MIT Folding Endurance Tester provides a specific load and in a angle of ±135° to fold the specimen. When achieve the specific times or specimen broken or short of electric power, this tester will auto stop and record the times.

For testing the folding endurance for materials of circuit soft board, copper foil, paper etc., both sides (left and right) of folding testing angle can be set on 90~135 degree and testing speed 175 times per minute. The tester would stop automatically and record the folding times when specimen is cleavage. This tester also can open circuit to stop the machine working function by voltage loop detect. This tester is available to change folding R angle and clearance by different grip.
