ABSTRACT:
Disclosed herein is a die for extruding honeycomb structural body, which comprises a die base body made of an alloy steel and a plate of a wear resistant alloy which is joined to the front face side of the die base body. In the wear resistant alloy plate are formed forming slits having a sectional profile conforming to that of a honeycomb structural body to be shaped and having a given depth from the front face of the die toward the rear face thereof, and a plurality of openings are formed independently of each other in the die base body from the rear face of the die toward the front face thereof to communicate with the forming slits. The wear resistant alloy plate may be joined to the die base body through an alloy steel plate having the same as or thinner than the thickness of the wear resistant alloy plate. A method of manufacturing such a honeycomb structural body-extruding die is also disclosed.
