Abstract
In a method for manufacturing a mold of a metal hot-runner injection molding machine, a temperature gradient of metal disposed in a nozzle between a heating device of the nozzle and a tip of the nozzle is measured. Then, an area in the nozzle is selected based on the measurement of the temperature gradient such that the metal in the nozzle upon a mold opening has a temperature at which a solidified condition of the metal can be stably maintained, where the temperature is close to a melting temperature of the metal. A gate cut portion is determined in the area.
