Notizen:
Two models are presented for simulating the injection molding of thermoplastics in thin, rectangular cavities. One is a much simplified bounded-radial-flow model that utilizes an existing numerical model for semi-circular cavities to adjust for the non-radial flow region bounded by the lateral walls. The other is a two-dimensional analysis which assumes that both viscosity and temperature change strongly across the narrow gap but vary weakly in the directions of flow. The latter analysis allows application of the potential theory and the determination of streamlines and progressing front shapes. Both models deal with a non-Newtonian viscosity with temperature variation. Comparisons between experimental and computational results are shown.
