Method for manufacturing composite systems made of metal and polymer shaped parts
A method for manufacturing composite systems including metal and polymer shaped parts in the form of stabilizers, bushings, axle bearings, especially in the chassis area, stops, buffers, especially for supporting arms for aggregate bearings, or sleeve bearings, especially torsion-bar shoulder bearings, is provided. With the method, at least one completely vulcanized or partially vulcanized elastomer shaped part, especially a rubber shaped part, as the polymer shaped part and at least one metal part are first prepared. The metal part and the polymer shaped part are then brought into abutment against one another, at least in parts. And, finally the metal part or at least one region of the surface on which the metal part and the polymer shaped part abut against one another, is at least temporarily exposed to at least one induction field or at least one inductive heating unit.
1. A method for manufacturing composite systems for stabilizers, bushings, axle bearings, stops, buffers, or sleeve bearings, the composite systems comprising metal and polymer shaped parts, comprising:
providing at least one partially or fully vulcanized rubber shaped part as a polymer shaped part and at least one metal part;
bringing the metal part and the polymer shaped part into abutment against one another;
at least temporarily exposing at least one region of a surface on which the metal part and the polymer shaped part abut against one another to at least one low frequency or moderate-frequency induction field of at least one inductive heating unit until a pre-determined activation or adhesion temperature of the metal part of about 200° C. or higher is reached; and,
pressing together the polymer shaped part and the metal part before and/or during and/or after exposing the metal part abutting against the polymer shaped part to the at least one low-frequency or moderate-frequency induction field, thereby bonding the polymer shaped part to the at least one metal part.
