An induction heating system consists of an induction power supply for converting line power to an alternating current and delivering it to a workhead, and a work coil for generating an electromagnetic field within the coil. The work piece is positioned in the coil such that this field induces a current in the work piece, which in turn produces heat.
The water-cooled coil is positioned around or bordering the work piece. It does not contact the work piece, and the heat is only produced by the induced current transmitted through the work piece. The material used to make the work piece can be a metal such as copper, aluminum, steel, or brass. It can also be a semiconductor such as graphite, carbon or silicon carbide.
Key Benefits of Induction are:
- Efficient and quick heating
- Accurate, repeatable heating
- Safe heating as there is no flame
- Prolonged life of fixturing due to accurate heating
