Predicting how a molten material flows in a mold, can be very complex. There are several models that have been developed to help with this prediction, which vary in the dependencies they consider and the molding process they address.
Topics in this section
Simulation models (Procedure)
You can select the most appropriate model from several different viscosity models. Parameters for simulation models can be adjusted.
Cross-WLF viscosity model
The Cross-WLF viscosity model describes the temperature, shear rate, and pressure dependency of the viscosity.
Matrix viscosity model
The matrix viscosity model is used to determine the viscosity from measured data supplied at specific temperatures, shear rates, and pressures.
Moldflow second order viscosity model
The Moldflow second order viscosity model describes the temperature and shear rate dependence of the viscosity using a quadratic formulation.
Coolant viscosity model
The viscosity, flow rate, and Reynolds number of a coolant are interrelated.
