A method for producing a stable adhesion promoters free metal - plastic - composite component, as well as metal - plastics composite structural part

摘要

A method for producing a stable, adhesion promoters free metal - plastic - composite part 1 comprises the following steps:– Providing a metal part 2,– Processing of the surface of the metal part 2, to which the plastic part 4 is to be connected, by forming undercut clamping structures 5 and– Injection molding of plastic to one or more of the machined surfaces 3 or surface portions of the metal part 2 in a plastic master mold tool for forming the plastic part 4 under conditions that the original mold tool into the plastic material is plasticized plastic material is introduced into the undercut clamping structures 5 penetrates and after cooling of the plastic or of the metal - plastic - composite component 1 is fixed positively therein.A metal - plastic - composite component comprises a metal part 2, whose surface 3, to which the plastic part 4 is connected, undercut clamping structures 5 as well as a plastic part 4 which, by means of positive engagement in the clamping structures 5 at least in a direction transverse to the contact surface between the metal part 2 and the plastic part 4 in a play-free manner to the metal part 2 by means of an original shaping process, which are constructed in a form is fixed thereto.
