Abstract: An injection molding system (1000) comprising: an actuator (5) having a housing (20) comprised of radial (20r, 20ri, 20ro, 20roa, 20rob, 20roc, 20rod) and axial walls (20a, 20ai, 20aue, 20ade) that form an enclosed chamber (45) containing a heat conductive chamber fluid (CF), a rotor and driver driven by electrical energy and supported within the chamber by the radial and axial walls, wherein one or more of the radial and axial walls comprise a heat conductive material that has an inner surface disposed in heat conductive contact with the heat conductive fluid (CF) contained within the enclosed chamber, an actuator tube or channel (25) disposed within the one or more of the radial and axial walls, a source (260) of heat absorptive fluid (25f) sealably interconnected to the actuator tube or channel (25).

Abstract: An injection molding apparatus (10) comprising an actuator (940, 941, 942) comprised of a driver (940dr, 941dr, 942dr) receiving electrical energy or power from an electrical drive (940d, 941d, 942d), the electrical drive (940d, 941d, 942d) comprising an interface that receives and controllably distributes electrical energy or power in controllably varied amounts during the course of an injection cycle to the driver (940dr, 941dr, 942dr), the electrical drive (940d, 941d, 942d) being housed within or by an actuator housing (940h, 941h, 942h) or being mounted on or to the housing (940h, 941h, 942h), the housing (940h, 941h, 942h) and the electrical drive (940d, 941d, 942d) being mounted on, to or in close proximity to the heated manifold (40), a cooling device (940mc, 940mc1, 940mc2, 941mc, 942mc) disposed between the heated manifold (40) and the housing (940h, 941h, 942h) adapted to substantially isolate or insulate at least the electrical drive (940d, 941d, 942d) from substantial communication with heat e

Abstract: An injection molding apparatus comprising: An actuator having a driver receiving electrical energy or power from an electrical drive, the electrical drive comprising an interface, the electrical drive being housed within or by and actuator housing or being mounted on or to the housing, the housing and the electrical drive being mounted on, to or in close proximity to the heated manifold, a cooling device disposed between the heated manifold and the housing adapted to substantially isolate or insulate at least the electrical drive from communication with heat emanating from the heated manifold or to heat sink or absorb heat communicated or communicable to the electrical drive from the heated manifold or both.
