In-Mold Non-Time Dependent Determination of Injection Molded Part Ejection Readiness

A non-time dependent injection molding system comprising:

• an injection molding machine comprising an injection unit and a mold forming a mold cavity, the injection unit adapted to receive and inject a molten plastic material into the mold cavity to form a molded part;
• a controller adapted to control operation of the injection molding machine;
• and
• one or more sensors coupled to the injection molding machine and the controller;
• wherein at least one of the one or more sensors is adapted to measure a non-time dependent variable of the injection molding machine and transmit the measured non-time dependent variable to the controller, wherein the controller is adapted to determine whether the measured non-time dependent variable reaches a threshold value indicative of the molded part being structurally sound and is further adapted to cause the molded part to be ejected from the mold cavity upon the measured non-time dependent variable reaching the threshold value.
