Injection molding machine and method of controlling the same

A method of controlling an injection molding machine including an injecting device configured to inject a material into clamped molds and a controlling unit configured to control the injecting device the method comprising controlling, by the controlling unit, based on a past speed setting of an injection speed set in past and a past speed detection result in a molding cycle performed in advance, an injection speed in an injecting process through which the injecting device injects the material into the molds, the past speed detection result being detected in past by a speed sensor configured to detect the injection speed, wherein the controlling unit controls the injection speed based on the past speed setting in a first process in the injecting process, and controls the injection speed based on the past speed detection result in a second process after the first process in the injecting process.
