    • A method and apparatus for blow molding containers is disclosed, the method including the steps of; a) heating a preform to a desired temperature in an oven having a plurality of heating units in a stack; b) blow molding a container from the heated preform; c) measuring a wall thickness at a desired location along a longitudinal axis of the container; d) generating a signal representing the wall thickness; e) comparing the signal representing the wall thickness to a standard range of wall thickness measurements; and f) adjusting the energy output of the plurality of heating units of the oven to affect the production of subsequent containers if the signal is not within the standard range, wherein the energy output of at least one heating unit is increased and the energy output of at least another heating unit is decreased by an amount equal to the increase.
    • 公开了一种吹塑容器的方法和装置,该方法包括以下步骤: a)在具有堆叠中的多个加热单元的烘箱中将预成型件加热到所需温度; b)从加热的预制件吹塑容器; c)沿着容器的纵向轴线在期望的位置测量壁厚; d)产生表示壁厚的信号; e)将表示壁厚的信号与壁厚测量的标准范围进行比较; 以及f)如果所述信号不在所述标准范围内,则调节所述烘箱的所述多个加热单元的能量输出以影响随后的容器的产生,其中至少一个加热单元的能量输出增加,并且 至少另一个加热单元减少等于增加的量。
