Abstract

Improvements in the object of the main patent no. 455,627 for "improvements in the manufacture of injected parts of plastic materials of composite structure", essentially characterized in that, in the injection of pieces consisting of three zones of different materials forming a single body, each of the molding spaces corresponding to said zones remains in communication with the respective injection nozzle, including, in the regions corresponding to the contact zones between each pair of different materials, a set of movable blades initially arranged to limit, in a first phase, the passage of plastic materials forming the extreme areas of the piece, which will be injected first and simultaneously.
