AN APPARATUS AND A METHOD TO PREDICT THE REMAINING USEFUL LIFE OF A PLASTICIZING SCREW

A method to predict the remaining useful life of a plasticizing screw for an injection molding machine is provided. The method comprises: creating an energy-pressure ratio distribution estimate for normal operation of the screw for a mold; creating a temporally local energy-pressure ratio distributi...

Zusammenfassung:A method to predict the remaining useful life of a plasticizing screw for an injection molding machine is provided. The method comprises: creating an energy-pressure ratio distribution estimate for normal operation of the screw for a mold; creating a temporally local energy-pressure ratio distribution estimate from real time data for the screw for the mold; comparing the local distribution with the distribution for normal operation; and generating an alert if the comparison of the two distributions predicts that the remaining useful life is negligible.
