This document describes a duplex forming press machine that thermoforms solid surface materials like stone, acrylic, and polyester sheets using a vacuum membrane process. The machine has a 3000x1300mm heating oven and 950mm forming press that use heat and 0.5kg/cm2 of vacuum pressure to form materials in 3-5 minute cycles. Optional upgrades include improved vacuum circuits to reduce forming time and cooling coils to speed cooling for larger shapes. The machine precisely thermoforms materials for kitchens, bathrooms and interiors.

4. GENERAL FEATURES
HEATING OVEN + FORMING PRESS TYPE DUPLEX 30/13
Heating chamber useful dimension: 3000x1300 mm x 100 mm H
Loading from one 3000 mm press side
Oven drawer with 550 mm sliding height and 900 mm stroke
Forming press mounted on top of the oven.
Working platen height: 950 mm (Approx.)
In case of the piece to be pressed was a parallelepiped, the max.
dimension of the base (in width and length), cannot overpass the flange
frame inner dimension less two times the height of the piece itself.
In order to preserve the membrane lifetime and to avoid its
perpendicular elongation respect to the press platen it is important to
provide some filling shapes. Both the panels and the filling jigs cannot
have any sharp corners.

5. HEATING CHAMBER
Heating chamber useful dimension: 3000x1300 mm – 100 m Height.
Loading from one 3000 mm press side
Oven drawer with 550 mm sliding height and 900 mm stroke
Forming press mounted on top of the oven.
Working platen height: 950 mm (Approx.)
Max. Height of the piece to be processed, including the supporting jig: 500 mm
Structure made of tubular and welded iron sheets
Oven drawer with manual movement through wheels and guides, made
of tubular, shaped iron sheets and composite bearing surface in iron net.
Drawer locking system with tightening seal.
Thermal insulation of the heating chamber mad in rock wool (between
the oven and the forming press it is provided an hollow space in order to
avoid the heat transfer.
Heating system made by 2 finned electric resistances with big radiant
surface. One of them it is jacketed by a special holed metallic crown for
the hot air exit in order to grant the air distribution and its forced
recirculation.
Electric resistances installed power: 11 kW
Electric motor for air circulation:
0,25 kW
Max. temperature of the heating chamber: 200°C

Max thrust on the working platen: 38T
Heat resistant silicon membrane
ELECTRIC PLANT
Control board complete of:
general switch on/off
power signal lamp
emergency push-button
light selector for vacuum pump switching on/off
digital setting and visualization of the working temperature

7. OPTION ON DEMAND
OPTION ON DEMAND
Vacuum manual adjustment through mechanical valves
VACUUM CIRCUIT upgrading (extra charge):
The machine is equipped by a storage tank and an higher capacity pump,
allowing the membrane depressure time reduction and therefore the
composite material shaping time (It is normally used to process shape over
500 mm height by the suitable membrane)
COLLING DOWN CIRCUIT (extra charge):
The machine is equipped by a cooling down coil that is contact to the
aluminium plate inside which are made the vacuum channelling and the
silicon seal tightening seat (cooling down system excluded).
It is used to keep cool the composite supporting shapes and reduce the
cooling down time.

8. UPGRADING MADE ON A STANDARD MACHINE
We achieved the composite heating temperature uniformity, improving the heating
chamber efficiency, installing finned electric resistances with big radiant surface.
One of them it is jacketed by a special holed metallic crown for the hot air exit in
order to grant the air distribution and its forced recirculation.
We removed the heat dispersion inside the heating chamber, installing a double
mechanical locking system for the drawer, with a tightening silicon seal.
Furthermore we upgraded the thermal insulation providing an hollow space in order
to avoid the heat transfer.
