Bend testing tinplate.

The bending test for tinplate involves repeatedly bending the tin-coated steel sheet over a mold with a specific radius until it fractures, to examine the adhesion between the substrate and the coating as well as its ductility. It is used to evaluate the resistance of packaging materials to processing deformation, preventing issues such as coating peeling or cracking during can production.
Selection
When selecting, consider that the testing machine must accommodate a plate thickness range of 0.1–1.5 mm, and the fixture should be equipped with bending cores of different radii (0.5–3 mm). A digital display device is preferred, with a bend angle adjustable from 0 to 180° and a constant clamping force required. The specimen dimensions should be taken as a width of 20 mm according to the GB/T 235 standard.
