The principles of induction heating


The induction principle is optimal for melting metals. The crucible is positioned in the core of the induction coil so that a steady temperature can directly be generated in the melting material. Because of the strong magnetic field the liquid metal will be mixed intensively. The so called inductive bath movement makes the production of pre-alloys unnecessary


Principle of our Vacuum Pressure Casting Machines

INDUTHERM machines are suitable to melt and cast metals of high melting temperature.

According to the model, they can also melt steel. Also alloys or metal with a low melting point such as Aluminum may be easily processed with them.

The basic idea of the INDUTHERM vacuum/pressure casting machines is to close the cover and start the heating up once the machine has been filled with casting material.

The temperature may be selected by hand or it may be programmed depending on the model you are working with.

The material is molten under protective gas to avoid oxidation. The melting procedure may be observed through the looking glass. The crucible is placed centrally in the upper part of the air-tight closed

aluminum case in the core of the induction spool

In the meantime the flask with the heated up casting form is placed in the lower part of the aluminum case (vacuum chamber).
The vacuum chamber is tilted and docked under the crucible. For the casting process the crucible is set under pressure and the flask under vacuum.
The difference of pressure leads the liquid metal into the finest ramification of the form.

The vacuum avoids bubbles and porosity. Afterwards the vacuum chamber is opened and the flask may be removed.

Most machines are equipped with a flask lift which pushes the flask towards the caster. This simplifies the removal of the flask.
