DIE FOR FORMING CERAMIC HONEYCOMB STRUCTURE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a for forming a ceramic honeycomb structure capable of obtaining the healthy ceramic honeycomb structure free from bending when the ceramic honeycomb structure is subjected to extrusion, and its manufacturing method. SOLUTION: The relation between the distance from the end of the forming groove of the die for forming the ceramic honeycomb structure to the center of a supply hole and the overlap length of the supply hole with the forming groove in the supply hole is set so that the absolute value of the inclination of a regression straight line subjected to linear approximation by the method of least squares is set to 0.0004 (mm/mm) or below.
