Abstract
A molding method for the production of articles molded by injecting plastic material into a mold cavity by a plurality of injectors electrically sequentially actuated under an electronic control according to a cycle providing for a step for filling the mold cavity, followed by a step for packing the plastic material in the mold cavity. Each injector, regardless of both its position with respect to the mold cavity and its opening speed, is controlled in at least one of the following control modes: i) partially closing the injector from a maximum open condition to a less opened condition in the filling step, ii) setting the injector in a partially open condition and then opening the injector to a more opened condition, in the packing step.
