Cylindrical Mandrel Bend Tester

This sturdy and robust unit is designed to test and determine the elasticity, adhesion and elongation of dry-cured paint or coatings on a metal sheet.
Manufacturer: Bevs
SKU: CA-23300

The Cylindrical Mandrel Tester CA-23300: Coated Test Panels up to 2.75" (70 mm) in width are bent over your choice of mandrel size (2-32mm) by regularly decreasing the mandrel diameter until cracks are observed on the test panel. The mandrels can be adjusted for height and the vice can be adjusted forward and backwards to achieve perfect bends continuously. Thus each panel can be bent perfectly on different diameter mandrels.

Each Cylindrical Mandrel Tester includes 14 mandrels with diameters of 2, 3, 4, 5, 6, 8, 10, 12, 13, 16, 19, 20, 25 and 32mm.
