142-40 Universal-Sheet Metal Testing Machine
The Universal Sheet Metal Testing Machine Model 142-40 with electro-hydraulic drive, fully automatic test sequence and switch off at specimen failure, max. drawing force of 400 kN.
Order number: 101-00480331
Application: This Testing Machine can be used not only to perform effortlessly, quickly and accurately all important and known deep drawing tests for ferrous and non-ferrous metals, but it is also designed for a large number of additional technological investigations like the ERICHSEN Cupping Test and the ERICHSEN Deep Drawing Cup Test on sheet and strip.
Relevant attributes are:
- Square Cup Test (40 x 40 mm),
- ERICHSEN Cupping Test
- Bore Expanding Test (KWI Test),
- Bore Expanding Test (ISO 16630),
- Deep Drawing Test with Blankholder
- Quick Release (for Earing Test),
- Deep Drawing Test with Preselected Punch Stroke,
- Deep Drawing Test at High Temperatures up to 550 °C,
- ERICHSEN Cupping Test for Lacquer and Paint in accordance with DIN ISO 1520,
- Stamping Lacquer Test and Deep Drawing Cup Test on Coil Coatings.
- Special Requirements on request.
The Testing Machine is driven electro-hydraulically.
The test sequence can be controlled automatically or manually, as desired.
A programmable logic controller is used to control the functions of the machine.
The testing machine is equipped with digital displays for indicating the sheet holder force, the drawing force. as well as the drawing punch stroke.
The triple-acting hydraulic system in conjunction with the general design results in the following cost saving simplifications:
- Blanking press in the test head
- Hydraulic cup ejector
- Fully-automatic test sequence with stop at specimen failure (as of 0.3 mm sheet thickness)
The Sheet Metal Testing Machine, Model 142-Basic, was developed for testing as a means for continuous production control using standardised and other established methods, but also for research into all aspects of testing of sheet metal for deep drawing by studying all that is relevant to sheet metal forming.
With the proportional valves options, the operator can control the 142-40 via the pc and the MES software. That 's also the best way to test traceability.

MES - Universal User Software
for control, adjustment, documentation and filing of measuring data of the sheet metal testing machine.
Software for recording of force displacement diagrams such as drawing force and blank holder force, stroke.
Creation of scripts (test sequences); presetting of freely selectable parameters such as drawing and blank holder force as well as drawing speed.
The measuring system integrated in the sheet metal testing machine is designed in modular system with analogue and digital inputs and outputs.
Hereby drawing force, blank holder force and stroke are acquired:
The data are exchanged with the PC via a USB connection.
This programme enables to create and evaluate test sequences for tests e.g. Erichsen deep-drawing cup test, bore expanding test, bulge test, Erichsen deep drawing test.
The scope of supply includes PC, VDU and printer.
Mes Soft : for sheet holder force data and drawing punch speed data the 142-40 requires two options :
- the Proportioning valve control of sheet holder force in the range between 0 kN and 400 kN- the Proportioning valve control of drawing punch speed in the range between 0 and 900 mm/min
