Abstract: A nozzle terminal of an injector comprises a tip and a ring nut having respective distal ends one of which is configured so as to be coupled with a gate of a moulding cavity, it cooperates with the shutter terminal of the valve pin of the injector, and it has an overall thickness in cross-section which is equal to or less than that of the cross-section of the shutter terminal of the valve pin.

Abstract: A nozzle terminal for injectors of plastic material injection molding apparatus, includes an inner tubular body or tip and a ring nut. The tip includes a radially inner element made of a first material and a radially outer element made of a second material arranged at contact with the radially inner element at an intermediate portion thereof terminating at a distance from the distal end thereof. The ring nut fully covers the radially outer element, insulating it from the environment.

Abstract: A nozzle terminal for injectors of plastic material injection moulding apparatus, includes a tubular tip defining a flow passage for the injected plastic material and including a radially inner element made of a first abrasion resistant material, an intermediate element made of a second high thermal conductivity material, and a radially outer element made of a third corrosion resistant material. The radially inner, intermediate and radially outer elements are joined to each other in intimate mutual contact, and the radially outer element fully covers the intermediate element thus insulating it from the environment.

Abstract: A nozzle terminal for injectors of injection molding apparatus of plastic materials, includes an inner tubular body or tip defining a flow passage for injected plastic material, and an outer ring coaxial with the tip. The tip includes a radially inner element made of a first material and a radially outer element made of a second material, and arranged in contact with a substantial axial portion of the radially inner element up to the distal end thereof, and mechanically coupled thereto.
