| Abstract: | According to the Hele-Shaw fluid model, a numerical simulation of a pipe for the effects of processing parameters in filling stage of water-assisted injection molding. The effects of the processing parameters on the water penetration length and water thickness fraction were investigated through single factor experiments. According to the results, the short shot size was considered as the principal parameter affecting the water penetration length, the melt temperature,mold temperature,water temperature,water pressure have no clearly effect on the water penetration length and water thickness fraction. |
