Wanted to press punching of 0.22mm dia (Bottom) and on (top) 0.6mm dia

Please suggest how can I make such die?

  • What concerns do you have? Why do you think that this will be an issue? – hazzey Mar 21 '18 at 12:28
  • I suggest you don't make a die to punch a 0.009 " ( I only think in English) hole in tough stainless steel ( assuming 304 or 316 ). Are you trying to make a die for extrusion ? – blacksmith37 Mar 21 '18 at 21:54

    @blacksmith37 when the question was asked in metric, why answer in imperial? Then double down when an explicit statement about it? – DrMrstheMonarch Apr 15 '20 at 10:25
  • I practice both units, but always find it is difficult to visualize metric size in my head, I believe the reverse is true for many people. – r13 Dec 06 '21 at 03:20
  • The point is , you can't make a punch that diameter regardless of whether you call it mm or in. – blacksmith37 Apr 05 '22 at 14:05

You could "micro metal etch" the pattern either onto a stamp or onto a die. This kind of thing is done by these companies:
