A die for extruding a honeycomb structural body, which is produced by forming a lattice of slits (2) having a given depth in the front surface of the matrix (1) of the die in a shape corresponding to the geometrical shape of a honeycomb structural body to be extruded, forming a plurality of independent feed inlets (3) for a ceramic batch and communicated to the slits in the rear surface of the matrix, and forming a metal film (4) on the surface of the slits (2) by plating so that the slits (2 min ) have a given width, can be easily recovered its original given slit width by forming again a metal film on the surface of the slits by plating after the original metal film has been worn due to the abrasion by the ceramic batch. |
