Abstract
In a granulating die for synthetic resin, including: a plurality of nozzle holes formed in rows; a plurality of heating jackets each arranged between the rows; and a plurality of vacuum heat insulating portions formed on a surface of the granulating die, each of the vacuum heat insulating portions being arranged adjacently to one of the heating jackets, the granulating die provides the nozzle holes which are prevented from being cooled excessively by circulating water to eliminate choking of the nozzle holes to make it possible to obtain good pellets.
