Abstract
A system and a method for generating die swell/draw down information for a profile extrusion die design. A rheometer having a slit die and a puller mechanism coupled thereto provide the die swell/draw down information of a polymer resin material in two dimensions—in the thickness direction and in the width direction. A processor uses the die swell/draw down information to generate a die design chart that contains representations of shear rate, draw rates, and thickness. A designer uses the die design charts to design a profile extrusion die.
