Abstract
An injection molding system including a nozzle member (18) or a valve pin (80) having a tip end (21) wherein the nozzle member (18) or valve pin (80) is adapted to be controllably rotatable around a longitudinal rotation axis (A) to enable an exit aperture (20) of the nozzle or the tip end of the pin to interface with a cavity entrance aperture (30) to controllably vary or adjust size (SP1, SP2) of the cross sectional area (CA) of a gate aperture (50) according to degree of rotation (R) of the nozzle or valve pin around the rotation axis (A).
