Abstract: In order to improve the consistency of molded products as viscosity shifts throughout a run, a controller of an injection molding machine executes a calibration cycle in accordance with a mold cycle. The controller analyzes a plurality of sensed melt pressure values during the calibration cycle to determine one or more calibration metrics. The controller then uses the calibration metrics when executing each mold cycle of the run. More particularly, during each mold cycle of the run, the controller detects a plurality of sensed melt pressures prior to and during a fill phase of the mold cycle and compares the plurality of sensed melt pressures to the one or more calibration metrics to predict cavity pressure for a pack and hold phase of the mold cycle. The controller then adjusts a set point pressure for the pack and hold phase based on the predicted cavity pressure.

Abstract: Systems and approaches for controlling an injection molding machine having a mold forming a mold cavity include feeding a molten polymer into a barrel containing a screw disposed in a first position, advancing the screw a first instance, from the first position to a second position, to inject the molten polymer into the mold cavity to form a molded part, and ejecting a first molded part or a first set of molded parts from the mold cavity. Further, the screw is advanced a second instance, from the second position to a third position, to inject the molten polymer into the mold cavity to form an additional molded part. A second molded part or a second set of molded parts is ejected from the mold cavity. After the second advancing instance, a recovery profile is commenced in which the screw is returned to the first position.

Abstract: A method of monitoring and controlling a sequential valve gate molding apparatus in an injection molding or other molding process is disclosed. The method includes creating a target strain profile, receiving a deviation limit, receiving a change in strain relating to a first valve gate from a first strain gauge, identifying whether a deviation exists from a first portion of the target strain profile based on the output from the first strain gauge, determining whether any existing deviation exceeds the deviation limit, and adjusting the position of a first valve gate pin in the first valve gate if it does. The method may further include control of subsequent valve gates. Multiple strain gauges may be used to control a single valve gate, and/or each strain gauge may control more than one valve gate.
