Description of the machine
The Shannon HRT/D plastic bending machine is a rapidly
convertible machine for the production of very large series of
items with multiple bends for the plastic sheet processing
industry.
The machine has three 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 work piece can be heated from one side and it is
possible to bend sheet up to 8 mm thick.
This machine is equipped with an easily adjustable and
controllable transport- and feed system. Multiple feed belts
transport the work piece over the heating elements from
the right to the left of the working surface. This way all the
sheets are equally heated and the full table length is in use.
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 co-ordinating
the temperature, heated zone and heating time all kinds of
thermoplastic can be processed.

Safety instructions
SAFETY INSTRUCTIONS:
To ensure safety when using the machine you should read 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.
Never leave objects on the working surface.
The machine may only be used for heating narrow zones in flat
plastic sheet.
Any other use could lead to very hazardous situations or cause
damage to the machine!
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.
Never introduce objects or material into the machine from the
rear.
Never leave the machine unattended without switching it off.

Installation
4.1 ASSEMBLY
1. Remove packaging
2. Place the machine on a level floor with sufficient space around and above the machine.
3. Level the working surface of the machine, using shims under the feet if necessary.
4. Ensure there is adequate ventilation and lighting at the workplace.
5. Avoid draughts, in order to prevent uneven heating.
When moving the machine with a forklift truck ensure that the machine is supported
right in the centre.
Also use sufficiently long prongs on the forklift truck.
4.2 CONNECTING POWER CABLE
1. Check that the rating of the electrical system is adequate (see technical data).
2. Plug in the machine.

Operation
5.1 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.
4. Switch off all the control units (position "").
5. Turn on the main switch (position I).
5.2 SWITCHING ON HEATING
ELEMENTS
Each heating element can be switched on and controlled
individually.
1. Switch on control unit with switch H.
5.3 SETTING THE 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.

Transport system:
Before using the transport system, first turn the speed regulator[5] all
the way to the left. To activate the transport system, switch the green
button[4] so that it lights up. Then, turn the speed regulator[5] to
regulate the speed. On the right you’ll find a table which gives an
indication on how fast the track goes from 1 end of the machine to the
other, on each rotation of the knob.
Feeding system:
1. Press the left green button[2] so that it lights up. The
control system of the feeding system is now activated.
2. There are three numbers now on the display ranked
from top to bottom as:
a. [7] The number of cycles that the machine will
operate (the number of plastic sheets that are
loaded)
b. [8] The time in seconds that the pusher is
reloading a new piece of plastic.
c. [9] The time in seconds that the feeding system
is pushing a new piece of plastic.
3. For first time usage, set all the values on 10:
a. Swap between values by using the ▼/▲buttons.
b. Increase or decrease the value by using +/-.
c. Cancel the value by using he “ESC” button.
d. Confirm the value by using the “OK” button.
4. Press the round red button[1] to stop the machine
5. Press the green round button[3] to active the pneumatics. The feeding system will
begin working now.
6. The feeding system can be fine-tuned in the following ways:
a. If the system stops too fast, increase the cycle number by increasing the top
value in the display.
b. If the reloading time is too long, decrease the second value on the display.
c. If the pushing time is too long, decrease the third value on the display.

Adjustment
6.1 SAFETY MEASURES
Always take the following safety measures before adjusting the heating elements:
1. Switch off the heating elements one at a time (Switch H, page 10).
2. Clear the working surface.
3. Allow the heating elements to cool for at least 10 minutes.
6.2 LOWER 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.

3. Loosen the socket head screw in the centre of the 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.
Hold the heating element parallel to the front of the machine and
the supporting prongs. This prevents the notched nuts in the
aluminium X-profiles from binding.
5. Hand tighten the socket head screws, starting in the supporting
prongs and then in the centre.
6. Position the other profiles in the same way if necessary.
7. 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-
profile roughly level with the holes and then lay the solid core strip on top.
8. Switch on the machine again as in Section 5.

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