An inductive heating technique for fast bonding of relatively thin metallic, mainly ferromagnetic, parts to nonmetallic components is described. The technique is intended primarily for the simultaneous handling of a number of elements thus reducing their assembly time. Heat is generated in the parts to be heated by a ferromagnetic structure supplied with currents at frequencies between 10 and 20 kHz. The method produces areas of uniformly distributed heat with sharply defined boundaries. The first successful application of this technique was the bonding of plastic retainer clips distributed over the length of a car body, to which a decroative molding was to be snapped. In this and other cases the parts are bonded to car bodies that are already painted; the resolution of problems associated with the upper safety limits of temperature tolerance of the point are discussed. The bonding of metal clips to curved glass and to plastic grids are also discussed.
