Title:
METHOD OF MANUFACTURING HONEY-COMB STRUCTURE
Document Type and Number:
Japanese Patent JP2010115896
Kind Code:
A
Abstract:

To provide a method of manufacturing a honey-comb structure by which the efficiency of production can be enhanced and the yield of raw material can be improved.

In the method of manufacturing the honey-comb structure, a raw material is extrusion-molded to form a honey-comb formed body 100 having barrier walls for dividedly forming a plurality of cells which are extended from one side end surface 1 serving as a flow path of fluid to the other side end surface 2, a plurality of slits 4 are formed in parallel to the direction of extension of the cells in the honey-comb formed body 100 to form a slit-formation honey-comb formed body 110, the slit-formation honey-comb formed body 110 is burned to form a slit-formation honey-comb burned body, and a filler is filled into the slits formed on the slit-formation honey comb burned body, thereby forming buffer parts 3 in the slits 4 to obtain the honey-comb structure 120.
