Abstract: Process for manufacturing a plastic container (13) by blow moulding, in which a preheated preform (5) is placed in a mould (1, 2), while leaving part of the preform (5) intended to form the neck (6) of the container (13), outside the mould (1, 2), and a pressurized gas is blown into the preform (5), the deformation of said preform being assisted by stretch means, so as to make it conform to the internal walls of the mould (1, 2), characterized in that said stretch means apply a stretch force of at least 4 N to said preform (5) after a time of at most 1/30 s following the start of stretching, so as to make the material of the preform (5) undergo a displacement of at least 1/100 mm during this period. Device for implementing this method.
