MIT TYPE FOLDING ENDURANCE TESTER
Overview of 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.
