Abstract: A part-forming machine having an infrared vision inspection system and a method for verifying the presence, absence and quality of molded parts therein wherein an infrared vision system is utilized. At least one infrared sensor is used in conjunction with a part-forming machine, wherein the infrared sensor takes an image of the part and/or mold based on infrared radiation emitted by the part/mold. Based on the infrared image, the part-forming machine responds thereto by activating ejectors and reimaging the part/mold, or continuing with the next molding step.
