In 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 apert ure (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 co mponents are obtained in that the run of the channels (15) is matched to the outer shape of the mould cavity (12) and the geo metry 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 ch annels 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.
