Document Type and Number:
Japanese Patent JP6620082
Kind Code:
B2
Abstract:
A manufacturing method of a honeycomb structure include a forming step of extruding a kneaded material including a forming raw material by use of a horizontal forming machine include a forming die in which latticed slits are formed in a kneaded material discharge surface, to obtain a round pillar-shaped honeycomb formed body having latticed partition walls; and a firing step of firing the obtained honeycomb formed body to prepare the honeycomb structure. In the forming step, there is used the forming die in which there are formed the slits different in lattice shape between a central portion and a circumferential portion in the kneaded material discharge surface, and the forming die is disposed in an orientation in which an inclination of one row of the latticed slits formed in the central portion is within an angle of ±10° to a vertical direction, to extrude the kneaded material in a horizontal direction.
