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)
