Zusammenfassung:	PCT No. PCT/EP87/00532 Sec. 371 Date Mar. 10, 1989 Sec. 102(e) Date Mar. 10, 1989 PCT Filed Sep. 17, 1987 PCT Pub. No. WO88/01928 PCT Pub. Date Mar. 24, 1988.To provide a thermodynamic pinpoint gate nozzle which will permit a so-called cosmetic gate without stringing, and during which the plastic material to be processed is not subjected to high viscous or shear stress by the heating elements placed inside the nozzle channel, it is provided that the pinpoint gate nozzle on the side facing the mold cavity exhibits a low-mass inside nozzle (7) and that inside nozzle (7) can be heated by an ohmic resistance wire either inductively or by inside nozzle (7) formed as a Peltier element.
