Abstract: The technological feature of the continuous extrusion forming (Conform TM ) process was analyzed and the computer simulation models, including geometric, material, plastical, frictional and heat transferring models, were built. The models were used to predict the deformation behavior of Conform TM process and the temperature, strain and stress fields were gained.
