    Abstract: Machine for the production of receptacles of plastic. A stretching rod (32) is displaced by actuating means (69) comprising a servo-motor (72) whose operation is controlled by a controller installation (73) by means of an adjustment loop (75). The blowing air is introduced into the preform via a servo-valve (60) whose operation is also controlled by this installation (73) by means of an adjustment loop (76) which can be combined with the first adjustment loop (75). It is thus possible to control in a precise manner the process of transformation of a preform into a receptacle by means of curves of stretching and pressure increase. Calibration operations of the maximum path of the stretching rod as a function of the length of the mould cavities and calibration operations of the path of positioning of the stretching rod as a function of the preform can be carried out easily and in an automated fashion, thereby ensuring excellent safety of production and very high adaptability to all conditions of production.

    Abstract: A method for stretch blow molding a preform (21) in a mold cavity (205) is provided. The mold cavity (205) is coupled to a stretch blow molding system (200) including a cylinder (201), a piston (212) movable within the cylinder and a stretch rod (202) coupled to the piston. The method includes a step of actuating a first pre-blowing valve (234) from a first position to a second position to supply a first pre-blowing pressure to the preform (211) at a first pressure and a first flow rate. The method also includes a step of determining a stretch rod position and/or an elapsed time. While the first pre- blowing valve (234) remains actuated, the method actuates at least a second pre-blowing valve (234) from a first position to a second position based on the determined stretch rod position and/or the elapsed time to supply a second pre-blowing pressure to the preform at a second pressure and/or a second flow rate or exhaust pressure from the preform (211).
