    You wrinkles were caused by too much space between the upper and lower parts of your punch….. also the thinner the material the closer in diameter the punch,( upper ) and die ( lower ) must be. Tooling die clearance is 7-10% of material thickness, so material of .004 thich get less than .0005 clearance. How bout that, LOL
