Tension-Free™ U-shape Folding Test [DLD-FS]

Desktop Model Endurance Test Machine
Tension-Free™ U-shape Folding Test

The bending load is applied by having one side of the sample move straight towards the other side. The sample only receives bending load so there are no applied tension or friction.

YUASA SYSTEM won the FLEXI Award in the Product Innovation category for Tension-Free U-shape Folding Test Jig. The FLEXI Award is presented by FlexTech, a SEMI Strategic Association Partner.

Issues During General Folding Test

When conducting tests with equipments shown in the below diagram, a large tension occurs on the sample when the test starts. The cause of this is clear when drawing a circle with radius the same length as the sample on the movement track of the test machine, shown on right. As shown in red in the diagram, the length of the sample is too short against the movement track of the clamp. If one uses a rod, this becomes more apparent. This causes the unexpected breaks and disperse in the test results in actual tests.
