APPARATUS FOR THERMOFORMING POLYMER COMPOSITE PANELS

摘要

A system and apparatus for making a plastic panel, combining: an extruder with a heated 'barrel having an inlet opening, a discharge outlet and at least one screw flight there between; a plurality of molding tools having top and bottom surfaces and sidewalls extending there between defining a cavity;a machine press with opposing top and bottom platens configured to receive a molding tool there between and apply compressive force to said top and bottom surfaces; and at least one heated vessel for receiving and storing a quantity of mixed melt, wherein the vessel has an inlet port to receive the mixed melt discharged from the barrel outlet of the extruder; a discharge port configured to deliver the mixed melt from the vessel to the cavity of the molding tool; and a metering device set to deliver the selected quantity of the mixed melt from the vessel through the discharge port.
