Zusammenfassung:	Injection moulding apparatus comprising a mould cavity (34) having an inlet (26) for injection of mouldable material, and a region (14, 16) in which at least two flow fronts of mouldable material meet in use due to the disposition of an insertion 30 to form a hole 12 in the article 10 to be made by the apparatus, wherein means (40) is provided for effecting by physical contact therewith localised movement of the mouldable material in said region in use. The means 40 is a rotatable member which is flush with surface 28 of a plate 22 defining mould cavity 34 with plate 24 so that member 40 does not protrude into the cavity 34.
