METHOD OF PRODUCING HONEYCOMB STRUCTURES

摘要

A method of producing honeycomb structures comprises the steps of putting, for immersion, the end surface of a honeycomb structure (1) in a storage vessel (9) containing slurry (8), pressing it against the inner bottom surface of the storage vessel (9) to thereby force the slurry (8) into at least some of the cells (3) to form pore-sealed portions (2), taking the honeycomb structure (1) having pore-sealed portions (2), out of the storage vessel (9), thereby obtaining the honeycomb structure (1) with at least some of the cells (3) having their pores sealed, the method being characterized in that after an air layer (10) is formed in advance between the pore-sealed portions (2) and the inner bottom surface of the storage vessel (9) to once separate the two from each other, the honeycomb structure (1) formed with pore-sealed portions (2) is taken out of the storage vessel (9).
