Abstract
An injection molding apparatus is described. It comprises a press equipped with a screw for generating molten material, and a signal generator for generating a control signal adapted for a plurality of directional valves so that they can regulate the movement of one or more actuators adapted for controlling the movement of one or more shutters which regulate a flow of molten material to the mold. There is a signal converter connected between the press and the mold for converting the signal emitted by the generator into a signal adapted for activating one or more electric actuators, wherein the signal converter is external to the press and the mold.

Injection molding apparatus comprising:
- a press equipped with
- a screw for generating molten material for injection into a mold, and
- a signal generator for generating a control signal adapted for a plurality of directional valves so that they can regulate the movement of one or more actuators adapted for controlling the movement of one or more shutters which regulate a flow of molten material to the mold,
- a signal converter connected between the press and the mold for converting the signal emitted by the generator into a signal adapted for activating one or more electric actuators mounted in the mold to operate a shutter capable of regulating the flow of molten material from a nozzle toward the mold,
- wherein the signal converter is external to the press and the mold.
