The hydraulics of our offered presses are entirely based on BOSCH-REXROTH/Parker/HAWE components. The control cabinet exclusively uses (SIEMENS) components that are readily available in Germany. Safety technology, except for the light curtains, is entirely supplied by SICK. The system is operated by SIEMENS (S7 1500), including the 15” touchscreen monitor. The scope of delivery includes the SIEMENS remote maintenance unit SECOME Ethernet.

SPECIAL FEATURE: Our design with two press cylinders and the piston accumulator enables full performance with a main drive motor of just 90 kW.
