| Abstract: | The PP samples were molded by novel hydraulic vibration injection molding machine.The effects of vibration amplitude and frequency on physical and mechanical properties of PP and power consumption in the plasticizing process were studied.The results show that in the case of imposing vibration under otherwise identical conditions,the tensile strength of PP sample increases by 9.8%,the impact strength increases by 13.8%,the density increases by 0.3%,while the power consumption of the injection molding machine decreases by 6.6%. |
