Induction heating is a cleaner, pollution-free, securer and highly efficient heating method for metal parts in extensive industry fields.

Place the workpiece inside the inductor (typically a red copper tube coil). When the induction heating power supply delivers high-frequency alternating current to the coil, it generates an alternating magnetic field around the conductor. This rapidly changing magnetic flux induces powerful eddy currents within any conductive material positioned inside the coil. These opposing-direction circular currents interact with the material's inherent electrical resistance, generating intense Joule heating effect. The resultant localized heat generation causes immediate temperature rise specifically within the workpiece itself, rather than through external thermal conduction.
