  • Patent number: 9352506
    Abstract: 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.

  • Publication number: 20110129560
    Abstract: The invention concerns a nozzle for the production of hollow bodies of thermoplastic material by extrusion blow molding. According to the invention, continuous extrusion of at least two preforms in web form of plasticized material is effected by means of a plurality of extrusion devices. The preforms are jointly shaped to form a hollow body in the still plastic condition, that is to say, in the first heat, within a multi-part tool forming a mold cavity. In that case, a wall thickness profile is imparted to at least one preform during the extrusion operation independently of the respective other preform by continuous nozzle gap adjustment during the extrusion operation.
