Abstract

An electrically heated tip assembly, particularly useful with a cyclically operated thermal press usable for forcible placement of inserts of hard material within bases of softer materials, includes a generally longitudinal tubular core member formed of a thermally conductive material. The core encloses an electric resistance heating element and has a tip element secured to one end thereof in heat exchange relationship with the heating element. The tip element includes a protruding finger member engageable with an insert and a paraboloidal section between the core member and protruding finger member to facilitate the concentration of heat downwardly into the finger member during the insertion portion of the operating cycle of the press. A heat dissipation member, including a plurality of spaced, outwardly extending, annular disks forming a generally upwardly extending envelope of overall paraboloidal configuration, is adjustably positioned about the core to facilitate the dissipation of heat from the tip element and core member inbetween cycles of operation of the press.
