Abstract: The characteristics of gas-assisted injection molding have been investigated, and the mathematical model of the filling simulation is thus established. Aiming at solving the gas penetration interface, which is the key problem in the implementation of the simulation, a detailed calculation model is presented. The simulation results based on this model seem to agree well with the experimental results.

Key words: matching asymptotic expansion method, computer simulation, plastic processing, gas-assisted injection molding
