Stretch blow moulding method for manufacturing a plastic container from a preform which has an elongated tube-shaped preform body, extending along a central axis of the preform, with a first end and a second end substantially opposed to the first end, wherein the first end is closed by a preform body and a neck part with a spout opening follows the second end, and with a wall that limits an inner space of the preform with an inner side and an outer side, wherein - the preform body is heated up to at least 70°C, - the preform is placed into a cavity of a blow mould, - a stretching mandrel with a stretching mandrel body and a stretching mandrel tip is driven into the preform until the stretching mandrel tip reaches the preform bottom, - the preform body and the preform bottom are stretched into the cavity by the stretching mandrel, - the preform body and the preform bottom are deformed in a manner so as to correspond to the cavity by filling in a fluid into the preform under pressure, wherein the stretching mandrel, while being driven into the preform until it reaches the preform bottom, touches the inner side of the wall in the area of the preform body on at least one predetermined partial area and wherein the extension of the stretching mandrel perpendicularly to the central axis of the stretching mandrel inside an area that follows the tip of the stretching mandrel is at least as large as the extension of the inner space of the preform perpendicularly to the central axis of the preform inside an area that follows the bottom of the preform, area that has a length of at least 5, 10 or 20 millimeters parallel to the central axis, characterized in that the preform, after the heating of the preform and/or when the stretching mandrel is driven into the preform, has a temperature on the inner side of the wall, in particular in the area of the preform body, that is at least 5°C higher than on the outer side of the wall, in particular in the area of the preform body. - the preform body is heated up to at least 70°C, - the preform is placed into a cavity of a blow mould, - a stretching mandrel with a stretching mandrel body and a stretching mandrel tip is driven into the preform until the stretching mandrel tip reaches the preform bottom, - the preform body and the preform bottom are stretched into the cavity by the stretching mandrel, - the preform body and the preform bottom are deformed in a manner so as to correspond to the cavity by filling in a fluid into the preform under pressure, wherein the extension of the stretching mandrel perpendicularly to the central axis of the stretching mandrel inside an area that follows the tip of the stretching mandrel is at least as large as the extension of the inner space of the preform perpendicularly to the central axis of the preform inside an area that follows the bottom of the preform, area that has a length of at least 5, 10 or 20 millimeters parallel to the central axis, characterized in that the preform, after the heating of the preform and/or when the stretching mandrel is driven into the preform, has a temperature on the inner side of the wall, in particular in the area of the preform body, that is at least 5°C higher than on the outer side of the wall, in particular in the area of the preform body.
