Plastic Flow's expertise in simulation of polymeric flow including the effect of shear as well as elongational viscosity of the polymer is available to you for trouble shooting, design and optimization of polymer extrusion and injection molding. It is particularly important to include the effect of elongational viscosity for simulation of the flow in extrusion dies, including flat dies, spiral dies and profile dies, because the flow in most extrusion dies and twin screw extruders is highly elongation dominated. If the effect of elongational viscosity on such elongation-dominated flows is neglected, the predicted velocity, pressure and temperature distribution can have as much as 50% error.
Juncture losses in an injection molding runner system are also because of the high elongational viscosity of polymers. Plastic Flow offers consulting services for full three-dimensional simulation of injection molding including the prediction of core deflection during the molding process.
