METHOD FOR PRODUCING A PLASTIC HOLLOW BODY AND A PLASTIC CONTAINER

摘要

The invention relates to a method for producing an article that encloses built-in parts and has the form of a hollow body made of thermoplastic material. The hollow body is advantageously embodied as a fuel container. The method consists in the extrusion of one or several web-type or tubular premoulds of plastified material, said premoulds being pressed against the open parts of a moulding tool forming a cavity. At least one built-in part to be enclosed by the finished article is placed between the parts of the moulding tool, the tool being closed around the premoulds and the built-in part. The premoulds take the exterior form of the article within the cavity enclosed by the tool. The built-in partis are pressed against the inner wall of the yet plastic material during or immediately after the moulding process so that the plastic of the hollow body penetrates and flows after at least one recess or opening of the built-in part.
