  • In-mold non-time dependent determination of injection molded part ejection readiness
    Patent number: 11072102
    Abstract: Non-time dependent measured variables are used to effectively determine an optimal ejection time of a part from a mold cavity. A system and/or approach may first measure at least one non-time dependent variable during an injection molding cycle. The part is ready to be ejected from the mold upon the measured variable reaching a threshold value indicative of, for example, a part temperature dropping below an activation temperature.
    Type: Grant
