In a nozzle pressing and contacting process, a mold clamping process, and an injection process in an injection molding operation, a movable side, such as constituting a nozzle portion or screw of an injection apparatus, or a movable mold of a molding apparatus, is moved towards and contacted with a stationary side, such as constituting a mold or molding machine, or a stationary mold under a speed controlled condition. When the movable side approaches the stationary side, the pressure acting on the stationary side is measured and when the measured pressure reaches a predetermined set pressure, the speed control is switched to a pressure control to accurately and smoothly bring the movable side into contact with the stationary side.
