To provide a die for a granulator and a method for manufacturing the die, particularly the one which is inexpensive and improved in wear resistance, regarding the die for the granulator for pelletizing various waste such as livestock dung, woody incinerated ashes, and water supply and sewerage sludge, and the method for manufacturing the die.

The die for the granulator having a plurality of molding holes in the peripheral wall of a cylindrical body is obtained by carrying out hardening treatment after forming an electroless nickel plating layer on the surface of the cylindrical body formed using carbon steel for mechanical structure as a base material and formed with the molding holes in the peripheral wall and then subjected to heat treatment.
