POLYFLOW Extrusion (Viscous Isothermal)

Test ID  
G-310

    
Description  
Properties needed to perform an extrusion simulation are generated. These include viscosity vs. shear rate data at the processing temperature and solid density. KBKZ model fitting for Polyflow is performed.    
Included Tests  
# Test Id Test Name
1x D-015 Melt Density
1x R-011 Capillary Rheology (1 Temperature)
 
Data  
Measured property data is provided. A Polyflow input-file is provided.  
Samples  
1 - kg of pellets [?]
 		   
Application  
Simulations of isothermal extrusion applications may be carried out. This represents the simplest level of POLYFLOW simulations and may be used for non-temperature sensitive materials or where the temperature gradients in the configuration being simulated are not large. Visco-elastic effects are assumed to be insignificant.
