The injection pressure is provided by the hydraulic system of the injection system. The pressure of the hydraulic cylinder is transmitted to the plastic melt through the screw of the injection molding machine, the plastic melt enters the vertical runner, the main runner and the sub-runner of the mold through the nozzle of the injection molding machine under the pushing of the pressure and enters the mold cavity through the sprue, and the process is the injection molding process or the filling process. The pressure is present to overcome the resistance during the melt flow, or conversely, the resistance during the flow needs the pressure of the injection molding machine to counteract, to ensure that the filling process proceeds smoothly. During injection molding, the pressure at the injection nozzle of the injection molding machine is highest to overcome the flow resistance of the melt throughout the process. Thereafter, the pressure is gradually reduced along the flow length toward the front of the melt front, which is the atmospheric pressure if the cavity interior is vented well.
