Claim 25:
26. An injection molding system (1000) comprising an injection molding machine (500) that injects a flow of injection fluid (400) to a heated manifold (300) that distributes the injection fluid (400) to a flow channel that delivers the injection fluid to a gate (70) of a mold cavity (80), the injection molding system (1000) further comprising:
an actuator (5) comprised of a rotor (250) having a drive axis (Y) and a driver (100, 200) interconnected to the rotor (250) adapted to drive the rotor around the drive axis (Y),
a linear travel converter (15) interconnected between the rotor (250) and a valve pin (800) in an arrangement that converts rotation movement of the rotor to linear movement (XX) of the valve pin (800),
a heated manifold (300) that generates manifold heat,
the linear travel converter (15) comprising a converter housing (120) comprised of one or more converter walls (120r, 120rb, 120rc, 120ri, 120ro, 120a) forming a converter chamber (145) comprised of:
a first unitary converter body (120r, 120a, 120ri, 120ai) comprised of a heat conductive material having an inner surface (120ris, 120ais, 120riis, 120aiis) disposed in intimate heat conductive contact with an interior space (145s) of the converter chamber (145) and,
a second unitary converter body (20ro, 20ao) comprised of a heat conductive material that has an inner surface (120rois, 120aois) in intimate heat conductive contact or communication with a heat communicating surface (120rihcs, 120aihcs) of the first unitary converter body (120ri, 120ai) or of one or more intermediate unitary converter bodies that are comprised of a heat conductive material.
