    摘要： 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.

    摘要： 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.
