Rf Heating

Low and high frequency heating have different purposes and uses. The frequency of the rf (radio frequency) generator is one factor that determines the depth of heat penetration in a workpiece. In a large piece of metal, the heating effect is most intense near the induction coil. In order to develop sufficient heating deep inside a large workpiece, low to medium frequencies are used.

In order to heat small parts, higher frequencies are necessary. Smaller induction coils using alternating currents are needed. In surface hardening, high frequency develops heating only in the "skin" of the workpiece. In skin-effect heating, the high frequency is tightly controlled to produce a quality part.

Rf Heating is Induction Heating

Rf generators are advanced, solid state, induction power suppliers. Like all induction equipment, rf generators are versatile: they can heat large or small parts; they can separate the power supply from the heating station; they can be customized to meet any specified need in an operation. Moreover, they are economical both in terms of capital outlay and daily operation. Rf heating is quiet, safe, and energy efficient.

Applications

Because of its rapid, localized heating, rf heating can be used in hardening, annealing, soldering, brazing, and other heat treating processes. Rf preheating is used on plastics-molding materials to reduce the processing time. Because of the accuracy and precision of induction equipment, rf heating is ideal for small and large businesses and industrial operations.
