PROBLEM TO BE SOLVED: To perform feedback control of injection pressure, injection speed, etc., and to efficiently perform molding work by detecting pressure in a mold, position of a nozzle, etc. SOLUTION: The apex position of an injection screw provided in an injection cylinder device is detected as a nozzle position by means of a position sensor 16 and injection pressure in a mold is detected by means of a pressure sensor 17. Temperature in the mold is detected by means of a temperature sensor 18. The nozzle position which is a target of the injection screw is set by means of a position setting tool 19 and the injection pressure which is a target of a resin material is set by means of an injection pressure setting tool 20. Injection speed which is a target of the resin material is set by means of an injection speed setting tool 21. In an injection process, feed back control of the injection pressure is performed by means of a pressure control valve 14 in corrsponding to the aimed injection pressure and feed back control of the injection speed is performed by means of a flow rate control valve 15 in corrsponding to the aimed injection speed.
