polyXtrue Monoextrusion module

polyXtrue Coextrusion module

optiXtrue extrusion die optimization software

PELDOM elongational viscosity estimation software

eXtruemat software

Quickly and accurately determine:
    velocity
    pressure
    temperature
    shear rate
    elongation rate
    shear stress
    elongation stress
    streamlines (for each polymer)
    residence time (for each polymer)
    post-die extrudate shape
    layer structure in final extrudate*

OptiXtrue automatically optimizes extrusion die geometry. It eliminates the need for virtual fine tuning of the die geometry by the user after each flow simulation in polyXtrue.

You will obtain:
An optimized die geometry for your extruded profile. The die geometry will be optimized for the minimum extrudate distortion.

You will provide:
Initial geometry of the die in SolidWorks or Inventor Software. You will parameterize, that is, designate as variables, some of the critical dimensions of the die which have the maximum effect on exit velocity distribution. You will also specify the range for each of the parameterized dimensions.

                       Elongational Viscosity Estimation Software

You will determine:
      Axisymmetric elongational viscosity using entrance loss in capillary rheometer
      Planar elongational viscosity using entrance loss in slit rheometer

You will capture:
      Elongation thickening followed by elongation thinning behavior of the viscosity

       Software for Estimation of Shear Viscosity Parameters

                You will accurately fit:
                      Shear viscosity model to experimental viscosity data

                Viscosity models allowed:
                      Carreau or Cross model for shear thinning behavior
                      Arrhenius or WLF model for temperature dependence
