Abstract

In this work, we aimed to develop an optimum design for a spider die used for the extrusion of high‐density polyethylene tubes. For this purpose, a computational‐fluid‐dynamics‐based model using the generalized Newtonian approach was employed to investigate the pressure drop, flow, and temperature uniformity in the die. © 2011 Wiley Periodicals, Inc.
