Safety instructions
The NAUTILUS®vacuum pressure casting device is
designed exclusively for casting dental alloys, with
the exception of titanium.
Any other use is deemed to be improper. We shall
not be liable for any damage resulting from improper
use.
ATTENTION! Casting titanium is not permitted! Risk
of personal injury and damage to the device!
Alloys containing beryllium produce strong oxides
during the melting process, will cause substantial
wear to the crucibles, and significant amounts of the
alloy will remain inside the crucible. ATTENTION!
Carcinogenic particles are released when beryllium
is processed! Cast and finish only while taking
suitable protective measures!
Aluminum and titanium (< 0.5 %) contained in non-
precious metal alloys without beryllium may produce
strong oxides, which could cause significant parts of
the melt to remain inside the crucible. Such alloys
can also not be cast with the NAUTILUS®.
The safety instructions must be adhered to in order
to prevent personal injury and damage to the
device. We shall not be held liable for any damage
arising from the failure to comply with the safety
instructions.

Device description
NAUTILUS®CC plus and NAUTILUS®T -
compact table casting devices with integrated cooling and user-friendly touch-
screen
Both devices use the established HF vacuum
pressure casting process with a split crucible and
come with integrated cooling as well as user-friendly
touchscreens.
Special emphasis was placed on dual redundancy
safety systems. A double closing sounds indicates
that both flaps are closed.
Both of the devices have an "eco-mode" to lower the
energy consumption when they are not in use for a
while; eco-mode is automatically activated after 3
minutes and stops 10 minutes after the touchscreen
lighting has turned off. During this time, the
NAUTILUS®only uses 10 W. To end the energy-
saving mode, simply tap on the touchscreen and the
device is ready for operation again within a few
seconds.
New software versions can be transferred using one
of the two USB interfaces on the back of the device.
NAUTILUS®CC plus and NAUTILUS®T casting
devices can therefore be updated.
NAUTILUS®CC plus comes with a pyrometer,
which not only measures the temperature of the
melt without direct contact but - in combination with
specially developed software - enables the casting
process to be automated to a large extent. This
allows for a reproducible quality of the casting
process, which can be documented and archived in
the form of casting logs via the USB interfaces. In
the event of malfunctions, it is also possible to call
up diagnostic protocols and send them to the BEGO
Service.
NAUTILUS®T comes with an integrated camera to
monitor the casting process. A casting video is
available for subsequent inspection/examination.
Determining the casting temperature for dental alloys with the NAUTILUS®CC
plus
The flowability of the melt and thus the casting
temperature are of decisive importance for the
quality of the cast object. The problems that may
result due to a melt that is too cold or too hot are
known in practice and described in the relevant liter-
ature and are therefore not discussed in detail here.
Dental alloys have the property of not having a fixed
melting point, but a melting interval. Within the
melting interval alloys occur in viscous as well as in
crystalline form.
The melting interval is easily identified by the
characteristic cusps in the melting and solidification
curve, which are the result of irregularities in the
temperature progression.
When an alloy is melted, the first cusp in the curve
is the so-called solidus, the second one is referred
to as liquidus; the liquidus specifies the point at
which the alloy is completely liquid. NAUTILUS®CC
plus uses this behavior in the temperature
progression by means of an analytical thermal
method.
To ensure optimal flowability of the melt in the dental
casting mould, the melt is heated beyond the
liquidus point. Depending on casting method and
alloy, a temperature increase between 100°C and
180°C has proven to be optimal in practice. Corre-

sponding recommendations for these casting
temperatures, which generally have been verified
by empirical tests, are given by the manufacturers of
alloys and casting equipment. With most casting
devices the accuracy for achieving the recom-
mended casting temperature through visual
assessment of the developing temperature still
depends on the individual skills of the user.
In contrast, the new NAUTILUS®CC plus casting
device uses an automatic measurement method to
determine the right time to cast, which facilitates an
exact determination of the casting temperature
within a very short period of time and even with only
small amounts of alloy. At the same time the light
information of the melt is evaluated by means of an
optical system and a so-called pyrometer with a
multichannel measuring system and converted into
temperature values. The melting process is
monitored on the basis of the data captured in this
way and casting can be triggered automatically (on
request also manually) after the alloy-specific
casting temperature is reached. The measuring
method applied is able to compensate for influences
due to fluctuations in the light emission of the melt,
such as those occurring when the oxide skin opens
during melting.
This innovative technology inside of the
NAUTILUS®CC plus has been used to determine
the perfect casting temperatures of BEGO alloys
and are stored in special casting programs for the
control system. Thanks to the new measuring
technique, it is now possible to determine the
casting temperatures very reliably and on a repro-
ducible basis. The standard values recommended
thus far for the casting temperatures of BEGO alloys
have consequently been adapted to the newly
defined values in some cases and are summarized
in the casting table of this operating manual.
If third party alloys are used with the NAUTILUS®
CC plus, the casting program of a BEGO alloy with
the closest match with regard to alloy composition
and alloy characteristics can be copied. Now only
the casting temperature and the name of the non-
BEGO alloy have to be adapted according to the
respective manufacturer's specifications. Users can
manually cast non-BEGO alloys, without specified
casting temperatures, according to their visual
impression and then utilize the displayed temper-
ature to create their own casting programs for
automatic operation with these alloys. A casting
program for a non-BEGO alloy in the program
memory of the NAUTILUS®CC plus can be set up
in just a few steps and is described in the operating
manual.
NOTE
Tip: Non-BEGO alloys should first be cast
manually with a pyrometer to check if the casting
temperature specified by the manufacturer is
correct.
