Abstract

A composite part is produced by a process in which at least one of components a) and b) of said composite part is treated with an Openair plasma on a contact surface between said components a) and b) prior to production of the composite part, followed by molding-on of the other component; wherein said components are as follows: a) a part which entirely or to some extent comprises a molding composition comprising at least 40% by weight of a polyamide whose monomer units contain an average of at least 8 carbon atoms, and b) a part comprising another molding composition.
