Liquid or hydraulic blow molding

A system for simultaneously forming and filling a container comprising:

• a plurality of mold cavities each defining an internal surface and adapted to accept a preform;
• a pressure source having a single servo motor system operably coupled with the plurality of mold cavities to supply a liquid to at least one of the plurality of mold cavities, the single servo motor system operable in a first upward direction wherein liquid is drawn from an inlet and a second downward direction wherein liquid is urged toward the preform associated with the at least one of the plurality of mold cavities;
• and
• a blow nozzle adapted to receive the liquid from the pressure source and transfer the liquid at a pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the liquid remains within the container as an end product.
