| Abstract: | In order to study the relationship between the main process parameters and the cell size,the mathematical model of cell growth of microcellular foaming injection process is built.Then numeric simulation is employed as experimental method,and the Taguchi method is used to analyze significance of effect of process parameters on the cell size.At last the process parameters are focused on melt temperature,injection time,mold temperature and pre-filled volume.The significance order from big to small of the effect of each process parameters on cell size is melt temperature,pre-filled volume,injection time,and mold temperature.On the basis of above research,the effect of each process parameter on cell size is further researched.Appropriate reduction of the melt temperature and increase of the pre-filled volume can optimize the cell size effectively,while the effects of injection time and mold temperature on cell size are less significant. |
