1. The speed of a punch press moving up and down, it is an efficient method.
2. Deep drawing produces shapes with closed ends, it can avoid the need to cut and weld multiple pieces.
3. There are no joins for deep drawing that can make for anything that needs to be water or gas-tight.
4. If the tooling was made correctly,the deep drawing process conforms very close to the drawing.
5. Deep drawing can produce very strong parts, because it allows a certain amount of movement but beyond that it becomes locked.
