Method for manufacturing formed honeycomb structure

Abstract

A method for manufacturing a formed honeycomb structure in an efficient manner which comprises the steps of: charging a material for forming a honeycomb structure 5 into a passage 22 for preform material for a honeycomb structure whose one end portion is provided with die 3 for forming a formed honeycomb structure; and extruding the charged preform material for a honeycomb structure 5 from the die 3 to form a formed honeycomb structure 10 while passing it through the passage, wherein a screen 4 for filtering foreign matters included in the preform material for a honeycomb structure 5 is disposed in the vicinity of the die 3, and wherein an operation for reduction of frictional resistances between an inner face of the passage 22 for preform material for a honeycomb structure and the preform material for a honeycomb structure 5 which passes the passage is employed.
