Product Description

Erichen Supping Tester

The Erichsen Cupping tester is used to assess the deep drawing quality of metal sheets and strips. This test can also be used for the paint film to cracking and/o detachment from a metal substrate whrn subjected to gradual deformation by indentation This is done by pressing a ball penetrator into a test specimen held between two flat surfaces until rupture commences or film cracks and measuring the depth of cup formed, which is a measure of the quality of the material or the film.

The "JUSTY" Erichsen Cupping Tester consists of a die, retaining ring, and a ball penetrator. The die and retaining ring are made from high carbon high chrome die steel and are hardened and ground to the specified dimensions to give a long operational life. The test specimen is in shape of a strip and is held between the die and the retaining ring. The die, which is mounted in a screwed ring, is brought in contact with one face of the test specimen is then pressed from one side by the ball penetrator, consisting of a hardened and ground carbon steel ball and back up rod, to from a cup.

The equipment is ruggedly built on a fabricated metallic base and is finished in bright chrome plating and hammertone painting.
