ABSTRACT:
A simpler and less expensive method of fabricating pressed components from sheet steel that can be heat treated while inside the press, whereby the material is heated to above its transformation point Ac3, pressed, and cooled, controlled, to below its crystalline-transformation point. The sheet is unwound from a coil (1), heated to above its transformation point, pressed in a press, and separated.
