| Abstract |
Curved Profile Extrusion (CPE) is an extension of the common extrusion process and
offers the possibility to manufacture three-dimensionally curved profiles. Due to the flexibility of
the process different curvatures can be produced with the same setup, which makes this technique
efficient especially for low volume production. The process is characterized by a controlled lateral
deflection of the strand which influences the material flow in the die and causes the profile
curvature. In this paper, a direct comparison of the power rating between warm bending and CPE is
presented. Furthermore, the investigations concerning the choice of support strategy of the
surmounting profile by a robot to increase the curvature accuracy are continued. Finally, some
extensions of the equipment are explained to increase the level of process integration. |
