Abstract
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.
