Реферат: The invention relates to a process for the cryogenic production of blow moulded plastic parts, whereby air is used as the blowing medium and is fed into a preform (8) in a blow mould, and the preform (8), which is deformable when hot, is blown-up with the air through a blow mandrel (15) before being cooled with dried, cooler air. According to the invention, the air used as a blowing medium is dried before being introduced into the preform, and the dried air is fed into the blown-up preform in a super-cooled state, with a temperature of between approximately -50 °C and -170 °C, in order to cool the preform. While the blow mould is open, it and/or the blow mandrel are flushed with dry and preferably warm air.
