1, the most labor-saving way, on the drawing, mechanical drawing, can be two-dimensional (such as AutuCAD), can be three-dimensional (such as Solidworks), draw a stamping pattern or process drawing on the computer, and then print the graphics to reflect stamping. But it is difficult for you to form an animation unless you have more than 20 pieces of paper.

2. If it is complicated, wet the drawing, coat it with ethylene lubricating film, put it into the mold for stamping, and take it out after drying, which is the effect you want.

Of course, after reading your question carefully several times, the above answer may be just for fun.

You want to ask: the product graphics you drew are obtained by stamping, how to show them in technical drawings?

Then you can: first, draw a blank drawing (blanking drawing), second, draw a molding drawing, third, explain the processing technology in words, and fourth, point out the mold used.
