The biggest difference between single-action drawing and double-action drawing is that the double-action press can provide blank holder force through a separate mechanism, and the blank holder force of single-action press is provided by the reaction force acting on the blank holder ring when the female die goes down.

The biggest difference in appearance is that the female die of the single-action press is above, and the blank holder and punch are below.

The punch of the double-action press is on it. When moving, the blank holder moves first, and then the punch moves after the blank holder.
