Production of special presses

The work of designing and manufacturing special presses is intended to meet the various production needs of customers, the machines manufactured are distinguished by high rigidity of the structure, maximum flexibility of control and precision.

This range of presses includes:

Presses used in the high power transformer sector

We have produced numerous presses for some of the industry leaders, introducing a significant change in the compacting process, precisely by moving from an almost manual and “not numerically controlled” compression process (carried out with screw/nut press systems) to a numerically controlled system in which the pressure exerted by the press ensures parallelism between the two end surfaces and a force that is constantly controlled and displayed at every stage of its advancement.

Our presses make it possible to have an automated tracking of the cycle performed associated with the serial number of the workpieces.

Considerable attention has been paid to operator safety and optimisation of work cycles (which have been made faster thanks to the introduction of innovative technology using special self-propelled structures).

Presses for clamping and unclamping

The horizontal column presses used to clamp and unclamp wheels, flywheels, gears, impellers etc. on shafts and/or railway axles are equipped with two height-adjustable supports to hold the piece during machining and a graphic recorder of the forces exerted.

Swan neck presses

The hydraulic swan-neck presses (single upright presses) are presses used to carry out moulding and straightening operations, they have a limited footprint, are very versatile and can be used for various applications.
