Abstract

A method for manufacturing exhaust gas ducting devices provides each device with an outer housing having an insert clamped therein, wherein the insert comprises a substrate traversed by exhaust gas, and an elastic compensating element surrounding the substrate. The method includes spreading each individual compensating element on a base and deforming the compensating element substantially vertical to the base by exerting a pressure such that the entire compensating element is subjected to a full-surface load. Then a setpoint deformation of the compensating element is determined, which is necessary to achieve a specified setpoint pressure. The method further includes determining at least one parameter of the substrate individually, placing the compensating element around the substrate, and mounting the insert thus obtained in an outer housing having inside dimensions that correspond to outside dimensions of the insert with the determined setpoint deformation.
