= METHODS FOR HEATING A HOT RUNNER OF AN INJECTION MOLDING SYSTEM =

'''Abstract''':
an injection molding system is disclosed. the injection molding system includes: a mold; a hot runner including: a manifold; one or more injection nozzles coupled to the manifold; a plurality of heaters in thermal contact with the manifold and the one or more injection nozzles, the heaters being arranged into one or more defined heating zones within the hot runner; and at least one temperature sensor associated with each heating zone, and a system controller coupled to the plurality of heaters, the system controller being configured to: for each heating zone: determine a setpoint temperature associated with the heating zone; obtain, via a temperature sensor, measurement of a current local temperature of the heating zone; determine a control gain value associated with the heating zone; and compute a predicted heating time for the heating zone based on the setpoint temperature, the current local temperature, and the control gain value, determine a heating schedule for the hot runner based on the predicted heating times for the heating zones; and operate the plurality of heaters in accordance with the heating schedule.
