Abstract
The influence of melt elasticity on the mold filling behavior in a fan gated rectangular mold was investigated both experimentally and using the C-MOLD mold filling simulation package. Two polymers were used: Chevron LDPE 1409, which has a low viscosity and is inelastic and Dow PS 685, which is a high melt viscosity and melt elasticity (as measured in the linear viscoelastic range) polymer. The key conclusion of this study is that the simulation works for flows and polymer melts, where the applicable constitutive equations are for non-elastic melts whose material properties are evaluated from viscometric flows.
