Pressure Adjustment; Start Of Programme - Dreve Drufomat scan Instrucciones De Trabajo

8.2 Pressure adjustment

The pressure of the Drufomat scan is
controlled digitally and can individually
be adapted to the thermoforming blank
in question between 29 and 87 psi infi-
nitely variable.
It is possible to control and to modify the
adjusted pressure and the actual pressure
during the thermoforming process via
the bar chart (g) of the display.

8.3 Start of programme

In order to start the selected pro-
gramme, put a blank that corresponds
to the entered barcode resp. program-
ming onto the plate reception (11) and
fix it by means of the tension ring (13).
The model can either be put onto the
nub plate of the F insert (6) or fixed by
taking out the nub plate and embedding
it into granules directly in the F insert.
Info
For an optimum adaptation of the
blank towards the model always
place the models in a way that the
anterior teeth are directed towards
the centre of the blank.
When using hard blanks it is recom-
mended to embed the models into
granules. Models that are placed
onto the nub plate should not
exceed a max. height of 23 mm.
The arrow to the left of the bar chart
shows the currently adjusted pressure.
The arrow can be moved along the bar
upwards and downwards with the +/-
keys (e/i). The pressure can also be mod-
ified during an ongoing thermoforming
process!
Info
The minimum operating pressure
is 29 psi (2 bars). If a thermoform-
ing process is interrupted before
having reached the 29 psi (2 bar)
mark (indication of bar chart (g)
in the display), the piston will be
ventilated and will return to its
original position.
Swivel the plate reception inwards at the
handle (10) just up to the mechanical
interlock in the centre of the unit. Also
swivel in the heating element (4) at the
corresponding handle (5) just up to the
mechanical interlock in the centre of the
unit. Close the ventilation valves of the
tension ring (12) and the F insert (6).
Press the OK key (f). There will be an
acoustic signal as confirmation for the
activation of the heating; the scanner
will turn off and the adjusted heating
time will elapse in the display. As safety
and identifying feature for an active
heating there will be four LED alight at
the front bottom edge of the housing.
