English
Vestacast is a compact, easy to operate induction casting machine for melting and casting all dental
alloys with the exception of titanium and titanium alloys.
It is ideal for use in smaller commercial laboratories as well as in private practice laboratories it can be
operated manually and has a variable heating control. On the other hand, large laboratories can make
good use of it too, as its cooling system and capacity supports continuous operation.
The machine operates according to the principle of energy transfer used in transformers and known as
induction.
After creating a high-frequency magnetic field, a secondary current is produced by induction flows on the
surface of the metal to be melted and this current is transformed into heat which then melts the metal.
The eddying currents created in the molten metal ensure that the metal is thoroughly mixed.
The subsequent centrifugal casting into an investment also helps to produce a homogeneous mould.
The main advantages of Vestacast induction casting machine are:
high melting capacity with low energy consumption
•
homogeneous melting and casting
•
reduction in the amount of finishing required
•
easy operation
•
compactness
•
easy maintenance.
•
The main part of the machine is a high-frequency generator which is encased in a sheet-steel housing.
The generator meets the requirements for electromagnetic tolerance. The high-frequency generator
produces a 110 kHz electromagnetic field which heats and mixes the molten metal to a very
homogeneous consistency. The induction coil (Fig. 2-4) is water-cooled and protected against
overheating.
The centrifugal arm (Fig. 2) in the casting chamber holds the crucible and mould ring. The centrifugal
•
arm has a counterweight to ensure smooth, quiet running.
The induction coil heating element in the lower section of the chamber rises automatically to encircle
•
the crucible when the program is started. After the heating phase, when the Casting button is
pressed, the induction coil is lowered and the casting cycle commences.
The melting process can be observed through a protective glass which is integrated in the cover.
