Applications:

The Cupping testing Machine (Erichsen Tester) is precise technology testing machine which is used for thin sheet metal & strip steel rolled stock etc. It can complete test of plastic deformation for thin sheet metal & strip steel rolled stock.

Standards:

It conforms to ASTM E 643-78 & GB4156-84 “Testing Machine for Metal Cupping test”

Features:

1. Pre-clamping load: 10kN, read & calibrate directly from the computer.

2. Computer screen display test load from 600N to 60kN in real time, the test accuracy is ±1%.

3. Resolution of Load cell & signal is more than 1/100000, measuring displacement with resolution of 0.01mm.

4. Test speed from 0.05mm/min to 200mm/min can be set freely, variable speed. One test finish, then ready to be for next test automatically. Easy to be operated.

5. The machine will show Clamping load, punching load, displacement and cupping value,  test speed, test curve, etc.
