Abstract: A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

Abstract: Systems and approaches for controlling an injection molding machine having a mold forming a mold cavity and being controlled according to an injection cycle include obtaining a pattern for the injection cycle, operating the injection molding machine to inject a molten material into the mold cavity , and measuring a cavity pressure value of the mold cavity during the mold cycle. Upon measuring a nominal cavity pressure value, a pattern recognition portion of the injection cycle that is at least partially dependent on the obtained pattern commences where a driving force being exerted on the molten material is adjusted such that the measured cavity pressure matches the obtained pattern for the injection cycle.

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: A method and system for adjusting melt pressure in an injection molding material that allows calculating a melt pressure of a molten plastic material to be injected and based on the calculated melt pressure and a desired melt pressure adjusting operation of an injection molding machine. This control of an injection molding cycle using the method and system of plastic melt pressure determination allows production of parts of increased quality and consistency.

Abstract: Systems and approaches for controlling an injection molding machine having a first configuration and a mold forming a mold cavity and being controlled according to an injection cycle include obtaining a pattern for a portion of an injection cycle of an injection molding machine having a second configuration and operating the injection molding machine having the first configuration to inject a molten material into the mold cavity. While operating the injection molding machine having the first configuration, the obtained pattern is used to control a portion of the injection cycle.

Abstract: Systems and approaches for controlling an injection molding machine having a mold forming a mold cavity and being controlled according to an injection cycle include injecting a molten polymer into the mold cavity according to the injection cycle using a screw that moves from a first position to a second position. Upon completion of the injection cycle, a recovery profile commences where the screw is moved to the first position. Using a sensor, at least one variable is measured during the recovery profile. At least one operational parameter of the injection molding machine is adjusted based on the at least one measured variable during the recovery profile.
