METHOD OF PRODUCING SEALED HONEYCOMB STRUCTURE BODY

摘要

A method of producing a sealed honeycomb structure body is performed as follows to form sealing sections: slurry (6) as the material for the sealing sections is stored in a storage container (7) such that a boundary face of the slurry (6) is flat and then that end face of a honeycomb structure body (3) which is provided with a sealing section forming mask (8) covering opening end sections of cells excluding the sealing cells (9) of the honeycomb structure body is pressed to the slurry (6) stored in the storage container (7), thereby the slurry (6) is introduced into the inside of sealing cells (9) to form the sealing sections.
