Hydraulic Universal Press with High Pressure Unit (30.000 kN)

The institute has a combined hydroforming and deep-drawing press with try-out functionality manufactured by DUNKES. A large dimensioned pressure accumulator allows a programmable force-path-time behaviour to realise the flexible try-out functionality. Three axial cylinders enable the hydroforming mode. For hydroforming of large sheet metal structures, a modular tool system with adapter and pressure supply plates is also available. The 3000 t DUNKES press can be booked on request with a medium-term planning horizon.

The possibilities of the flexible force-path-time curves, the high pressing force and not least the size of the press table supports the planned practical studies of body components and demonstrators.
