Applications:

The Cupping testing Machine ( Erichsen Tester ) is precise  technology testing machine which is used for sheet metal &  strip steel rolled stock etc. It can complete test of plastic deformation for 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-loading test force: 10kN, read & calibrate directly from meter.

2. LCD 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 encoder with resolution 0.001mm.

4. Test speed from 2 mm/min to 100mm/min can be set freely, variable speed. One test finish, then ready to be for next test automatically. Easy to be operated.

5. It’ll display test load of cupping test & cupping value.
