GBW-60C Computer Control Ductility Cupping (Erichsen) testing machine+Metal Sheet Testing Machine+Forming Limit Curve Testing Machine
Main Applications:
The cupping testing machine is used to test extend and stretch capacity of metal thin plate and band. It is the only instrument to test the metals plastic deformation. The machine accords with GB4156-84. Also it can be used to test non-ferrous metals anisotropic character if adding impact cup mould. The machine adopts closed loop control and constant speed loading, so the test procedure can realize variable speed.
