Classification: CPC B | IPC B

Claim 10:
11. A method comprising:
sending to a controller a first signal generated by an injection molding machine that is indicative of a start of injection or a position of a screw barrel during a first injection cycle in an injection molding system,
transmitting from the controller to a downstream actuator a gate open signal at a predetermined open gate target time (X) based on the first signal;
initiating withdrawal movement of an interconnected downstream valve pin from a downstream gate via the downstream actuator;
detecting actual withdrawal movement of the downstream valve pin from the downstream gate at an actual gate open time (A) via a position sensor
transmitting a signal indicative of the actual gate open time (A) to the controller;
automatically generating an automatic adjusted instruction time (X′) via the controller based on the difference between the actual gate open time (A) and the predetermined open gate target time (X), for use in a subsequent cycle,
forming a first one or more parts or objects within a one or more mold cavities during the first injection cycle,
instructing via the controller the valve pins on the subsequent injection cycle to open at an overall adjusted instruction time (X″) that includes or accounts for the automatic adjusted instruction time (X′).
