FIELD: metallurgy.
SUBSTANCE: claimed process consists in that the polymer material melt is transformed in the injection mould into the cast to be withdrawn therefrom and cooled down. After the cast withdrawal from the mould and at its cooling it is subjected to reduction from the side of its mid surfaces.
EFFECT: higher efficiency of polymer cast fabrication, ruled out pulls and pipes.
