Model GBW-60B Erichsen Cupping Testing Machine
Application & Functions
The Erichsen cupping testing machine is mainly used for testing the plastic deformation performance of the sheets and the thin strips in the process performance test of metal sheets and thin strips.
The testing machine can meet the requirement of international standard ISO 20482: 2003 Metallic materials-Sheet and strip-Erichsen Cupping Test and Chinese standard GB/T4156-2007 Metallic materials-Sheet and strip-Erichsen Cupping Test.
