Abstract

The invention relates to a method for linking a first plastic component (6) with a second plastic component (9). According to the inventive method, the first component (6) is introduced into an injection mold with at least one connecting section (12) at which the link with the second component (9) is to be established. The second component (9) is formed by injection-molding plastic material onto the connecting section. A surface of the connecting section (12) is at least partially covered by the plastic material of the second component (9). At least one of the components may consist of a plastic material that requires only a relatively narrow temperature range to be moldable in the molten state. At least one binder body is formed at the surface intended to be covered by the injection-molded plastic material which binder is firmly linked with the surface. Said binder melts when contacted with the heat energy of the injection-molded plastic material and fuses with the injection-molded plastic.
