Abstract

See full text

A method for plugging a subset of cells of a honeycomb structure that includes: covering a first end face of the honeycomb structure with a mask that comprises a body and a plurality of openings, wherein the plurality of openings of the mask is coincident with a plurality of cells of the honeycomb structure; providing a plenum, a movable plunger and a flow plate; positioning a cylinder between the honeycomb structure and the plenum; dispensing a plugging material into the plenum; moving the plunger toward the flow plate with a force to push the plugging material through the flow plate into the cylinder, the moving generating a pressure in the plenum and the cylinder that forces the plugging material through the mask into the plurality of cells of the honeycomb structure to a predetermined depth; and determining the pressure within the cylinder during the moving of the plunger.
