Abstract: The effect of delayed-time on gas fingering was investigated.Combining the numerical simulation with the experiment, the change of the delayed-time was used to measure the change of the gas fingering behaviors. The experiment results are in agreement with that obtained by the numerical simulation.Results show that gas fingering behavior decreases as delayed-time increases.

Key words: gas-assisted injection molding, delayed-time, gas fingering
