Talk:Impact extrusion

vs. deep drawing?
From How It's Made I've seen aluminum baseball bats made by what they called impact extrusion. I believe I've seen the process for making tall metal water bottles called deep drawing. Is there a well-defined difference? Both seem to be capable of producing amazingly tall parts with thin walls and zero draft angle. —Ben FrantzDale (talk) 12:25, 9 July 2012 (UTC)
