This invention relates to a control method for high speed injection molding, particularly the control method for high speed injection molding using in-mold pressure to monitor injection step, which divides the injection step into two procedure of screw control mode and in-mold pressure control mold. Under screw control mode, the advancing speed of the screw is monitored, and when the in-mold pressure reaches a predetermined value, the control mode is transferred to in-mold pressure control mode. Under this in-mold pressure control mode, the advancing hydraulic pressure is adjusted according to the variation of in-mold pressure, enabling the in-mold pressure to reach a stable value quickly. The injection molded product using this injection molding control method can achieve the high precision requirement regarding quality.
