Abstract
A press working method and related metal parts for forming a metal part (1) of a geometric shape such that several regions need to be deformed in opposite directions during press working. The press working method includes the step of preparing a blank laminate (10) having at least two subblanks (101, 102) corresponding to subparts (11, 12) of a metal part, the blank laminate further comprising an overlapping region (100) in which the blanks are superimposed on each other, the overlapping region (100) corresponding to a critical transition region 11T12 between the two subparts.
