No.307 MIT TYPE FOLDING ENDURANCE TESTER
- This tester is used to evaluate the folding endurance of paper, cardboard, plastic film, and flexible print circuit boards.
- Applying a certain load and folding the test specimen left and right at a 135°angle at a certain speed, the operator is to count the number of times the test specimen was folded until it fractures.
- The deadweight method is adopted as the loading type for this tester.
- This tester is also used for evaluating the folding endurance of metallic foil such as aluminum foil used in condensers.
