Cupping (Erichsen) Testing Machine

Our offered Cupping (Erichsen) Testing Machine is used to test extend and stretch capacity of metal thin plate and band. It is the only instrument to test the metala s plastic deformation. Also it can be used to test non-ferrous metala s anisotropic character if adding impact cup mould. The machine adopts high precision raster measure instrument to test Erichsen value so it has a high testing precision. It adopts the electric control machinery onload and LCD spoke sensor so it raised the testing precision of the main test force and accuracy of controlling sample breaking.
