PURPOSE: A high-frequency induction melting resin injection system is provided to perform integrated control manually, automatically, or semi-automatically by the temperature or time control of an injection nozzle temperature controller. CONSTITUTION: An induction coil unit(21) covers the outer periphery of an injection nozzle(20). A high-frequency power supply unit(220) supplies high-frequency power to the induction coil unit to heat the runner of the injection nozzle by the electromagnetic force of an induction coil. A temperature controller(211) outputs an atmosphere temperature control signal to the high-frequency power supply unit so that the runner is heated and maintained at a preset atmosphere temperature before the operation of a melting resin injection machine(100). The temperature controller outputs an operation temperature control signal to the high-frequency power supply unit so that the runner is heated from the atmosphere temperature to a preset operation temperature after the operation of the melting resin injection machine.
