Abstract

Gas assisted injection moulding of a rectangular cross-section tensile test specimen has been modelled using a finite element implementation of the pseudo-concentration method, in which the velocity components and pressure are interpolated as primitive variables. Two-dimensional and three-dimensional modelling formulations are presented and in each case wall thickness predictions are compared with actual measurements taken from specimens obtained from computer monitored gas assisted injection moulding production. Two different boundary conditions were used for the injection of gas into the cavity. Initial mechanical testing is used to compare the apparent elastic modulusof the solid material in gas assisted injection moulding specimens with that in solid polymer specimens.
