CONSTRUCTIVE FEATURES
Structure made of welded and normalized steel beams.

The constructive design guarantees the highest level of resistance and rigidity in each pressing phase for obtaining the best gluing quality of the pressed product.

The components are all machined on cnc machining centres to grant the

three-dimensional verticality of the structure and then assembled on precision templates.

HYDRAULIC UNIT
It consists of a double pump and related electric motor dipped in hydraulic oil for a longer life and lower levels of noise.

The first pump has a high capacity and low pressure for a fast platen closing with exchange valve to switch quickly to the second high pressure pump.

To ease check and maintenance operations all the groups are in a single unit: high and low pressure pump, oil filter, control and safety valves.

The cylinders are stress relieving treated to eliminate the mechanical stress created during welding. The alloyed steel rod is chromed with a thick layer and then rectified. Assembling is carried out with particular care and constant control of the dimensional tolerances.

High resistance gaskets to grant a perfect and long lasting seal over time.

The large dimensions special flanges grant a perfect guide of the rod even at its maximum stroke.

FLATNESS CONTROL
The press is equipped with a mechanical system with 2 couples of racks,

pinions and torsion bars for a perfect longitudinal and transversal control of the mobile platen movement.

It is furthermore provided with adjustable side guides, for the sliding of the platen.

CE safety regulations for sergiani GS

Special care and attention has been paid to operator safety, equipping the press with the following serial devices:

– Perimeter safety cable to block the platen stroke in case of emergency, by anywhere around the press. The cable ends on a micro-switch with manual reset. The cable is external to the press frame for an easy access.

– Safety timed double operating non-release hold push button

– Push button for emergency stop of the press

– Main switch prearranged for locking with padlock

All parts that could create a danger are marked with accident prevention signalisation according to EC standards, or protected with safety nets.

SERGIANI GS 6/90 25-13 PA
– 6 CYLINDERS D.70 MM – 90 TON.
– PLATENS FROM 2500X1300MM
– Assembled platens features
– 90?C water ? 120?C oil maximum working temperature
– standard opening 400 mm

ASSEMBLED COIL PLATENS
Assembled heating platens have the following features:

– Panel for thermal insulation between the heating platen and the press frame;
– 2 thick, polished and calibrated steel sheets, an upper one and a lower one, that cover and hold the coil;
– The heating coil is made of tubular steel welded on proper template. Filling tubulars are welded in the gaps of the coil to guarantee the resistance uniformity in every point of the platen. Each coil is controlled and tested to verify the perfect tightness of the heating fluid;
– Upper platen covered with an aluminium sheet, mechanically positioned under a heat procedure, for the steel surface protection and a perfect finish of the pressed surface;

Specific working pressure of the platen up to 5 kg/cm?. The heating platens are fixed to the press platens through proper tie-rods to allow the thermal expansion and to ease the maintenance and replacement interventions.

DIGITAL CONTROL PANEL
OPERATOR PANEL with display and keyboard
Siemens control panel with 7” colour touch-screen.
The system is equipped with a dedicated software that makes the use of the press easy and immediate.
The following parameters can be programmed with the possibility of recall and modify them:
– Automatic adjustment of hydraulic pressure according to the panels size and the required specific pressure. The system automatically adjusts the cylinders pressure and the operator does not need to make any calculations based on graphs or tables. Possibility to save up to 100 working recipes (e.g. temperature, specific pressure, timer for pressing and panels dimensions);
– Direct setting of cylinders hydraulic pressure with digital control based on the chart. The system can be used as alternative to the automatic pressure regulation for those who want to work with the traditional method;
– Electronic adjustment of the pressing time (which can be excluded);
– Electronic control of platens temperature (only for BO and BA version);
– Possibility to automatically partialize the boiler electricity consumption when the temperature set has been reached, only for presses with electric boiler superior to 18kW;
– Possibility to automatically exclude a row of pressing pistons, depending on the dimension of the elements to be pressed (standard function on presses with 8 – 10 cylinders, optional function on presses equipped with electric exclusion);
– Programming of the boiler starting time for every day of the week (only for BO and BA version);
Furthermore the following functions are available:
– Automatic pressure reset based on the material settlement;
– Complete diagnostic and failures reporting with messages on the display. The system controls the main components of the press and reports the malfunctions that may occur for a quick and easy trouble shooting and working out.

VERSION WITH ELECTRIC BOILER FOR DIATHERMAL OIL
Max. working temperature is 120?C.
The press is provided with an installation including:
– Battery of electric resistors, composed by an independent unit, for the diathermic oil heating with protection against short-circuits. The resistors and the body of the boiler are made of steel with galvanic treatment for superficial protection. The body of the boiler is covered with thermal insulation;
– Pump and oil circulation system with safety device to protect the resistors in case of shut down of the pump;
– Electronic control of the circulation system according to different environmental conditions for a longer life of resistors;
– Expansion tank with bleed air valves and safety valves. The expansion tank and the pipes are made with specific materials for heating installations selected among the best brands;
– First COMPLETE filling of diathermic oil included in the supply;
– Electronic and electromechanical power drives;
– Electronic control of the circulation system according to different environmental conditions, for protection and longer life of resistors;
