In this paper, the radial-forward extrusion process in the enclosed dies to create precision parts is considered. The numerical simulation techniques by using the rigid-plastic finite element method (FEM) as software QForm 2D have been applied to investigate in this paper. Based on the finite element simulations, forming characteristics such as patterns (gridlines distortion), distributions of effective strain and stress at several stages of process with different forming parameters, the relative pressure variations on the punch with different relationships parameters and also to predict and avoid folding defect in radial-forward extrusion process have been investigated by using this numerical simulation method.
