ERICHSEN CUPPING TESTER (MANUAL)
Overview of ERICHSEN CUPPING TESTER (MANUAL)
This tester is used to evaluate the cupping endurance of the coated film.
Fixing the test specimen between the holder ring and the dice, the operator is to give the test specimen a pushing load to evaluate the endurance against cracks and peels of the metallic substrate when the test specimen receives a partial transformation.
