Universal Sheet Metal Testing Machine - Erichsen 145-100

Universal Sheet Metal Testing Machine – Erichsen 145-100

Universal Sheet Metal Testing Machine, Model 145-100 comes with an electro-hydraulic drive, max.  drawing force 1000 kN. The blank holder force can be pre-set to a  max. of 1000 kN. Control of sheet holder force and drawing punch speed, for testing sheets and strips is possible. The machine has a fully automatic test sequence and automatic switch off at specimen failure.

  • The operator’s controls are well arranged on the control panel.
  • Electro-hydraulically driven operation.
  • Automatic or manual control of test sequence.
  • A programmable logic controller is used to control the functions of the machine.
  • Sheet holder force, the drawing force, drawing punch stroke is digitally displayed.
  • Triple-acting hydraulic system.
  • Cylinder head with bayonet lock.
  • Infinitely variable drawing speed.
  • Cardanic drawing die retention.
