ABSTRACT:
A pipe die for an underwater pelletizer is provided in which a nozzle plate is provided on the surface of a pipe die, the nozzle plate having a hole coaxially with and of the same diameter as a pipe of the pipe die. The nozzle plate is made of a material of the same quality as the die body and is provided with a hardened layer at its cutter side surface. Replacement and repair of the nozzle plate is improved by connecting the same to said die body by bonding the whole junction plane therebetween.
