GBW-60 Computer Control Cupping (Erichsen)Testing Machine 

Introduction:

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 ISO 20482-2003 and GB/T4156-2007. 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.

Standard:

The machine accords with ISO 20482-2003 Metallic Materials-Sheet and Strip-Erichsen Cupping Test and GB/T4156-2007.
