The hydraulics of the presses we offer are completely based on BOSCH-REXROTH/Parker/HAWE components. In the switch cabinet only components are used (SIEMENS) which are easily available in Germany. The safety technology comes completely from SICK except for the light barriers.
The control system is supplied by SIEMENS. ( S 7 1500 ) as well as the touch screen monitor with 15 inch. The SIEMENS remote maintenance unit SECOME -Ethernet is included in the scope of delivery.

SPECIAL FEATURE: the design chosen by us with two press cylinders and the piston accumulator make it possible to supply the full power with a main motor of 90 kW.
