Abstract

A granulating die for use in a hot cut method, comprising a resin discharge face provided in contact with water stream and multiple nozzles communicating with a cylinder of extruder and opening on the resin discharge face, wherein the nozzles are arranged along the circumference of a virtual circle on the resin discharge face, and wherein the resin discharge face inside the circumference with the nozzles arranged therealong is provided with a heat insulating material, and wherein multiple cartridge heaters are disposed in the vicinity of the resin discharge face so as to pass through the center of the circumference and extend outside. By this die, grains of uniform diameter can be efficiently produced while preventing any nozzle clogging.
