Mandrel Bend Testing
A coated metal sheet is bent over a conical or cylindrical mandrel and cracks, color change, adhesion etc. of the coating are evaluated. Corresponding results, produced by decreasing mandrel sizes, indicate the degree of elasticity of the coating. A conical mandrel allows the user to undertake fewer tests to achieve a similar result to cylindrical mandrels.
