ABSTRACT:
The mould used in manufacturing moulded articles is cooled by cooling fluid flowing along a cooling passage in the mould. In order to concentrate the cooling effect in a desired central region of the cooling passage, an exit portion of the passage is enlarged relative to the central region. If desired, the entrance portion may also be enlarged to further concentrate the cooling effect.
