The double cup extrusion test was developed and used extensively for evaluating lubricants in cold forging. This test emulates the high material/tool interface pressures and large surface expansion that occur in industrial cold forging operations. This short paper summarizes the principles of this test and illustrates how it is used to evaluate environmentally friendly lubricants.
