MOLDING DIE, HOLLOW TYPE CERAMIC MONOLITHIC CARRIER, ITS MANUFACTURING METHOD AND CATALYTIC CONVERTER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a hollow type ceramic monolithic carrier of a high isostatic strength, while a method for manufacturing the hollow type ceramic monolithic carrier at a low manufacturing cost and a molding die are provided. SOLUTION: A main body part 82 having many cells 45 surrounded by a honeycomb type bulkhead 84, a hollow hole 80 provided so as to pass through longitudinally in a central part of the main body part 82, a peripheral skin part 81 covering a peripheral surface of the main body part 82 and an inside peripheral skin part 83 covering an inside peripheral surface of the main body part 82 are provided. A bulkhead 84 positioning between a content of 1 to 10 cells from the inside peripheral skin part 83 is made a high strength part S2 of a higher strength than that of a general part P being the bulkhead 84 positioning outside that.
