Induction melting process involves inducing swirly electrical currents in the metal, with a source as the induction coil which carries an alternating current. The swirly currents melt the charge by heating it up.

The improvising of the materials eventually makes them homogeneous and thereby clean them by churning out all the dissolved and bonded impurities. The vacuum levels are set to be in the range of 10-1 to 10-4 mbar during this type of refining phase and requires precise control for melting.

Compared to other kinds, the melting process is quite easier in VIM, attributing the independent control of time, pressure, temperature, and transport through melt stirring. In the process of vacuum induction melting, it is important to have flexibility in controlling the alloy composition by sampling and mixing up of the required alloys.

Some important usage of vacuum induction melting are:

# Refining of finest impurities from metals and alloys

# Electrodes for remelting

# Investment casting

# Making casts of aircraft engine components
