METHOD OF MANUFACTURING CERAMIC HONEYCOMB MOLDED BODY

PROBLEM TO BE SOLVED: To prevent adhesion of chips of a dried residual material to a newly extruded molded body and clogging of a cell at restart after a molding machine for extrusion molding is stopped, in a method of manufacturing a ceramic honeycomb molded body for obtaining the molded body with a honeycomb structure by filling a molding material within a material flow passage of the molding machine, performing extrusion molding from a supply hole side of a molding die including a molding groove with a honeycomb structure arranged at one end of the molding machine toward the molding groove side, and then, performing cutting into a predetermined length; and to obtain a honeycomb structure reducing pressure loss when used for a catalytic converter, a filter for particulate collection and the like for exhaust gas purification. SOLUTION: In the method of manufacturing the ceramic honeycomb molded body, the molded body with the honeycomb structure is obtained by filling the molding material within the material flow passage of the molding machine, performing extrusion molding from the supply hole side of the molding die including the molding groove with the honeycomb structure arranged at one end of the molding machine toward the molding groove side, and then, performing cutting into the predetermined length. A residual material remaining on the die face on the molding groove side is removed. COPYRIGHT: (C)2011,JPO&INPIT
