So, Samples are cut and deep draw according to Erichsen Principle to determine the depth to which they can draw before the paint cracks.
Cupping Test Apparatus
However, Hand operate, rugge ERICHSO TESTER is design to find the deep drawability (ductility) of metallic sheets and strips as per Erichsen Principle for cupping test.
Pressing the clamp test piece into a die by means of a ball or penetrator with a spherical end until rupture commences, measuring the depth of the cup.
