This paper provides a principle optimizing the coat hanger die with the tear shape manifold and a method simulating the distribution of pressure in the die cave. Based on this,a CAE software is worked out.The effect of each geometry parameter of the die cave on the distribution of pressure is analyzed.This principle has been used in industrial practice.As the result of the practice, this method has been proved to be efficient in the designing and the trouble diagnosis for the die, and has a wide foreground.
