Description of the machine
The Shannon HRT bending machine is a rapidly convertible
machine for the production of large series of items with
multiple bends for the plastic sheet processing industry.
The machine has two adjustable heating elements as
standard. The temperature of which can be adjusted
independently by electronic controls.
The filaments of the heating elements on the working
surface are adjustable in height.
The workpiece can be heated from one side and it is
possible to bend sheet up to 5 mm thick.
The working surface is made of scratch-resistant solid
core material with which the space between the zones to
be heated can be filled to support the plastic sheet.
When heated, thermoplastics become so flexible that they
can be shaped. When a plastic sheet is heated to its
softening point in a narrow zone, if can be bent to any angle
desired.
The bending radius is determined by the width of the heated
zone. The zone is determined by the thickness of the
material, the type of heating element and the distance
between the plastic and the filament.
Every plastic has its specific softening point. By coordinating
the temperature, heated zone and the heating time all kinds
of thermoplastic can be processed.

Safety
To ensure sfety when using the machine you should erad
this User’s guide carefully and follow the safety instructions
closely.
Attention!
The machine contains parts which are hot. Touching
them will cause burns.
Allow hot parts to cool sufficiently (at least 10 minutes)
before touching them.
Never touch the filaments or the reflectors when the
machine is in operation.
Always wear close fitting clothing.
Be particularly careful of sleeves and always tie back long
hair.
The machine may only be used for heating narrow
zones in flat plastic sheets. Any other use could lead to
very hazardous situations or cause damage to the machine!
The plastic sheets that have to be bent may never be
thicker than 5 mm.
Before commissioning and servicing, always check the
connection cable and plug for defects.
When servicing, switch off the machine and remove the
plug from the socket.
Only switch on those heating elements which are
needed.
Never leave the machine unattended without switching
it off.

Installation
5.1 ASSEMBLY
1. Place the machine on a level floor with sufficient space around and
above the machine.
2. Ensure that there is adequate ventilation and lighting at the workplace.
3. Avoid draughts, in order to prevent uneven heating.
5.2 CONNECTING MAIN VOLTAGE
1. Check that all switched of the control units are in the 0-position
(Switch H).
2. Put the plug into the socket

Operation
6.1 PREPARATION
1. Clear the working surface.
2. Check that all the heating elements are connected to the control units.
3. Check that no scraps of material remain in the reflectors.
6.2 SWITCHING ON HEATING ELEMENTS
Each heating element can be switched on and controlled individually.
Switch on the control unit with switch H.
6.3 SETTING TEMPERATURE
The temperature of the filament can be set using the temperature control.
1. When turning on the on/off switch, the display will show the value that
was last saved (keeping the machine on a certain value for >20
seconds will make it remember this value).
2. Press the right button (arrow up) to increase the value, up to 99
(keeping this pressed in will make the value cycle much faster)
3. Press the left button (arrow down) to decrease the value, down to 00
(keeping this pressed in will make the value cycle much faster)
4. Press both buttons at the same time to go directly to 00. Doing this also
resets the machine.

Adjustment
7.1 SAFETY PRECAUTIONS
Always take the following safety precautions before adjusting the heating
elements:
1. Switch off the heating elements one by one (Switch L).
2. Clear the working surface.
3. Allow the heating elements to cool for at least 10 minutes.
7.2 HEATING ELEMENT
1. Remove the strips of solid core material next to the
heating element to be adjusted by loosening the two
socket head screws (Use socket screw key no. 5).
2. Loosen the socket head screws in the supporting prongs
on the left and right of the heating element one half turn.

heating element one half turn (use socket screw key no.
3).
4. Take the heating element with both hands close to the
supporting prongs on the left and right, and slide it into the
desired position.
5. Hold the heating element parallel to the front of the
machine and the supporting prongs. This prevents the
notched nuts in the X-profiles from binding.
6. Hand tighten the socket head screws, starting in the
supporting prongs and then in the centre.
7. Position the other profiles in the same way if necessary.
8. Fill up the space between the heating elements as far as possible with
solid core strips and hand tighten them. First slide the notched nuts into
the aluminium X-profiles, roughly level with the holes and then lay the
solid core strip on top.
9. Switch on the machine again as in section 6.
7.3 FILAMENT HEIGHT
1. Adjust the height of the filament using the knurled nut.
These can be reached from the sides. Make sure that
the filament height is the same on both sides.
2. Start up the machine again as in Section 11.

7.4 STOP
1. Loosen both the handles on the stop one half turn.
2. Slide the stop into the desired position.
3. Hold the guide parallel to the front of the machine. This
stops the clamping blocks from binding.
4. Tighten the handles.
5. Pull the handle upwards against the spring pressure, and
turn it outwards.

Tensioning and changing filament
9.1 SAFETY PRECAUTIONS
Before tensioning and changing filament always take the following safety
precautions.
1. Clear the working surface.
2. Switch off the control units one at a
time (Switch H).
3. Allow the heating elements to cool for
at least 10 minutes.
9.2 TENSIONING
1. Turn the filament to the lowest
position
2. Hold the end of the wire on the right with pliers, and undo
the screw in the wire pin.
(Use socket screw key No. 1½).
3. Pull the wire taut with pliers and tension the spring.
4. Tighten the socket head screw firmly again.
5. Cut off the end of the filament. Always leave 8-10 mm projecting in
order to be able to tension the filament again.
Attention! The end of the filament is sharp.

9.3 CHANGING THE FILAMENT
1. Turn the filament to the lowest position.
2. Unscrew the socket head screw in the wire pon on the
right. (Use socket screw key No. 1½).
3. On the left side, slide the expanding pin with the spring
out of the pin block.

5. Unscrew the expanding pin from the connection screw
(incl. connection wire).
6. Remove the filament from the expanding pin and the wire pin.
7. Slide a new filament into the expanding pin, and make
sure that the eye is pulled well into the pin.
8. Screw the expanding pin onto the connection wire (incl.
connection wire), and attach firmly.
