To provide an injection molding machine, an injection molding system and an injection control method, capable of suppressing occurrence of a defective appearance, and molding a resin with an appropriate mold clamping force.SOLUTION: The injection molding machine according to the present embodiment includes an injection device for injecting a molding material into a cavity between a first mold and a second mold by moving a screw in a barrel, and a control unit for calculating a moving speed of the screw or a flow rate of the molding material to be injected, based on a passage area of the molding material at a gate through which the molding material passes into the cavity that is provided in at least one of the first mold and the second mold. The injection device moves the screw at the moving speed or injects the molding material at the flow rate.SELECTED DRAWING: Figure 2 【課題】外観不良の発生を抑制することができ、かつ、適切な型締力で樹脂を成形することができる射出成形機、射出成形システムおよび射出制御方法を提供する。【解決手段】本実施形態による射出成形機は、バレル内でスクリュを移動させることによって、第１金型と第２金型との間のキャビティ内に成形材料を射出する射出装置と、第１金型および第２金型の少なくとも一方に設けられキャビティに成形材料を通過させるゲートにおける成形材料の通過面積に基づいて、スクリュの移動速度または射出される成形材料の流量を演算する制御部と、を備え、射出装置は、移動速度でスクリュを移動させ、または、流量で成形材料を射出する。【選択図】図２
