Abstract:
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.
