The B0013 MIT FRIST manufactured by IDM company, under a constant pressure load, the flexible material sample is doubled at a fold angle of 135 ° and 175 times / minute speed until the sample breaks. Paper, leather, fine wire and other soft materials have lower tensile properties, and the auxiliary test folding strength is more practical for the production and application of the material. This machine accepts a standard 14 cm and a 9 mm sample size, which can accept changes in the sample thickness from 0.01 mm to 1.00 mm (shading size requirements, can be customized separately.) Main application: Measure the sample under the action of fixed tension, the sample break is the maximum number of bendings that can be affected by the sample. It can be used to test the ability of paper jams, map paper, banknote paper and other materials to withstand repeated curvature; can also be used to assess various types of paper, cardboard due to time, temperature and humidity, etc. And the ability to detect. Since the test fixture is much specified, the thickness and material range of the test is wide. In the test, the ability to fold the strength of some samples may reach thousands or even 10,000 times, and this instrument detects and displays the maximum number of folds through an optical sensor. Since the resistance of the gear reciprocation is minimized, there is a very low noise when operating, and the structure of its stainless steel is ensured, ensuring more robust durability.
