Apparatus and method for inductive heating of a material located in a channel. In one embodiment, the heating assembly comprises an interior coil, an exterior sheath inductively coupled to the coil, a dielectric material disposed between the coil and sheath, and a conductor for supplying a signal to the coil to generate the magnetic flux for inductive heating of the sheath. The heating assembly is disposed in the material in the channel, and the magnetic flux generated by the coil may also inductively couple to the material in the channel. The material may be heated from a nonflowable to a flowable state, such as heating a metal or polymer plug formed in a melt channel of a molding apparatus.
