    Abstract: A method of hydroforming a container from a preform. During the method, an injection nozzle is moved from a retracted position, where the nozzle is spaced away from the neck of the preform, to an intermediate position, where contact is established between a first contact surface of the nozzle and the finish of the preform. The nozzle is then moved from the intermediate position to an injection position, where a second contact surface of the nozzle abuts an abutment surface and the neck is axially compressed. With the nozzle in the injection position, a liquid is injected from the nozzle into the preform causing the preform to expand and form the container.

    Abstract: An injection device for injecting a pressurized liquid into the preform. The injection device includes a piston device having a piston body with a piston head arranged to reciprocate therein. The piston head cooperates with a sealing portion of the piston body to fluidicly isolate an inner chamber of the piston device. The piston body being in fluidic communication with a liquid source for admitting liquid into the inner chamber. The piston body including at least two outlet ducts for delivering pressurized liquid to the injection head. Each outlet duct opening defining an outlet port in a wall of the inner chamber. Each outlet port being centered on an outlet port center, wherein all the outlet port centers extend in the same radial planes of the inner chamber, are at the same distance from the piston axis and are arranged angularly in a regular manner around the piston axis.
