8. Deviation to the rule

8.1 Modification of given times

The specified times may be prolonged or
shortened individually, if required.
Info
The performance of the heating
might decrease slightly after 1000
operating hours. By prolonging the
heating times by 5-10 seconds opti-

8.2 Plasticizing of blanks with unknown heating times

Create a heating programme corre-
sponding to the foil thickness in ques-
tion with a sufficient prolongation of
the heating time (see point 7.1). Start
the programme (see point 7.2). You
may test the plasticization degree of the
blank by means of an edgeless metal
instrument (e. g. wax knife).
Info
The complete deformability of the
blank can only be tested at the
edges, as that is where warmth
will leak through the metal con-

8.3 Abort/termination of programme

It is possible to abort/terminate all
actions of the Drufosmart by pushing

be attained again. The given times
are average times and designed
for general use. In case of extreme
undercut areas or very high models
a prolongation of the heating time
can optimise the results.
tacts and the necessary flexibility
will be attained at last!
After the blank has attained the neces-
sary flexibility initiate the thermoform-
ing process (see point 7.3). The cooling
time can be terminated at any time by
pushing the heating handle (5). How-
ever, a sufficient cooling down time is to
be observed, as warm foils may deform
during removing them from the model
and therefore lead to bad resp. useless
thermoforming results.
the turnable pressure controller (44) for
at least 3 seconds.

9 Optional additional functions

9.1 Fabrication of cast form parts

With the K-7 insert it is possible to
thermoform up to 7 resin bases for the
crown and bridge technique at the same
time. Fix the single dies by means of a
flexible blocking out material (e. g. Fillin)
in the holes of the K-7 insert.
All further working steps as described
from point 7.1 on.
