FIELD: technological processes.

SUBSTANCE: casting mould for making polymer objects consists of matrix, guide bushings and moulding channel with inner opening. The cast mould has detachable metallic cover, forced cooling channel and extra control moulding channel. The control moulding channel is in form of cylindrical opening. Moulding channels are installed in the central part of the detachable metallic cover of the casting mould at opposite sides from each other.
