Abstract
Based on generalized Hele-Shaw(GHS) model, numerical simulation of
compression-molding flow of sheet molding compound (SMC) in complicated dies is realized by
control volume/finite element method (CV/FEM). Finite element computing and post analysis
programs have been written. The flow fronts of SMC charge during compression molding are
tracked, and the time needed of mold filling in complicated dies is predicted. The results of
simulation are helpful for the placement of SMC charge, the design of mold and the optimization of
technological parameters.
