Publication number: 20140178522Abstract: The invention relates to a method for producing hollow bodies from thermoplastic material, comprising the molding of at least two sheet-like, web-shaped preforms of plasticated thermoplastic material in a multi-part tool forming a cavity to form two complementary shells, and also the joining together of the shells to form a substantially closed hollow body, wherein the preforms are brought between open parts of the tool which each have part-cavities, the parts of the tool are then closed against a tool separator arranged between the preforms, and the preforms are inserted into the part-cavities with the use of differential pressure and molded. In a subsequent separate method step, the tools are reopened and internal components of the hollow body to be produced are fastened to the shells. Finally, the shells are joined together by reclosing the tools to form a closed hollow body.Type: ApplicationFiled: December 6, 2013Publication date: June 26, 2014Applicant: Kautex Textron GmbH & Co.

Publication number: 20130119077Abstract: The invention relates to a method for the riveted fastening of an accessory to a plastics fuel tank (11, 12), the riveted fastening taking place at the time of the production of the tank by extrusion blow-moulding of a split tubular preform or two web-like extruded preforms made of thermoplastic material by using a multi-part die after or during the moulding of two complementary shells. The accessory (4) has been provided or is provided with at least one opening. The method according to the invention is characterized in that the riveted fastening takes place by means of at least one prefabricated rivet pin (9) made of thermoplastic material. The rivet pin has been obtained in a separate production process, for example by injection-moulding.Type: ApplicationFiled: June 30, 2011Publication date: May 16, 2013Applicant: KAUTEX TEXTRON GMBH & CO.

Patent number: 8147232Abstract: The invention concerns a mold tool for the production of extrusion blow molded products, comprising at least three mold portions (2a, 2b, 3) which define a mold cavity (4) and of which two are in the form of outer molds (2a, 2b) and one is in the form of a central mold (3). The outer molds (2a, 2b) and the central mold (3) are displaceable from and towards each other in the sense of an opening and closing movement of the tool. The central mold (3) is provided with component holders (11) which can be moved out of and into the tool plane defined by the central mold and are arranged in turn on a carrier (10) which is also displaceable with respect to the central mold (3).Type: GrantFiled: June 8, 2007Date of Patent: April 3, 2012Assignee: Kautex Textron GmbH & Co.

Patent number: 8003041Abstract: The invention concerns a process for the production of hollow bodies of thermoplastic material. In the process according to the invention preforms in web or band form of plasticized material are shaped in a multi-part tool forming a mold cavity comprising two outer molds and at least one central mold which perform an opening and closing movement relative to each other. The central mold is provided with at least one component holder which can be moved of and into the tool plane defined by the central mold. In a first step the component holder is fitted with at least one insert portion, then the insert portion is placed by means of the component holder against the inside wall of an outer mold.Type: GrantFiled: June 8, 2007Date of Patent: August 23, 2011Assignee: Kautex Textron GmbH & Co.

Publication number: 20080006625Abstract: The invention concerns a process for the production of an article enclosing built-in fitment components in the form of a hollow body of thermoplastic material. The hollow body is preferably in the form of a fuel tank. The process includes the extrusion of one or more preforms in web or tube form of plasticized material between the opened portions of a mold tool forming a cavity, wherein at least one built-in fitment component to be enclosed by the finished article is placed between the portions of the mold tool and the tool is closed around the preforms and the built-in fitment component, wherein the preforms within the cavity enclosed by the tool acquire the external configuration of the article. The built-in fitment component is pressed during or directly after the shaping operation against the inside wall of the article while still plastic so that the plastic material of the hollow body penetrates through at least one recess or opening of the built-in fitment component and flows therebehind.Type: ApplicationFiled: July 3, 2007Publication date: January 10, 2008Applicant: KAUTEX TEXTRON GMBH & CO.
