System for simultaneously forming and filling a container comprising: a mold having a mold cavity defining an internal surface and adapted to accept a preform; a pressure source urging a first liquid toward the preform; a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure or volume into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the first liquid remains within the container as an end product; the system being characterized in further comprising: a pressure compensation system exerting a clamping force on said mold in response to said pressure source, wherein said pressure compensation system comprises: a compensation pressure applicator operably engaging said mold for exerting said clamping force; and an isolator system, operably coupled to said pressure source for transferring a pressure from the first liquid to a line coupled to said compensation pressure applicator, wherein said isolator system comprises an isolator cylinder transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid, or wherein said isolator system comprises a diaphragm transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid. a mold having a mold cavity defining an internal surface and adapted to accept a preform; a pressure source urging a first liquid toward the preform; a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure or volume into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the first liquid remains within the container as an end product; the system being characterized in further comprising: a pressure compensation system exerting a clamping force on said mold in response to said pressure source, wherein said pressure compensation system comprises: a compensation pressure applicator operably engaging said mold for exerting said clamping force; and an isolator system, operably coupled to said pressure source for transferring a pressure from the first liquid to a line coupled to said compensation pressure applicator, wherein said isolator system comprises an isolator cylinder transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid, or wherein said isolator system comprises a diaphragm transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid. a compensation pressure applicator operably engaging said mold for exerting said clamping force; and an isolator system, operably coupled to said pressure source for transferring a pressure from the first liquid to a line coupled to said compensation pressure applicator, wherein said isolator system comprises an isolator cylinder transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid, or wherein said isolator system comprises a diaphragm transferring said pressure from the first liquid to a second liquid disposed in said line, said first liquid being fluidly isolated from said second liquid.
