These are hydraulic Press with different configuration depending on customer demand.
Depending on the configuration, the machine can be used for the production of dishheads, shipbuilding or general metal fabrication
Thanks to the design of the machines frame, the high strenght of the machine is reflected in the accurancy of the finished products
This press model is used for:
• Flattening large thickness and sized plates
• Straightening forged bars
• Straightening long electro-welded structures
The main characteristic of these machines is that the pressing unit, instead of having a fixed position, is mounted on a special carriage that allows for a longitudinal movement on the bottom bench. Even the uprights moves longitudinally along the entire length of the lower bench which remains fixed.
The movement of the pillar is done with the use of epicyclic reduction gears and a hydraulic motor that allow the pillar to slide along the rails.
To prevent deformation of the moving parts of the gantry, in the pressing phase the pillar unloads the force on special guides positioned horizontally on the mainbench.
This press model is used for:
• Forming complex parts
• Forming corrugated plates
The main characteristic of these machines is that the pressing group, instead of having a fixed position, is mounted on a special carriage that allows for a longitudinal movement.
This press model is used for:
• Producing dished ends
• Forming complex parts

Our presses consist of a low basement, two side uprights and the upper crossbar where the hydraulic cylinder and hydraulic control unit are found. For presses with low-tonnage push, the structure is a monolithic one.
The lower level is equipped with T slots for direct fixing both the moulds of the basement and the moulding, also equipped with T slots.
The metal structures of the basement, the uprights and the crossbar are made of plates of different electro-welded thicknesses, subjected to stress relieving heat treatment to remove stress due to welding and sandblasting treatment with pre-coating.
Hydraulic control unit consisting of: motor pump unit, electro valves, pressure relief valves which guarantee overload protection. The unit is positioned above the upper crossbar and is connected directly by means of special pre-filled valves to the hydraulic cylinder.
Siemens, ABB, Telemecanique, Moeller electrical system. It consists of a movable or flag console control panel, connected to the machine with low voltage and a general cabinet where there are installed all of the electrical components, as well as the machine control PLC SIEMENS S7.
Linear potentiometer mounted on the cylinder to read the position and manage the pressing programme.
SIEMENS KTP1200 PN independent control Touch Panel with 12” touch screen colour display. By changing pages it is possible to see on the display the position of the cylinder, to set its rate of descent and ascent, to set its working pressure and the diagnostic functions and the machine alarm. If there is the automatic MFB manipulator, it displays also all of the axis and the diagnostics.
Modem to remotely control the PLC in case of software changes and resolution of machine faults.
Air or water cooling system for hydraulic oil.
Hydraulic cylinder: the special design of the cylinder ensures rapid descent without the maximum use of electric power. The cylinder is equipped with 2 or 4 guide columns to prevent rotation of the rod and ensure maximum rigidity during its whole stroke.
Manipulators are hydraulic machines, auxiliary to fixed gantry presses and are used for forming dished ends.
The manipulator is synchronised with the movement of the press cylinder. These movements of the manipulator’s arms and carriage can be simultaneous or single.
Starting from flat plate disks, by carrying out a logical sequence of movements, they set up cycles for the execution of dished ends. This cycle is called the curved cycle.
The delivery capacity of the available manipulators ranges from 1,500kg to 24,000kg.
with the press controll system
of the construction design that grant perfect final results
Manipulator structure made of electro-welded steel plates, subjected to normalising heat treatment.
No. 2 motorised rolls mounted on the rear arms for disk rotation through the epicyclic reduction gears and hydraulic motor.
Front arm with idle wheel, adjustable upon request up to 75°
The cylinders are made of alloy steel and carbon steel with a chrome-plated rod and use seals from the primary brands.
Linear potentiometers mounted on each arm that allow electronic control of all manipulator axis.
