Axis Rod device

The mandrel bender uses a metal shaft to contact and bend coated samples, observing the cracking of the coating. It is used to evaluate the flexibility and adhesion of coatings and inks on metal substrates. It is applied in quality inspection to assess the coating's resistance to deformation.
Selection
Select the diameter specification of the mandrel based on the thickness of the material being tested, determine the benchtop or handheld structure considering the laboratory space, verify the bending speed parameters required by the standard method, and check whether the surface finish of the mandrel meets the testing requirements.

Testing principle of the mandrel bending method for paint film flexibility tester
The shaft-rod bending method is a common technique for testing the flexibility of paint films. It involves bending a test panel coated with the paint film over shafts of different diameters to simulate the deformation of the coating under stress.
Paint Flexibility Tester for Measuring Bending Adaptability
The coating flexibility tester is a device used to assess whether a coating cracks or peels when bent. During testing, the coated sample is bent around mandrels of different diameters, and the surface condition is examined. The flexibility is evaluated based on the smallest mandrel diameter at which no cracking occurs.
