Erichsen cupping test for sheet metal includes placing the metal sheet in the machine and punching a cup into the sheet until a crack appears.
Erichsen cupping test for sheet metal.
Erichsen was the development of a special tool for deep drawing cup test in 1932.
Based on the standardized erichsen cupping test a load cell and a high resolution distance measuring system have been integrated into a specially developed tool.
It is very simple.

Erichsen cupping test the sheet metal specimen in the form of strip is inserted into the test cylinder and centralised by locating diagonally.
Remove a piece of sheet metal.
Using intelligent self learning evaluation software it is possible to make a statement on the suitability of the sheet metal within a few minutes.
A visual inspection is done to see if the test material has developed any cracks or deformity.
The cupping test for metal sheet thickness range is 0 1mm 5mm max.

To punch out round disks from sheet metal strip and then use it to shape it with a drawing.
There are two most commonly used erichsen cupping test standards.
Then the depth of the cup is measured and eventually ductility is measure as a function of this depth.
