A study on gas-assisted injection molding filling simulation based on surface model of a contained circle channel part
چکیده انگلیسی

A practical model of cavity filling in gas-assisted injection molding (GAIM) based on the surface mode has been presented. In this model, according to the flow field at the gas front, gas penetration thickness was educed by solving the theoretical equations governing the behavior of the gas penetration through the matching asymptotic expansion method. In addition, a technology of generating gas channel mesh semi-automatically based on maximum inscribed circle of arbitrary polygon was to proposed. This method combined selecting the path of gas channel manually and calculating the parameters of gas node automatically. Finally, an experiment was employed to verify this proposed model by comparing the results of the experiment with the simulation.
