Abstract	Local thinning inevitably takes place in sheet metal forming. This can be prevented by the application of a compression load during wall-thickening forming, through which a part can become even thicker than the initial sheet material thickness. Wall-thickening forming is advantageous for the manufacturing of cup-shaped products and products with bosses. This study suggests a progressive process design procedure for the wall-thickening forming of a door lock striker with double bosses. The proposed procedure involves first drawing, redrawing, and upsetting. The design of the progressive process is performed with the suggested design procedure using finite element analysis. To verify the result of this study, an experiment for manufacturing door lock striker with double bosses was performed by the progressive process. The results of the experiment for the measurement of the thickness at the bosses showed good agreement with those of the finite element analysis. From the experimental result, double bosses with a thickness distribution of 2.25–4 mm can be manufactured from sheet metal with an initial thickness of 2 mm using wall-thickening forming, which results in an increase in the strength at the bosses by about 27 %.
