper. A group of verification tests for physical property were carried out. The results prove that the cost of injection molding could be effectively reduced by enhancing the regeneration rate of the PP material. Based on the results of the research and testing,concrete measures were put forward,such as raising the crushing capability of the grinder and adding exhausting trough to the injection mould,etc. The results show that these measures can guide the production to achieve the purpose of reducing the cost of injection molding for the rear bumper.
