  • Patent number: 10183436
    Abstract: 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.

  • Patent number: 8968634
    Abstract: 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.
