EMISSIONS TREATMENT COMPONENTS AND PROCESSES FOR THEIR MANUFACTURE
In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises, following the firing, injecting a mixture of a mastic component and a particulate metal component from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of the lengths thereof while maintaining all of the walls of the ceramic unit, and curing the injected material to render the injected material solid.
