The drawing of the parts inner forms, where the blank cannot feed the volumes created, is particularly difficult to realize. This is for example the case of inner plunged boss.
Important multistage drawing is necessary to realize these parts. Due to the stretch mode of the first drawing stage, the total drawing stage number can be doubled, compared with a first drawing in drawing mode (first drawing mode).
