Abstract
A system for forming a container from a preform includes a first mold having a plurality of first portions that cooperate to define a first internal surface against which the preform is blown for forming a first form. The system also includes a second mold having a plurality of second portions that cooperate to define a second internal surface against which the first form is blown for forming a second form. Also, the system includes a mold servo motor that actuates the plurality of first portions relative to each other and/or actuates the plurality of second portions relative to each other. Furthermore, the system includes a controller that controls the mold servo motor for controlled actuation of the plurality of first portions and/or the plurality of second portions.
