摘要：Coat-hanger dies are widely used in the extrusion of plate and sheet, since it can achieve uniform velocity attribution on the outlet according to balancing the distribution of flow through the die. A failure ABS extrusion die of a petrochemical company is studied in this paper through the method of numerical simulation which was done by finite element software Polyflow with structured grid meshed by ICEM. The results show that the pressure drop in the die exceed the maximum allowable value, which is the main cause of die failure, in addition to the exceeded pressure drop the fluctuation of the velocity on the outlet is too large, which would lead to poor quality of product. The work in the paper provides guidance for the future die design and optimization. (C) 2015 Published by Elsevier Ltd.
