Ueshima - Erichen Tester



It is a testing machine that measures Erichsen value of metal thin plate (0.1 ~ 2 mm). In the test method, the spherical punch is gradually pushed into the test piece fixed between the blank holder and the die until the through crack occurs, and the indentation depth (Erichsen value) is measured and compared at the time of the through crack occurred. In addition, the same test method can be used for the cupping resistance which is the evaluation of the adhesion of the coating to the metal plate.
