The hydraulics of the presses we offer are configured exclusively with BOSCH-REXROTH/Parker/HAWE components. Only (SIEMENS) components that are readily available in Germany are used in the control cabinet. Safety technology is supplied entirely by SICK, except for the light barriers.

The control system is provided by SIEMENS (S7 1500), including the 15-inch touchscreen monitor. The delivery also includes the SIEMENS remote maintenance unit SECOME Ethernet.

SPECIAL FEATURE: Our design with two press cylinders and the piston accumulator allows full performance to be achieved with a main motor of just 90 kW.
