DONG Binbin, SHEN Changyu, LI Qian, et al. Effect of process parameters on hollow ratio of pipe part by gas-assisted injection molding[J]. CIESC Journal, 2007, (6): 1587-1591.DOI:
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.
