The invention relates to a hollow plastic side member (19), which is produced in a fluid-assisted internal pressure injection moulding process, in which, in an injection moulding step, a molten injection moulding compound of the plastic can be injected under pressure and heat into a mould cavity (33) of an injection mould (35), and in an internal pressure moulding step a fluid (G) is introduced into the tool cavity (33), by means of which step a molten plastic core is displaced and a hollow channel (23) is formed in the hollow plastic side member (19). According to the invention, a hollow profile insert (21) is embedded in the plastic material of the hollow plastic side member (19) to increase the component stability, which insert directly or indirectly annularly encloses the hollow channel (21) in the cross-section.
