Abstract:The technological feature of the continuous extrusion forming (ConformTM ) 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 ConformTM process and the temperature, strain and stress fields were gained.
Key words: continuous extrusion forming; modeling; computer simulation
