The invention relates to a method for producing a plastic article and a blow molding tool for performing the method. The method comprises extruding an approximately tube-shaped preform, dividing the melt flow within the extrusion head or separating the extrudate exiting or already exited from the extrusion head, such that a preform having an approximately C-shaped cross section is obtained, forming the preform into a hollow part within a multipart blow molding tool using differential pressure, wherein an expansion and partial preforming of the preform first takes place with the blow molding tool partially closed, then in a further step at least one insert is inserted into the interior of the partially preformed article between the not completely closed blow molding tool and through the open side of the preform, and in a further step the blow molding tool is completely closed, wherein the article is completely formed, forming at least one at least partially circumferential pinch-off seam.

Method for producing a plastic article and blow molding tool

A method for producing a plastic article includes extruding an approximately tubular blank from an extrudate and shaping the blank into a hollow body inside a blow-mold using differential pressure, wherein at least one insertable part is introduced into the interior of the partially molded plastic article before the latter is fully shaped into a finished plastic article, and the tubular blank is arranged between at least two halves of a blow-mold by means of an intermediate frame.

Method for producing a plastic article, and part of a blow-mould

The invention relates to a method for producing an article from thermoplastic material in which a tube-shaped preform is introduced into a multi-part blow mold and is expanded and formed by applying differential pressure, wherein, before the forming of the preform, at least one insert is introduced into the preform by means of a first holding means and wherein, before the forming of the preform, the insert is taken over by at least one second holding means puncturing the wall of the preform, the second holding means being formed as a blowing pin and an expansion and re-forming of the preform taking place by applying pressure medium with the second holding means.

The invention relates to a pressure vessel for the storage of liquid or gaseous media. The pressure vessel () comprises a plastic inner vessel () with at least one neck piece () which is not connected in one piece with the latter and which is arranged on the vessel neck in the region of the vessel orifice (), and with a supporting jacket () at least partially surrounding the plastic inner vessel () and the neck piece (). The neck piece () is provided with means for receiving a connection fitting (). The pressure vessel according to the invention is distinguished by an insert () which forms at least part of the vessel neck and which forms a sealing seat for the fitting () to be inserted into the neck piece ().
