EBway Corp. has designed a compound stamping die to reduce the amount of die roll on pierced holes. Die roll is the slightly curved contour on the edge of one side of a blanked part, created by the amount of pull-down on the part material before the actual cutting of the material starts.
Developed to solve a particular customer's concern, the technology now is available for use on materials from 0.060 to 0.500 in. thick.
