Cupping tester
The cupping tester has been designed for determining the elongation and deformability of single- and multiple-layer systems on metal substrates.
- Electrohydraulic drive for highly reproducible results
- Easy to use eccentric clamping ring
- C-opening accepts large and small test panels
- For test panels with a thickness of up to 0.06 in (1.5 mm
- Uniform cupping speed of 0.008 in/s (0.2 mm/s)
- 3 keys to control all functions
- Digital display, resolution 0.1 mm
Stereo Microscope for cupping tester
This stereo microscope with illumination and brightness control is designed to observe the paint surface during the test.
- 2x and 4x magnification
- 3D-image with shadowless illumination
- Ergonomic working position
Procedure
– Insert the test panel into the C-opening of the instrument
– Clamp in the sample firmly
– Start cupping and simultaneously observe the process through the stereo-microscope
– Apparatus presses the cap of the spherical punch into the test panel at uniform speed (0.2 mm/s)
– As soon as the first cracking is visible, stop the movement of the punch
– Read the cupping depth on the digital display and reset the punch
– Always carry out 3 tests for each sample
