Injection molding device and injection molding method

Abstract

An injection molding device injects a plasticized material into a mold and performs injection molding of a molded product, the injection molding device including: a plasticizing unit configured to plasticize a material and generate the plasticized material; a first hot runner including a first flow path that communicates with the plasticizing unit and through which the plasticized material flows, a first nozzle portion that communicates with the first flow path and injects the plasticized material, and a first heater that heats the plasticized material in the first flow path; and a control unit configured to control injection of the plasticized material, in which the first nozzle portion is made of a metal material, and the control unit includes a first temperature control unit that is electrically coupled to the first heater and controls a temperature of the first heater and a second temperature control unit that is electrically coupled to the first nozzle portion and controls a temperature of the first nozzle portion by supplying a current to the first nozzle portion.
