The flask/s are placed in the mixer
and the stirring unit is swivelled over them.

The weighed investment material is filled
into the stirring container.
The mixer is sealed with a plexiglass lid
which allows surveillance of all procedures.
Now the investment material is mixed
with the water under vacuum. Through
the opening of the filling taps the
underneath placed flasks are filled while
still under vacuum. This procedure and
simultaneous vibration allows flasks of
highest quality to be produced.
