Abstract

In the present study, several design parameters of the flat-die extrusion process are investigated using the rigid-plastic finite element method. The effect of loaction of extrusion profile, arrangement of multiple extrusion profiles, and design of various die land has been investigated through the analysis. Several numerical examples of flat-die extrusion, such as C-section, multiple U- shape, and window guide extrusion, 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 much more uniform distribution of axial velocity
