EQ-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 flexibility 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
