A system for forming a container includes an injection station configured to inject a liquid material into a mold to form a preform. The system also includes a forming station including an apparatus for forming a container. The apparatus includes a blow mold configured to receive the preform and inject air into the preform to form the container. The blow mold includes an inner mold surface. The apparatus also includes at least one stretching rod configured to contact the preform in the blow mold and stretch the preform. The apparatus further includes electric heating elements coupled to the blow mold and positioned adjacent the inner mold surface to heat the inner mold surface. The system further includes a removal station configured to release the container from the system.

The invention relates to a preform for producing a plastic container in a 2-stage stretch blow molding method, said preform having a preform body that extends along a central axis and that comprises: a first end a second end that lies opposite the first end, wherein the first end is closed and a neck part with a pouring opening adjoins the second end; and an inner wall that delimits an interior of the preform. Along a length of at least 30 mm of the interior, every point of the inner wall is at a distance of less than 3.5 mm from the central axis. Also disclosed are a suitable method and a device for producing such a preform.

A liquid blow molding apparatus includes a rod guide interposed between the seal body and the stretching rod to suppress misalignment in the radial direction of the stretching rod with respect to the seal body and to seal a gap between the seal body and the stretching rod in a fluid-tight manner, and the seal body has a detachable portion detachably attached to the main body of the seal body to hold the rod guide between the detachable portion and the main body.

A stretch blow molding process for producing a plastic container from a preform, having an elongated, tubular preform body, extending along a center axis. The first end of the preform body is closed by a preform bottom and the second end is adjoined by a neck part with a pouring opening. A wall, bounds an interior space of the preform. The preform body is heated and introduced into a cavity of a blow mold. A stretching mandrel enters the preform until the stretching mandrel tip reaches the preform bottom. The preform body and the preform bottom are stretched by the stretching mandrel. The preform body and the preform bottom are deformed by introducing a fluid into the preform under pressure. The stretching mandrel makes contact with the inner side of the wall in the region of the preform body.
