The invention relates to a method for producing a moulded part (1) with an annular cross section, such as a screw, a nut, a socket part, a pipe plug, a pipe connector or the like, wherein the moulded part (1) has a hollow-cylindrical main body (2), in the inner channel (3) of which, intended for receiving a plug part (4) in a sealing manner, there are in series with one another in the axial direction (X-X) portions (A1, A2, A3, A4, A5, A6, A7, A8, A9, AZ) with different functions, to be specific for bearing a circumferential seal (5, 6), for directly or indirectly securing and/or arresting the plug part (4) and/or for supporting and/or guiding the plug part (4), and wherein the main body (2) bears at least one internal thread and/or external thread (10), wherein a plasticized polymeric compound containing fibres (F) is injected through at least one injection opening of a moulding tool into a cavity of the moulding tool and, after the polymeric compound has solidified, the moulded part (1) is removed from the tool. In order to increase in particular the torsional strength or the tensile strength in a way that ensures a reliable process and that the production of the moulded part can be carried out in a technologically simple manner, it is proposed that the injection into the cavity is performed radially from the inner channel (3) outwards in a portion (A1, A2, A3, A5, A7, A8) or in a region (14, 15) of a portion (A1, A2, A3, A4, A5, A6, A7, A8, A9, AZ) that does not serve for bearing a circumferential seal (5, 6) or securing and/or arresting the plug part (4). |
