Thanks for help.
The dies shape designed and cnc miled with 1 mm ( about 1/32 inch) gap between up and down.
Before shtinking i move down the upper die till it touch the lower one.
I got a piece of rubber on the middle of upper die. Maybe it's too soft and cant give enought power to stroke.
I will grind a flat place and write about results.
