Process for moulding a thermoplastic material by injection onto a rotating core, in which the relative rotation of the various parts of the mould takes place during at least a part of the dwell stage and ends before the end of this stage. This process, which yields good results with polyolefins, makes it possible to manufacture articles such as receptacles and cylinders, exhibiting good mechanical properties.
