Claim Text:
1. A hot-runner system, comprising: a melt flow modular assembly having a gate melt flow control apparatus to regulate the flow of material through the melt flow modular assembly, said gate melt flow control apparatus including a valve member movable between a first position in which flow through the melt flow modular assembly is permitted and a second position in which flow is prevented; an actuator assembly coupled to the gate melt flow control apparatus to effect movement of said valve member, said actuator assembly including: an electrical conductor and a magnetic assembly, said coil and magnetic assembly being slidable relative to one another in response to current flowing in said conductor; a controller to regulate a current supplied to the conductor and thereby modulate the force generated between said conductor and magnetic assembly, one of the electric conductor and the magnetic assembly being coupled to the gate melt flow control apparatus to effect movement of the valve member between said first position and said second position in response to current supplied to said conductor and a retractable locking assembly configured to engage the valve member to inhibit movement thereof, and, upon retraction, to release the valve member to permit movement thereof.
