METAL BLANK WITH BINDER TRIM COMPONENT AND METHOD

摘要

A metal blank (10, 100, 210) that includes a binder trim component (40, 240) having at least one cut edge (24, 26, 102) with a non-linear section (250). The creation of the nonlinear section (250) simultaneously forms a corresponding section in a binder trim component of an adjacent metal blank so that binder material can be shared therebetween. This reduces the amount of scrap metal, as the binder trim component (40, 240) is subsequently cut off and discarded. Furthermore, the non-linear section (250) can include one or more strategically placed formations, such as projections (50, 60, 104, 246, 248, 252, 260), recesses (52, 62, 106, 254, 262, 266, 268), flat sections (256, 258), etc., that cause it to be non-uniform along its length and to be specifically tailored to the manufacturing requirements of the part being formed.
