WebNov 8, 2024 · Learn How Sheet Metal Deep Drawing Process Works. The process of sheet metal deep drawing involves multiple steps. The key steps are as follows: Sheet metal deep drawing process. Step 1: Blanking And Die Placement. Blanking is a process in which you separate a workpiece from a metal sheet. Then you subject it to press or die. Webdrawing the process becomes one of pure stretch-forming. Extensive and detailed experimental and theoretical investigations of cup-drawing have been carried out by different researchers, aiming at reducing the different defects in the process and improving the quality of the produced parts, [2-35]. 2.
