End Face Induction Heating CoilScrew top small parts topside heating is usually heated by the way of end face induction heating sensor, and the work piece must be rotated. Track links end surface is heated once, it also uses this principle, the work piece is not rotated about shaking to obtain uniform heating. Track links end surface scanning heating, also with this principle, but under the pressure of both sides of the tube to the right and left side of the work piece, and an increase of the effective loop length.
