Abstract
A method for making a projection on a metal panel includes providing a lower die having a recess in the shape of the desired projection, laying the metal panel atop the lower die, positioning a filler material atop the metal panel, and lowering an upper die onto the filler material so that the filler material is forced into the metal panel and in turn forces the metal panel into the recess of the lower die whereby a projection is formed and the projection is filled with the filler material.
