A dieincludes a central member, an injection hole formed from a surface of the central memberto an inside, a plurality of nozzles formed from an opposite surface of the central memberto the inside and connected to the injection hole, a heat source provided inside the central member, and a plurality of heat insulating portionsprovided inside the central member. The plurality of heat insulating portionsextend from an outer peripheral side of the central membertoward an inner side of the central memberin plan view.

Die, method of manufacturing die, extrusion apparatus, and method of manufacturing pellets

A technique of controlling a cutter-blade pressing force to be a constant force even in employment of a configuration improving a production efficiency of a pellet is provided. In a resin cutter, a controller configured to control the cutter-blade pressing force is configured to variably control each of a revolution number of a rotation shaft attached to a cutter head, a magnitude of a rotation-shaft forward force Ff and a magnitude of a rotation-shaft backward force Fb so that the cutter-blade pressing force is constant.
