You have to consult the mold master. I can't tell you clearly. The difficulty of this kind of annular compound die lies in that the wall thickness of only one side is 3.6MM, and it is difficult to punch down a 3 cm iron plate. The mold must be inverted, and a gap between the female mold and the male mold must be made. .

MD！ I almost got cheated by you. The inner ring is 3* 15mm, and the outer ring is 3 cm thick. Are you kidding? This structure simply won't work. Shit! I almost saw 3MM! Your product needs instrument car production! ! ! Dizzy! I'm also a good mold maker.
