A screw-moving assembly () for a screw assembly (), the screw-moving assembly () comprising: a screw-moving actuator (); and a bias-adjustment mechanism (); wherein the screw-moving actuator () and the bias-adjustment mechanism () are configured to connect to the screw assembly (); the screw-moving actuator () is configured to transmit, in use, a screw-translation force () to a longitudinal central axis () of the screw assembly (); and the bias-adjustment mechanism () is configured to transmit, in use, a biasing force () to the longitudinal central axis () of the screw assembly ().

Screw-moving assembly including screw-moving actuator and bias-adjustment mechanism

An extruder unit () for an injection molding system () includes a piston (), slidably located within a piston chamber (), and is movable between a retracted position and an extended position. The piston () is further adapted to rotatably mount a screw (). A motor assembly () is mounted to the piston housing () and operable to rotate the screw (). The piston () is translated by a hybrid injection actuator (), the hybrid injection actuator () including: a drive unit () operable to move the piston () between the retracted position and the extended position; and a gas pressure unit (), operable to provide a boosting force to the piston (), thereby urging the piston () towards the extended position.
