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.
A process for manufacturing a component for an emissions treatment unit, comprising taking a ceramic unit prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure having an array of parallel, linear tubular cells extending along the length of the extrusion, the cells bounded by walls dividing adjacent cells from one another, the ceramic unit being obtained by cutting off a length of the extrusion and curing and firing the length of extrusion, the process further comprising, 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 mixture to render the injected mixture solid.
A component for an emissions control unit, comprising a ceramic unit prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure having an array of parallel, linear tubular cells extending along the length of the extrusion, the cells bounded by walls dividing adjacent cells from one another, the ceramic unit being obtained by cutting off a length of the extrusion and curing and firing the length of extrusion, the component further comprising a mixture of a mastic component and a particulate metal component injected 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, the injected mixture having been cured to render the injected mixture solid.
