PCT No. PCT/DE93/00987 Sec. 371 Date Jun. 12, 1995 Sec. 102(e) Date Jun. 12, 1995 PCT Filed Oct. 16, 1993 PCT Pub. No. WO94/08770 PCT Pub. Date Apr. 28, 1994In a temperature-controllable tool (11) or mould for producing plastic mouldings with at least one cavity (12) to accept the mould of the plastic moulding to be produced, at least one inlet or outlet aperture (13, 14) which are interconnected via channels (15) and form a temperature-control agent channel system for cooling or heating the mould cavity (12), the shot time (cycle time) is shortened, maintenance is made easier and higher quality injection-moulded components are obtained in that the run of the channels (15) is matched to the outer shape of the mould cavity (12) and the geometry of the channels (15) is matched to the temperature profile in the plastic moulding. A process for making such a tool or mould comprises the following steps: separating the tool or the mould in the planes of the channels to be produced; producing the channels in accordance with the desired cycle in at least one separating surface of the opened tool or mould by milling or the like; and joining the separated parts of the tool or mould together.
