Abstract

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.
