The bodymaking of D & I can consists of a deep drawing process, a redrawing process and a multi-stage wall ironing process. From the viewpoint of mechanics, it can be classified into a complicated high-speed forming process, including nonlinear and coupled thermal-mechanical contact problem. In this study, an axisymmetric non-isothermal finite element analysis using the FEA code ABAQUS has been conducted to analyze the continuous steel D & I canmaking process from deep drawing to three stages of wall ironing. Information on punch load histories, stress/strain distributions and temperature increases are obtained from the analysis. To compare the results from the FE analysis, canmaking experiments utilizing a pilot canmaking line are also carried out. The material considered is a tinplate, a type of low carbon steel for the commercial production of steel D & I can.
