Multiple sensor resin delivery method for optimizing vacuum pump operation

System and method for turbomachinery preventive maintenance and root cause failure determination

Apparatus and method for drying thermoplastic resin prior to molding into plastic parts comprises a continuous loop liquid circuit for furnishing liquid at a prescribed temperature to a mold in which the plastic parts are fabricated; a continuous loop air circuit for passing heated dry air through a hopper containing the thermoplastic resin thereby drying the thermoplastic resin to a prescribed level of dryness; and a coupling thermally connecting the two circuits for heat transfer from the liquid to the drying air; the liquid is selected from the group comprising water and ethylene glycol; microprocessor control facilitates generation and retention of custom water temperature and resin dryness/temperature optionally based on machine learning principles.
