A method of shaping plastics material pre-forms into plastics material containers, in which the plastics material pre-forms are expanded by compressed air to form the plastics material containers, in which before the expansion the plastics material pre-forms are pre-heated on a heating path of a heating device, and in which the plastics material pre-forms are conveyed by a heating path conveyor along the heating path from a heating path supply device to a heating path removal device, wherein the plastics material pre-forms are sterilized at least in part on the heating path, wherein the plastics material pre-forms held on holding elements of the heating path conveyor are sterilized directly on a sterilization device.
