Cone bending tester

Purpose and Application

The cone axis bending test is a very common testing method used to measure the flexibility and adhesion performance of coatings under bending stress.

312The cone-shaped shaft bending tester meets various testing standards.

Testing Principles

The cone axis bending tester is used to determine the largest cone axis diameter at the surface fracture point of the coating after bending.

overview

312The type axis bending tester is a compact and sturdy instrument made of enamel steel, suitable for use on stage. The tapered shaft and the shaft rod parallel to the surface of the tapered shaft are made of stainless steel. The clamping device is equipped with an eccentric rod to ensure quick and simple sample replacement.

Test program

Bend the rod towards the clamping device until it reaches the stop position. Test piece(Coating outward)Insert into the clamping device between the cone shaft and the pressure roller, and push to the end of the smaller diameter cone shaft, using a cam rod to fix the sample.

Please note that:

A piece of paper can be inserted between the sample and the pressure roller to avoid scratching sensitive paint surfaces.

In about2~3Rotate the bending rod smoothly around the axis within seconds to bend the sample, and then check for coating rupture.

The test result is described as the length from the end of the thin shaft to the point of rupture or as the diameter of the shaft at the end of the rupture.

Please note that:

The shaft diameter in inches can be converted using the scale on the clamping device and the table below.
