THE INDUCTION HEATING PRINCIPLE
The induction heating principle consists in placing a metal within the influence of an oscillating magnetic field at
a determined frequency such as the one generated by an induction coil. In the centrifugal casting machine mod.
MODULAR 6 the frequency is 80 KHz.
All metals have induced within them “eddy currents” and the metal electrical resistance to these
currents provokes a temperature rise and eventual melting.
The “eddy currents” form a molecular movement in the melting metal and give a thermic homogeneity to the
melting mass as depicted by the pictures.
The induction heating results to be the best thermic energy source for melting and offers the following
advantages:
– unchanged metallurgical characteristics: elasticity, homogeneity, and ductility
– silent and clean working conditions
– higher purity of the molten metal
– great productivity
– high melting temperatures without jeopardizing the machine components

ELECTRONIC CENTRIFUGAL CASTING MACHINE MODULAR 6
Centrifugal casting into flask
This electronic induction centrifugal casting machine has been built using the best technology and has a control
lay-out which is very operator-friendly.
It is designed for melting and casting the following alloys for dental use:
•
precious and non precious alloys for ceramic and resin
•
chrome cobalt molybdenum.
With the temperature controller it is possible to read and hold the casting temperature, obtaining the complete
fluidity of the metal which will be cast into the flask during centrifugation and reach the thinnest part of the model.
To facilitate the molten alloys to smoothly flow out of the crucible during spinning the MODULAR 6 fits a
sloping crucible holding plate which also ensures a complete and smooth flow of those alloys with a low specific
weight. The MODULAR 6 fits a universal flask cradle i.e. with an easy movement of the lever it is possible to
adjust the flask support and any sprue button of the flask will be easily centered with the crucible exit hole. This
universal cradle is particularly suitable when using the technique of the free expansion without metal casting rings
.Normally 5 standard flask sizes are used; the smallest flask size of 30 mm diam. must be inserted in the ceramic
container given as normal outfit and both of them must be put in the burn-out furnace. This ceramic container will
maintain a constant temperature of the small flask during spinning.
ATTENTION: This machine must be only utilized for the intended purpose in accordance with the
seller’s instructions. Any other use is to be considered improper and consequently dangerous. The
manufacturer cannot be held liable for any damages caused for improper, wrong and unreasonable
uses.
ATTENTION: The use of non-genuine crucible which do not correspond to the parameters of the
machine final test will considerably shorten the life of the power generator.

INSTALLATION INSTRUCTIONS
THE ELECTRIC SYSTEM OF THE ROOM WHERE THE CASTING MACHINE
IS INSTALLED, MUST HAVE AN ELECTRICAL GROUND IN COMPLIANCE
WITH THE REGULATIONS IN FORCE.
ATTENTION
THE ROOM WHERE THE MACHINE IS INSTALLED MUST BE FREE FROM
SPRINKLINGS OF WATER, SAND BLASTING UNITS, ACID VAPOURS AND
DUST.
ATTENTION
IT IS FORBIDDEN TO REMOVE THE PANELS FROM THE MACHINE IF IT
HAS NOT BEEN PREVIOUSLY UNPLUGGED.
DANGER
INFLAMMABLE LIQUIDS AND GASES MUST BE PLACED DISTANT FROM
THE MACHINE DURING ITS USE

After having removed the machine from the packing material install it proceeding as follows:
1 Fill the tank with normal or better demineralized water up to 3 cm (1”) from the rim and close it with its cover.
The two hoses, coming from the pump filter, must be dipped into water down to the tank bottom.
As the machine is operated, the water pump will automatically start the water circulation. Should the water
circulation fail or be insufficient, the pressure switch placed on the water pump will not allow power output.
It is recommended to periodically check the flow of the circulating water, which must be 2 litres per minute
and it is measured at the machine water outlet by means of the special bottle included in the standard outfit.
2 Check the voltage of the mains. Any variation beyond 10% plus or minus than the voltage indicated by the
nameplate does not allow regular operation of the machine. Connect the line cord to the singlephase 230 V
mains with regular grounding. A possible automatic safety breaker must have a 0,5 A differential switch.
3 IMPORTANT: the machine is electrically controlled by an overload safety switch in compliance with the CE
regulations which cuts off power in case of current overloads due to faults in the machine or to current surges
of the mains.
This switch is located up on the left of the front side of the machine and it is indicated with A2 in the drawing
table A of the trouble shooting manual.
Should it cut off, unplug the machine, remove the front panel and set it again on the ON position. Fit the front
panel, switch on the machine and should the overload switch remain on the ON position it means the cutting
off was due to any occasional cause, should it cut off again it is necessary to ask for the technical service and
to look for the cause.
With the due precautions the machine can be switched ON by an authorized operator with the removed
panel.
IMPORTANT NOTICE
For prevent the crucible holding plate Afrom breaking,
which slides against the flask when spinning is started,
place the ring Bin such a way to stop the travel of the
crucible holding plate abt 2 mm from the flask.
The ring B must be positioned in relation to the
length of the flask. Do not place it too distant from
the flask otherwise the crucible exit nozzle will not
reach the sprue button of the flask and the metal
might spill during spinning.
When using small flasks with 48-50 mm ø the small plate
Cis placed on the flask support to enable the sprue
button of the flask to be easily centered with the crucible
exit hole.

A MAIN SWITCH: it switches ON and OFF the machine.
C GREEN LED: when illuminated it shows that the heating power is available. This happens if the water
flow is two litres per minute, the induction coil is surrounding the crucible and the machine cover is
closed.
D ORANGE LED: when illuminated it indicates that the generator does not supply heating power because
water temperature has exceeded 60 °C or because the generator itself is faulty.
E POTENTIOMETER FOR HEATING POWER REGULATION AND CENTRIFUGE STOP: power
output is stepless. After each casting cycle bring the potentiometer to 0 to stop the centrifuge and have the
machine ready for the next cycle.
F TEMPERATURE CONTROLLER WITH DIGITAL DISPLAY (°C): it displays the actual
temperature of the metal being melted and the chosen casting temperature which is held by controlling the
power output.
