MIT folding endurance tester

This machine counts the number of folds, which a specimen will withstand before break. The upper end of specimen is secured with the loading spring clamp and the other end with the folding clamp. The loading clamp applies a constant tension on the specimen. In this state, the folding clamp reciprocates to repeatedly fold the specimen till it breaks. The number of reciprocating actions counted is shown
- Specification
- Standard
- Model
– The reciprocating part is provided for silent operation and reduced heating up
– The specimen is set on the upper chuck from the chuck front.
– The lower chuck returns to start position automatically when the specimen breaks
– Cooling fan (option)
– Specimen tension : 5 to 15N , standard 9.8N
– Rotation speed : 175 ± 10 times/min
– Folding angle : 135 ± 2 in each direction
– Chuck : 0.25mm (standard), 0.5, 0.75, 1.0, 1.25mm (additional chuck optional)
– Folding number indicator : digital counter with six digits, with automatic stop mechanism working on specimen failure
– Folding endurance indicator: it displays a logarithm
