| Abstract: | The plastic part of chair with long legs has the defects of low strength, poor surface quality and filling difficulty.
The CAE technology was applied to make optimization of gas injection system and apply orthogonal design to adjust the
injection parameter to get the best gas injection design and injection parameter. The results of the mold manufacture show
that the gas nozzle opening in the necessary position helps the gas injection. The injection parameters that effect the gas
injection is following, the melt filled volume > gas pressure > gas delay time > melt injection temperature. |

| Keywords: | injection mold gas assisted injection molding ( GAIM) optimization of gas runner system orthogonal |
