GENERAL INFORMATION

Your THERMOFORM is an extremely effective and handy device. It is
fitted with a low-voltage current heating element and a ring centred
transformer.
It is suitable for bending different types of synthetic materials, such as
Acryl (plexiglass, Perspex), polycarbonates (Lexan, Makralon) and PVC.
It is possible to bend sheets up to a maximum thickness of 8 millimetres.
The king sized top enables accurate placement of your work, the more
so in combination with the fixed and sliding rulers.
It is possible to bend very complicated shapes because the element is
not placed in the centre.
To prevent heat spreading to other parts of the device, a multiplex base
with a hard synthetic top was chosen. By applying a hollow cavity
around the heating element it is not likely that heat passes through to
other parts.
THE BENDING
By heating an area of the synthetic sheet (C)
just above the heating element (A) this area
will become plastic which enables you to
bend the sheet. It is important to bend the
sheet by stretching the plastic area (B) and
not by pressing it together.
Pressing causes a nasty rib in the created
angle.
After heating the sheet it should be taken off
the device and bended in such a manner
that the heated part is the outside bend.

Bending mould 500
Please make sure that the bended
sheet is left to cool in the requested
angle. To make accurate angles you
can use the specially designed
bending mould 500, completed with
a division into degrees.
For the bending of thick sheets (8
millimetres) it is advisible to heat the
sheets on both sides alternatively.
