This test machine can examine by tiny bending radius.
This test method doesn’t occur the tensile stress to the test sample.
This test jig can realize the tiny bending radius test without tensile stress because test sample is kept by the 2 plates of double-joint clamshell.
Two plates keep the test sample, and then one plate operates by Rotary Reciprocation Axis. This two plates move open and close keeping each angle by the parallel link structure.
A safety cover is available for the flexible area as an option.
It is possible to evaluate by tiny bending radius without tensile stress to the test sample by using Tension-Free™ Folding Clamshell-type Jig. (patent pending)
The plate can remove with leaving the test sample on the test jig, so if you inspect by microscope it is easy to restart the test with the same situation.
