Abstract
A punch for simultaneously pressing two or more different powder formulas has a punch body with a first region and second region. The first region is comprised of a first material and configured to apply a first predetermined pressure to a first powder formula when a ram force is placed on the punch body. The second region is at least partially comprised of a second material and is configured to apply a second predetermined pressure to a second powder formula when the ram force is placed on the punch body. The second material is less hard than the first material such that the second predetermined pressure is less than the first predetermined pressure.
