An article enclosing at least one built-in fitment component in the form of a hollow body of thermoplastic material. The hollow body is preferably in the form of a fuel tank. The built-in fitment component is pressed 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.

Container of thermoplastic material

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.

Method for producing a container of thermoplastic material

A blow molding tool () for producing a plastic article, in particular a fuel tank, comprising at least one clamping frame () with mold clamping devices () and at least two blow mold halves, which are formed such that they can be moved together and apart by means of an opening and closing movement of the clamping frame () and which respectively have at least one cavity () for the forming of the plastic article, the blow molding tool () being distinguished by the fact that the mold clamping devices () respectively have at least one tool holder (), in which a mold insert () is in each case exchangeably inserted, and in that the tool holders () respectively form a peripheral sealing edge ().

Blow molding tool and method for producing extrusion blow molded plastic articles

The invention concerns a mold tool for the production of extrusion blow molded products, comprising at least three mold portions () which define a mold cavity () and of which two are in the form of outer molds () and one is in the form of a central mold (). The outer molds () and the central mold () are displaceable from and towards each other in the sense of an opening and closing movement of the tool. The central mold () is provided with component holders () which can be moved out of and into the tool plane defined by the central mold and are arranged in turn on a carrier () which is also displaceable with respect to the central mold ().

Mold tool for the production of extrusion blow molded products

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.
