Zusammenfassung:	Described is an improved method of manufacturing an injection-moulding tool which contains cavities of complicated construction for the manufacture of shaped parts, for example rollers, the heating-cooling channels being made beforehand in the parts to be joined by milling, turning or drilling and these parts being joined together after prior cleaning by vacuum brazing with the use of brazing-wire material. After the vacuum brazing, the hardening of the assembled injection-moulding tool is carried out.
