    • A method for the temperature control and/or regulation of a heating device (10) for preforms (46) made from a thermoplastic material, the method being intended for controlling the temperature of the preforms (46) prior to a subsequent blow molding or stretch blow molding process. The temperature control process includes at least two distinct, consecutive heating stages (12, 14), where a near uniform base temperature of the entire preform (46) is achieved in the first heating stage (12). The base temperature approximately corresponds to a maximum heating temperature (T2) for maintaining the dimensional stability of the thread section at the preform's (46) open-topped neck section. An unevenly distributed softening temperature (T3) according to a predefineable thermal profile is achieved in the second heating stage (14), with the softening temperature (T3) being required for blow molding or stretch blow molding at least the preform's (46) body section located below the thread section and/or a collar area located therebelow. The invention furthermore includes a heating device (10) for performing the method.
    • 一种用于由热塑性材料制成的用于预成型件(46)的加热装置(10)的温度控制和/或调节方法,该方法用于在随后的吹塑或拉伸之前控制预成型件(46)的温度 吹塑工艺。 温度控制过程包括至少两个不同的,连续的加热阶段(12,14),其中在第一加热阶段(12)中实现整个预制件(46)的接近均匀的基础温度。 基础温度大致对应于用于维持预成型件(46)开口颈部处的螺纹部分的尺寸稳定性的最大加热温度(T2)。 在第二加热阶段(14)中实现了根据预定义热​​分布的不均匀分布的软化温度(T3),其中至少预成型坯体(46)的吹塑成型或拉伸吹塑成型需要软化温度(T3) 位于螺纹部分下方和/或位于其下方的凸缘区域。 本发明还包括用于执行该方法的加热装置(10)。

    • A method for the temperature control and/or regulation of a heating device (10) for preforms (46) made from a thermoplastic material, the method being intended for controlling the temperature of the preforms (46) prior to a subsequent blow molding or stretch blow molding process. The temperature control process includes at least two distinct, consecutive heating stages (12, 14). At least one temperature reading of the preforms after the first heating stage is taken, and deviations of the at least one temperature reading from a specified set point temperature is determined, a first temperature reading of the at least one temperature reading being taken after the first heating stage. Radiators in the second heating stage are regulated or adjusted as a function of the first temperature reading and temperature deviations of the preforms from the specified set point temperature are compensated for prior to exit of the preforms from the heating device. The invention further includes a heating device for performing the method.
