  • Patent number: 10144165
    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.
    Type: Grant

  • Patent number: 9738016
    Abstract: A method of injection molding of plastic materials into a cavity of a mold with a molding apparatus including a distributor of the pressurized fluid plastic material connected to at least one injector having a pin valve displaceable between a fully closed position and an open position. The method includes a filling step following displacement of the pin valve from the fully closed position to the open position, a packing step of the pressurized plastic material keeping the pin valve in the open position, and a step of displacement and maintenance of the pin valve in at least one partially closed intermediate position prior to its complete closure.
