The method and the device serve for the blow molding of containers. A preform of a thermoplastic material is first subjected to thermal conditioning in the region of a heating section along a transporting path. Subsequently, the preform is transformed into the container inside a blow mold by the effect of blowing pressure. The thermal conditioning of the preforms is carried out by a number of radiant heaters positioned one above the other. The radiant heaters are activated during production in accordance with a first heating profile and activated during standby mode in accordance with a second heating profile (), which is different from the first heating profile.

Method and device for blow molding containers

A method and device serve the tempering preforms of a thermoplastic material. The preforms are modeled subsequent to tempering into a container inside a blow-molding mold by the action of a medium under pressure. During tempering, the preforms are heated by being acted upon by a heat radiation as well as cooled by being blown upon with cooling air, at least in the surface region. For compensation of a change in the surface temperature of the preforms due to operating ambient parameters, a change in the intensity in the subjecting of the preforms to cooling air is conducted. This takes place such that with simultaneous heating and cooling a basically constant surface temperature of the preform is attained. In addition, the intensity of heat radiation can be regulated for adaptation to at least one operating parameter.
