Finite element modelling has been used to study the effect of conical die angle, tube diameter and material behavior both external and internal inversion for aluminum tube. 3D finite element model was used to build the contact pair for the aluminum tube and the conical die. Due to the axial symmetry a 45o sector for the contact pair has been chosen. It has been found that there is a significant role for conical die angle to govern the inversion process and the mode of deformation beside the value of the applied force. A local buckling takes place in the internal inversion for all half die angles.
