Abstract

The invention relates to a device for producing hollow bodies from thermoplastic material in which web- or strip-type preforms of plasticized plastics material are shaped in a multi-part tool which forms a mold nest, with two outer molds and a central mold which perform opening and closing movements with respect to one another. The central mold is provided with at least one device for receiving and manipulating components to be fastened in the interior of the hollow body by means of a material and/or form-fitting joint. Prior to the fastening of the components to the inner wall of the hollow body to be produced, the components are heated by means of a radiant heating device. The radiant heating device is advantageously integrated in the central mold of the tool.
