Judging solely off the name of the process, you might assume that “deep drawn metal stamping” is some kind of cool, 3D art using metal as the canvas and perhaps rubber stamps in some capacity. Alas and alack, you would be wrong—we all know what happens when you assume.
Instead of any kind of art, which seems implied by the use of the word “drawn,” deep drawn metal stamping is, in fact, a way to produce parts for cars, HVAC, and other uses out of sheet metal. According to the interwebs, the “deep” part literally means “deep,” as in the depth of the parts from top to bottom when finished. “Drawn” refers to the process used to form the metal, which is essentially just stretching it into the desired shape (“drawing”) using super-heavy machine presses. “Metal” is accurate in both your incorrect assumption and the real explanation—metal is the material used. “Stamping” is part of the title because the parts are stamped out of metal.
But, if you really wanted to make a confusing mess of things—or a messy confusion of things—you could take one of these metal parts and art it up with rubber stamps. Then, draw a highly-detailed picture of the stamped up metal—be sure to draw it all 3D-like so you can get a sense of the depth. And, somehow, draw it on a light colored sheet of metal. That would create a “deep drawn stamped metal deep drawn metal stamping drawing.”
Or something like that.
