ABSTRACT A Method of Producing an Injection Moulding Tool An injection moulding tool with optimum temperature distribution as the result of an improved tempering duct system is obtained if the tool inserts (10, 11) are each made up of two or more plates, tempering ducts (12, 12', 12") are worked in from the external faces (F1, F2, F3), on which the parts are subsequently joined by the diffusion welding method. An injection moulding tool for VHS reel hubs produced by this method produces moulds for injection moulding with substantially reduced wobble and a reduced cycle time. (Figure 3).
