초록

In the present study, several design parameters of the flat-die extrusion process are investigated using the finite element method. The effects of the location of an extrusion profile, arrangement of multiple extrusion profiles, and the design of various die land have been investigated through the analysis. Several numerical examples of flat-die extrusion of such as C-section, multiple U-shape, and a window guide section, are analyzed. From the comparative study, the effect of design parameters is investigated. In each example, comparing the velocity distribution with that of the original design, it has been shown that the design modification affords more uniform distribution.
