Recent Developments in the Manufacture of Complex Components by Influencing the Material Flow during Extrusion

Article Preview

New innovative direct extrusion process variants, curved profile extrusion (CPE), twisted profile extrusion (TPE), and hollow profile extrusion (HPE), which increase the flexibility of aluminum profile manufacturing processes, are presented in this paper. These processes are characterized by influencing the material flow inside the die so that the forming process is completed when exiting the die. On the one hand, three-dimensionally curved profiles are produced and analyzed by CPE regarding the accuracy, the influencing parameters, and the compensation strategies. On the other hand, TPE and HPE make it possible to manufacture helical profiles usable, for example, as screw rotors in fluid machinery.
