Abstract:

The effects of processing parameters of gas-assisted injection molding(GAIM) on the hollow ratio of the pipe parts was studied.The process parameters, such as melt temperature, mold temperature, gas delay time, melt filled volume and gas pressure, were investigated by means of computer aided engieering(CAE) simulation.Numerical examples showed that the hollow ratio was sensitive to melt filled volume and gas pressure.Melt temperature and mold temperature had no influence on the hollow ratio when the temperature reached a specific range.Gas delay time did not have obvious influence on the hollow ratio.
