Erichsen Cupping Testing Machines · Canan Testing
The Erichsen cupping testing machine is a specialised instrument used to evaluate the ductility and formability of sheet metal. It presses a hemispherical punch into a clamped sheet until a visible crack appears; the depth of the cup at that moment is the Erichsen index.
We offer the ET 20 and the digital ET 20 D Erichsen testing machines for sheets 0.1 to 2.0 mm thick, with a least count of 0.01 mm.

The ET 20 and ET 20 D Erichsen testing machines perform cupping tests on sheet metals 0.1 to 2.0 mm thick, measuring cup depth with a least count of 0.01 mm.
Know the machine
The Erichsen cupping test checks how well sheet metal can be formed. A hemispherical punch presses into a clamped sheet until a crack appears, and the cup depth at that moment is the Erichsen index: the higher the value, the better the formability.
It is a fast acceptance test for deep-drawing steel, aluminium, brass and copper sheets used in automotive bodies, appliances and pressed components.

It is the depth of the cup, in millimetres, at the moment a through-crack appears in the sheet. A higher value indicates better formability.
Steel, aluminium, copper, brass and other metal sheets, typically 0.1 to 2 mm thick.
