| 20080290564 | PROCESS FOR THE PRODUCTION OF A CONTAINER OF THERMOPLASTIC MATERIAL BY EXTRUSION BLOW MOLDING AND A CONNECTION ELEMENT FOR USE IN SUCH A PROCESS - The invention concerns a process for the production of a container of thermoplastic material by extrusion blow molding, in which during shaping of the container within a multi-part tool the container is provided with at least one connection element ( | 11-27-2008 |
| 20090045542 | PROCESS FOR THE PRODUCTION OF HOLLOW BODIES OF THERMOPLASTIC MATERIAL - 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. In a further step introduction and shaping of the preforms within the tool is effected in a two-stage procedure, wherein firstly the preforms are respectively applied against a contour forming a part of the mold cavity by means of increased pressure and/or reduced pressure and shaped and then the intermediate products forming respective parts of the hollow body are joined together to form a finished product. | 02-19-2009 |
| 20090047375 | MOLD TOOL FOR THE PRODUCTION OF EXTRUSION BLOW MOLDED PRODUCTS - The invention concerns a mold tool for the production of extrusion blow molded products, comprising at least three mold portions ( | 02-19-2009 |
| 20090102102 | PROCESS FOR THE PRODUCTION OF HOLLOW BODIES OF THERMOPLASTIC MATERIAL BY EXTRUSION BLOW MOLDING - The invention concerns a process for the production of hollow bodies of thermoplastic material by extrusion blow molding. In the process 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. | 04-23-2009 |
| 20090308881 | METHOD FOR PRODUCING A FUEL CONTAINER FOR MOTOR VEHICLES AND FUEL CONTAINER FOR MOTOR VEHICLES - The invention relates to a method for producing a fuel container and to a fuel container for motor vehicles. The method comprises the extrusion of web-type preforms, the shaping of the preforms in the first heat of the extrudate in a multi-part moulding tool to form shell-shaped intermediate products in a first step, and to form a one-piece, closed container in the same moulding tool in a second step, at least one tank-filling and/or operational venting device being fastened to the inner wall of at least one intermediate product between the first and second steps in such a manner that at least one preassembled part of the tank-filling and/or operational venting device with at least one connection fitting, at least one vent line and at least one functional component is connected to the inner wall by a material and/or form-fitting joint in one work cycle, the wall of the intermediate product being penetrated by the connection fitting during assembly, with the use of at least one conduit section of variable length as a part of the vent line. | 12-17-2009 |
| 20090309270 | METHOD FOR PRODUCING HOLLOW BODIES FROM THERMOPLASTIC MATERIAL, AND DEVICE FOR PRODUCING HOLLOW BODIES FROM THERMOPLASTIC MATERIAL - The invention relates to a method for producing hollow bodies from thermoplastic material in which web- or strip-type preforms of plasticised plastics material are shaped in a multi-part tool which forms a mould nest, with two outer moulds and a central mould which perform opening and closing movements with respect to one another. The central mould is provided with at least one device for receiving and manipulating components to be fastened in the interior of the hollow body by means of a material and/or form-fitting joint. Prior to the fastening of the components to the inner wall of the hollow body to be produced, the components are heated by means of a radiant heating device. The radiant heating device is advantageously integrated in the central mould of the tool. | 12-17-2009 |
| 20100282759 | METHOD FOR THE PRODUCTION OF HOLLOW BODIES FROM THERMOPLASTIC PLASTIC - The invention relates to a method for the production of hollow bodies from thermoplastic plastic. The method comprises the extrusion of at least two sheet-like preforms consisting of thermoplastic plastic, the introduction of the preforms into a preferably multipart molding die with a molding cavity which at least partially defines the contour of the hollow body to be manufactured, and the shaping of the preforms inside the die, using a vacuum and/or gas pressure in the first heat of the material. The method is distinguished in that at least two preforms to be shaped into a hollow body and to be connected are extruded successively, that is to say sequentially, in time and are shaped simultaneously. | 11-11-2010 |
| 20100304943 | FUEL TANK OF THERMOPLASTIC MATERIAL WITH FUNCTIONAL INSTALLATION FITMENTS FOR AIR INTAKE AND VENTING, FOR FUEL TAKE-OFF AND THE LIKE - The invention concerns a fuel tank of thermoplastic material, comprising functional installation fitments for air intake and venting, for fuel take-off or the like, which is distinguished in that at least one functional installation fitment is connected to the inside wall of the container in material-bonded relationship in such a way that the functional installation fitment defines with the container wall a volume separated from the filling volume of the container in such a way that the inside wall of the container serves directly as a boundary wall of said volume. | 12-02-2010 |
| 20110129560 | Nozzle For The Production Of Hollow Bodies Of Thermoplastic Material By Extrusion Blow Molding - 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. | 06-02-2011 |
