Abstract: Provided is a stretching rod for a molding unit for manufacturing a container from a preform and a method for manufacturing a container by stretch blow-molding. The stretching rod extends longitudinally, parallel to a main axis Y, and comprises a body of cylindrical or tubular form, a distal end in the extension of said body, at least one internal channel to allow the circulation of a cooling gas to said distal end, a flat situated at the distal end of the stretching rod, an end-fitting protruding from said flat and a plurality of orifices, said orifices being fluidically connected with said internal channel and being distributed around said end-fitting on said flat. The rod can include an annular skirt in the extension of said body, at said distal end, said skirt having a height less than the height of said end-fitting.

Abstract: A Molding unit for the forming of a container includes: a mold provided with a side wall defining a cavity bearing the impression of a portion of the container; an insert having a frontal surface bearing the impression of a local portion of the container, movable between a retracted position and a deployed position, with this insert being penetrated by ducts; a pierced piston to which the insert is attached and which ensures the mobility of the latter between its retracted position and its deployed position; and at least one pierced screw by which the insert is attached to the piston.
