Cylindrical Mandrels

Elasticity and resitance to deformation are part of the key physical properties required in the coatings industry. Essentially there are three different test methods which are used to determine a coating\'s performance under different deformation conditions.

Bend Test A coated metal sheet is bent over a cylindrical or conical mandrel and the coating observed for cracks and discolouration.

This cylindrical mandrel bend tester consists of a robust frame which has a bending lever, with height adjustable rollers and a sliding vice for the sample. Thanks to its design, the instrument can be adapted to the diameter of the mandrel used are bent perfectly and regularly over the mandrels

Cylindrical Mandrel: The test plates are bent progressively over mandrels of decreasing diameter until cracks appear. It incorporates mandrels of the following diameters: 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25 and 32 mm.
