Abstract: Abstract A model for the filling stage of injection molding of viscoelastic thermoplastics in cavities of complex shape is presented. The model considers two‐dimensional melt flow, with converging and diverging flow patterns induced by complex boundary shape and by the presence of an obstacle. The model is non‐isothermal (with the melt loosing heat to the mold walls as it travels into the cavity) and handles a viscoelastic (following the White‐Metzner model) material with properties that vary with temperature…
