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 |
20110315308 | METHOD FOR PRODUCING HOLLOW BODIES FROM THERMOPLASTIC MATERIAL AND DEVICE FOR CARRYING OUT THE METHOD - 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. | 12-29-2011 |
