Abstract:
A method of joining a first component (6) made of plastic to a second component (9) made of plastic, where the first component (6) is introduced into an injection mold with at least a connecting section where the connection to the second component (9) is to be formed, the second component (9) being produced by integral molding of plastic onto the connecting section (12) of the first component (6), one surface (13) of the connecting section (12) being wetted at least partially by the plastic of the second component (9), comprisingat least one bonding body (14) is formed on the surface (13) of the connecting section (12) which is provided for wetting by the plastic of the second component (9), said bonding body being fixedly connected to it and designed so that it melts in integral molding of the plastic of the second component (9) due to the thermal energy of the integrally molded plastic and it melts with the integrally molded plastic, whereupon the bonding body (14) is at least partially subsumed into the integrally molded plastic and becomes integrated into the integrally molded component (9); the first component is an intake manifold (6) of an intake manifold system (1) which receives the air from an air supply which is provided for combustion in the internal combustion engine and distributes it to individual combustion chambers of the internal combustion engine, and the second component is a flange (9) of the intake manifold system (1) which can be connected to the internal combustion engine; the intake manifold system (1) has a modular design, with an air distributor module (2) made of plastic which can be connected to the air supply of the internal combustion engine, with several intake manifold modules (6), each made of plastic and designed in one piece, connected at their one pipe end (7) to the air distributor module (2) and each assigned to one of the combustion chambers of the internal combustion engine, and with at least one flange module (9) made of plastic in one piece to which at least one of the intake manifold modules (6) is connected at its other pipe end (8).
