The nozzle is used for the processing of plastics. Its usagereduces the injection losses. The nozzle consists of a steelcylinder (10) with a flange (11). In the lower part of cylinder(10) concentric cavity (12) is machined, and at its other endthere are two plane surfaces (13) inclined to its longitudinalaxis towards each other at an angle of from 70 to 140°. In eachsurface (13) an orientated groove (14) is bored. The grooves forman angle of 70-140°C in between, the peak of which is outside thenozzle.5 claims, 3 figures
