Process for temperature-control of preforms and temperature-control device |
摘要 |
The method serves for tempering preforms made of a thermoplastic material. The preforms are provided for blow deformation into containers. The preform is provided with a temperature profile along the periphery. The temperature profile is produced in that striplike regions extending in the direction of the longitudinal axis of the preform are heated differentially. Stepwise tempering is carried out for successively timed thermal conditioning of various regions of the preform.
