Abstract
A method for injection molding of plastic materials into a cavity of a mold by means of a molding apparatus including at least one injector having a pin valve displaceable between a fully closed position and a maximum opening position, and vice versa, in a controlled fashion in respect of its position and speed. In the opening displacement from the fully closed position to the maximum opening position, the pin valve is initially moved at a first speed and subsequently at a second speed, where the first speed is the highest opening displacement speed of the pin valve.
