Drawing force test
WebA proper blank-holder force can prevent wrinkling of the drawn cup and delay necking. A blank-holder force profile which starts from zero at the beginning of drawing and reaches a maximum, and then reduces to zero at the end of the process is desirable for minimizing frictional resistance at the flange area and eliminating wrinkling.
