4) In the deep drawing of cups, blanks show a tendency to wrinkle up around the periphery (flange). The most likely cause and remedy of the phenomenon are respectively: Buckling due to circumferential compression; Increase blank holder pressure. High blank holder pressure and high friction; Reduce blank holder pressure and apply lubricant. High temperature causing an increase in circumferential length; Apply coolant to blank. Buckling due to circumferential compression; decrease blank holder pressure.
