Abstract

A method for producing a honeycomb body having a honeycomb structure disposed in a housing, includes at least forming a honeycomb structure, inserting the honeycomb structure into a housing, carrying out a heat treatment operation on the honeycomb structure having the housing, contacting outer regions with a molding, at least during the inserting step or the heat treatment step, and reproducing a desired outer contour of the housing with contact faces of the molding. A molding and an exhaust gas treatment unit produced with a thin housing in a dimensionally accurate manner, are also provided.
