Abstract
A method of and an apparatus for producing a hollow body of thermoplastic includes the steps of injection molding a first hollow body part with an outward-protruding first joining edge, injection molding at least a second hollow body part with an outward-protruding second joining edge, putting the hollow body parts together at the first and second joining edges, and connecting the first and the at least one second hollow body part by a molded, at least partially U-shaped sealing portion comprising a thermoplastic.

A method for producing a hollow body of thermoplastic, the method comprising the following steps:
- injection molding a first hollow body part with an outward-protruding first joining edge;
- injection molding at least a second hollow body part with an outward-protruding second joining edge;
- putting the hollow body parts together at the first and second joining edges;
- and
- connecting the first and the at least one second hollow body part by molding an at least partially U-shaped sealing portion encompassing the two joining edges, the sealing portion comprising a thermoplastic.
An apparatus for producing a hollow body of thermoplastic with at least one component inserted into it, the apparatus comprising
- a first injection molding device integrated with the apparatus for injection molding at least two hollow body parts;
- a mounting device integrated with the apparatus for mounting the at least one component in at least one of the hollow body parts and for putting the hollow body parts together at joining edges;
- and
- a second injection molding device, integrated with the apparatus, for connecting the hollow body parts by injection molding of a thermoplastic at the joining edges.
A hollow body of thermoplastic, comprising
- at least two injection molded, put-together hollow body parts, on each of which an outward-protruding joining edge, is embodied;
- and
- an injection molded sealing portion, which is designed as at least partly U-shaped in cross section and embracing the joining edges.
