Method and device for regulating the temperature of parisons |
摘要 |
The method and the 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.
