MIT Folding Endurance Tester

       PN-NZ135F MIT Folding Endurance Tester is a paper folding resistance tester developed according to the national standard GB/T 457 and ISO 5626. It is suitable for testing the folding resistance of paper, cardboard and other sheet materials with a thickness of less than 1.25mm.  MIT fold resistance is the logarithm (base 10) of the number of double folds when the paper sample is broken under standard tension conditions. Folding resistance has a great impact on the flap of the carton. Some cartons often have the flap broken, which affects the outer packaging of the product.
       The tester is a mechatronic tester. The mechanical part includes a motor transmission part and a tension mechanism part. In terms of mechanical transmission, the connecting rod is controlled by the motor to control the clamp to rotate left and right by 135 °. The speed of the motor is controlled by a governor and a circuit. The tension mechanism deforms the spring by pressing the tension lever. The spring tension formed exerts a force on the paper sample to be tested, and the tension acting on the sample is adjusted between 4.91N and 14.72N. The tester can count the double folding times of the tested paper sample through the detection of the photoelectric circuit, and automatically stop when the sample breaks. At the same time, the tester also realizes the automatic return of the folding clamp through the detection of the photoelectric circuit. It is suitable for measuring the folding resistance of various paper and cardboard, and is an ideal testing equipment for industries and departments such as papermaking, packaging, scientific research and product quality supervision and inspection.
