Electrically driven type injection molding method

An injection molding apparatus includes an electrically driven injection apparatus in which a screw accommodated in a heating cylinder is driven by a motor. The injection apparatus includes a pressure detection device for detecting an injection pressure of the screw and a device for detecting a stroke of the screw. Speed control is first conducted until the preset packing rate which represents that a dwell process is almost started is obtained, and the remaining injection process and the dwell process are conducted using an output of the pressure detection device. If a volume of resin in the cylinder which is required to fill the cavity is obtained beforehand, a packing rate of the molding material in the cavity is obtained by detecting the screw stroke. A packing rate which represents that the dwell process is nearly started is preset, and speed control of the screw is conducted and the resin is thereby packed at a fixed injection rate until when that preset packing rate is obtained. In the remaining injection process and the subsequent dwell process, a desired screw thrust is obtained using the output of the pressure detection device which detects the injection pressure of the screw.
