It is the only instrument to test the metal’s plastic deformation. Also it can be used to test non-ferrous metal’s 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.

 

Parameter:

Max testing force: 60kN;

Testing force range: 0.2kN～60kN;

Accuracy of test: ±1％;

Testing speed: 2～100mm/min  (at any speed constantly speed control)

Puncher cupping mould: φ20±0.05;

Thickness of sample holding: 0.05～2mm  (with high precision sensor, it can achieve ultrathin plate test. Special order: non-standard cup:0.05~3mm; non-ferrous metal plate:0.1~2mm)

Distance of puncher moving: 40mm;

Distance of holding pistons running:40mm;

Max load of punching: 60kN

Max load of holding: 10kN

Resolution of Erichsen value: 0.01mm;

Hydraulic oil: N46 hydraulic oil
