Manufacturing Partner:

Universal Sheet Metal Testing Machine, Model 142-20-Basic comes with an electro-hydraulic drive, max. drawing force 200 kN and holder force of max.100 kN. It is ideal for testing sheets and strips and has a fully automatic test sequence and switch off at specimen failure.

It consists of a solid housing made of high-strength steel into which the test aggregate (test cylinder with work piston, sheet holder plate and die) are integrated.

  • 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.
  • The tools required for each individual test can be changed quickly.

Possible Tests:

  • ERICHSEN Cupping Test
  • Deep Draw Cup test (at temperatures up to 550 °C)
  • Deep Drawing Test with Blank Holder Quick Release (for Earing Test)
  • Deep Drawing Test with Preselected Punch Stroke
  • Square Cup Test
  • Bore Expanding Test
  • Nakajima Test for Determination of Forming Limit Curves
  • ERICHSEN Cupping Test for Lacquer and Paint
  • Stamping Lacquer Test and Deep Drawing Cup Test on Coil Coatings
