2. PRODUCTION CYCLE
FOR MDF BENDED PANELS
WITH 3D PVC COVERING

3. 1. GLUE SPREADING
The first phase is to spread the glue on the MDF boards,
normally 3 mm thick sheets
This is done with a normal 2-roller glue spreader.
The width of the glue spreader depends on the MFD board
width.
ORMAMACCHINE can deliver 2-roller glue spreaders from
300 to 1600 mm

4. 2. DISC CONVEYOR
A disc conveyor can be positioned after the glue spreader
and it is recommended in case of big MDF boards or in
case of gluing together or continuously several MDF
boards.

5. 3. BENDING PRESS
The glued pieces are then loaded into a press which is equipped with a jig for
giving the desired shape (curve/radius) to the final board. The jig is normally
made of multiply wood and it is covered on its surfaces by aluminium sheets,
acting as positive and negative pole in case of using high frequency. Some
customers just use the press as a cold press, but the curing times are
extremely long.

6. 4. HIGH FREQUENCY GENERATOR
Due to the big amount of glue (several MDF layers and each one of them glued) it is
recommended to use high frequency in order to shorten the curing time, which
otherwise would be very long.
When using high frequency there are actually two cycles:
1st - high frequency glue curing time together with the operation to reduce the
moisture to the normal degree
2nd - the wood is stabilized to its new shape
Technically it is said that the wood memory is killed and the working piece cannot return
to its original shape.
The high frequency is transmitted by the generator to the jig surfaces by means of metal
sheets.

7. 5. CNC ROUTER
The new bended MDF boards must be worked with CNC router before being sprayed
with glue for the 3D foil vacuum glueing process in a membrane press.
6. SPRAY GUN GLUEING
The MDF boards worked with CNC router are then glued with a spray gun. Normally this
is a manual process with spray gun and a protection cabin, some customers have an
automatic line because of the high production they have. The glue is polyurethane
water based and must be sprayed on the board surface and corners. This glue will then
dry and react with the heat in the membrane press. In case of a long time before
processing the board in the membrane press (glue open time) it is required a hardener.

8. 7. PVC FOIL
PVC is a plastic 3-D thermo formable film. Pvc films are supplied as decorative surfacing
for lamination to profile milled MDF boards and ensure processing in thermoforming
(membrane and vacuum) presses and application for interior furniture.
PVC foil rolls are available in all colours, design and finishing ( i.e. satin, nature, gloss,
highgloss) and for this process they are normally delivered with a thickness between 0.4
and 0.5 mm and a max. width of 1400 /1450 mm.

9. 8. MEMBRANE PRESS
The last process is the membrane pressing. For this type of working ORMAMACCHINE
offers the AIR/SYSTEM ECO press type, a flexible vacuum and membrane press
which can be used for various purposes. This machine can carry on 3D foil pressing
without membrane, 3D foil pressing with membrane, single side veneering on
shaped panels, manufacturing of multy-ply shaped panels thanks to a higher flange. A
press particularly suitable for medium companies, craft laboratories, test rooms and
wherever versatility is requested. The press has been completed with a manual infeed /
outfeed tray in order to make easier loading and unloading of the working pieces.
In case of curved MDF panels the press can be provided with a system of modular
multiple flanges (no. 3 flanges, each one 40 mm high) which can be mounted and
demounted on the movable tray in order to reach a total vacuum chamber height of 180
mm which allows to work with working pieces with a max. height of 175 mm
