Bending Stiffness Tester

Product line: S58566

For determination of the dynamic forces in a 2-point bending test. The bending stiffness tester was especially developed for the paper and automotive industry (VDA). To avoid falsifying influences, the tester is installed on especially developed antivibration dampers. A protection cover made of acrylic glass protects the measurements area. Sample clamping either happens pneumatically or manually with a torque screwdriver. The measurement length can be set as required from 1 to 50 mm. The touchscreen is used to select the test program and assign the samples to the corresponding test series (MD/CD, front side/ rear side, angle data, etc.) A comparison of the individual test series can be selected as needed. More settings are available like bending angle, dwell time, angle speed etc.

Test description

After preparing the sample with the punch, put it into the support. Close the acrylic glass cover, select your test program and assign your test to a test series. When you press the start button, the machine pushes the sample towards the measurement cell with precisely defined speed. When the pre-defined bending angle is reached, the sample remains in this angle for the pre-set dwell time. When the pre-set dwell time is over, the sample returns to the initial position. The touchscreen displays the testing results of up to three pre-defined measurement points. The results are displayed in values as well as in the form of a real-time diagram. If various tests of a test series were done, the results can be compared statistically, and the ratios can be displayed.
