| 摘要 |
The invention relates to a method for producing a moulded part (1) with a rotationally symmetrical or at least partially annular cross-section, such as a nut, a collar, a pipe connector, pipe coupling or similar. According to said method, a plasticized polymeric mass (PM) containing fibres (F) is injected through an injection opening (O1) into a cavity (K) of a moulding tool and once the polymeric mass (PM) has solidified, the moulded part (1) is removed from the tool. The aim of the invention is to produce a moulded part (1) with improved strength and preferably optimal shrinkage during the solidification of the polymeric mass (PM) using simple technology. To achieve this, injection into the cavity (K) takes place through at least two injection openings (O1, O2, O3) in such a way that the fibres (F) are aligned predominantly in the main stress directions of axial tension (Z) and torsion (T) in the moulded part (1). |
