摘      要：In the extrusion of shapes with flat faced die,the proper design of die land is of critical importance in avoiding the generations of geometry defects.A methodology for the design of die land,which consists of a simulation adjustment iteration,is *** metal flow in extrusion is simulated by the three dimensional finite element method and the die land is adjusted according to the simulation *** the formulae for adjustment of the die land and the criterion for the judgment of proper die land are *** extrusion of an L section shape is chosen as the computational example and the result is compared with the industrial design.
