Plural blow molding with servo controls

A method for forming a container from a preform comprising:

• blow molding a first form from the preform inside a plurality of first portions of a first blow mold;
• opening and closing the first portions of the first blow mold with a first mold servo motor;
• blow molding a second form from the first form inside a plurality of second portions of a second blow mold;
• opening and closing the second portions of the second blow mold with a second mold servo motor;
• individually controlling the first and second mold servo motors with a controller to individually control the opening and closing of the first and second blow molds;
• and
• individually controlling the opening and closing speed, and opening and closing timing, of the first and second blow molds with the controller, by sending different control signals to each of the first mold servo motor and the second mold servo motor.

A system for forming a plurality of containers, the plurality of containers being formed from a respective preform, the system comprising:

• a plurality of first molds, each of the plurality of first molds having a plurality of first portions that cooperate to define an first internal surface against which the respective preform is blown for forming a first form;
• a plurality of second molds, each of the plurality of second molds having a plurality of second portions that cooperate to define a second internal surface against which a respective one of the first forms is blown for forming a second form;
• a plurality of first mold servo motors, each of the plurality of first mold servo motors operable to actuate the plurality of first portions of one of the plurality of first molds relative to each other;
• a plurality of second mold servo motors, each of the plurality of second mold servo motors operable to actuate the plurality of second portions of one of the plurality of second molds relative to each other;
• a controller that controls the plurality of first mold servo motors and that controls the plurality of second mold servo motors for controlled actuation of the first portions and the second portions, by sending different control signals to each of the first mold servo motor and the second mold servo motor.
