Product Overview
Viscoelasticity
Plastics (Polymeric) fluids are often called viscoelastic fluids because they have both viscous and elastic properties. The viscoelastic effect is dependent on different temperatures and shear-rates. At filling stage, flow field varies severely, and viscous property of polymer dominates flow behavior.
Moldex3D Viscoelasticity software can predict the frozen flow-induced stress near the mold surface due to fast solidification caused by high cooling rates during filling. As solidification keeps developing during packing, the high temperature remained by solidification within the mold helps to release the stress. However, flow-induced stress may develop in the central area near the gate due to additional shear flow during packing. Different cooling efficiencies at different cooling processes would also affect the stresses relaxation. Above conditions during injection molding process can all be well caught and predicted by Moldex3D Viscoelasticity
