In view of the failure of ABS steel extrusion die in a petrochemical enterprise, the finite element software was used to simulate the die runner and the main reason of die failure was that the pressure drop exceeds standard. In this paper, in order to reduce the die pressure drop, improvement schemes are proposed. Firstly, increasing the entrance radius of the manifold can reduce the die pressure drop and the outlet velocity distribution is more uniform. Then, improving the height of sector can significantly reduce the pressure drop but the speed of the export sector becomes more uneven. Through the simulations of the invalid die which key parameters were changed, the rules and trends of the influence the various factors have are obtained quantitatively. This paper provides a reference for the design of the similar coat- hanger die.
