Abstract
Methods for manufacturing a flanged article (21) that comprises a central depressed body (27) and a peripheral flange (23) may include press forming a material (10) in order to form an intermediate flanged article (20) that comprises a central depressed body (26) and a peripheral flange (22). Then, the peripheral flange of the intermediate flanged article may be circumferentially squeezed in order to thicken the peripheral flange due to plastic flow caused by plastic deformation. The press forming step optionally may include forming a toothed portion (24) on an inner surface (22a) of the peripheral flange. The squeezing step optionally may include reshaping the toothed portion. Apparatus (1, 2) for performing each of these method steps are also described.
