MBT-12-LD is a manually operated Mandrel Bending Tester with 12 pcs various size cylinders, including 2,3,4,5,6,8,10,12,16,20,25,32mm diameter. It is suitable for testing the flexi bility of battery electrode sheet or film. Specifications: Features Used to test the resistance of a coating of the electrode to cracking or detachment from a substrate. after coating, the film has been bent around a cylindrical mandrel. It can be used as a simple Pass/Fail test at a known diameter by using successively smaller mandrels until cracking is observed. Accepts up to 50mm wide and 1mm thick sheet can be tested. 12 pcs stainless steel cylinder are included with diameter: 2,3,4,5,6,8,10,12,16,20,25,32mm diameter. Procedure Apply the paint film on sheet metal strips Coat and dry film carefully to ensure reproducible results For testing, uniformly bend the coated samples over the bending mandrels within 2-3 sec at 180 degrees. Start with the largest bending radius, the test is continued until reaching the bending radius at which film shows crack Show more
