In present, the automotive and aircraft industries, give a lot of attention to plastic materials due to the advantages of light weight, low cost, and extra strength. Although the metal gas forming is a well-known process, the plastic tube forming is a quite new area of research. In this paper, the FEA of the tube forming process of polypropylene tube with different material properties and process parameters and the following multivariate statistical data analysis is presented. The FEA is

The quality of the final product is introduced as a tube wall thickness distribution along the length of the tube. The product quality dependence on the material properties and process parameters will be illustrated in this research. Also a technique of the optimal tube wall thickness distribution is proposed. This technique allows to adjust the manipulated variables trajectories, such as temperature, strain rate, internal pressure and axial displacement.
