| abstract | METHOD AND APPARATUS FOR EXTRUDING THERMOPLASTIC MATERIAL Abstract of the Disclosure A gear pump assisted screw conveyor extrusion system utilizing a car-tridge heating device-disposed axially within the screw and having the drives for the gear pump and the screw correlated in speed to create relatively little pressure in the thermoplastic material being extruded such that relatively little mechanical working thereof occurs. The thermoplastic material is melted in the screw conveyor primarily by heat transfer from the cartridge heater and the gear pump is utilized for conveying the melted material under pressure to a subsequent work station, A relatively deep material- conveying spiral nel is provided in the screw for maximized extrusion output per revolution of the screw and minimized mechanical energy generation by the screw, A ionless mixer may be employed intermediate the screw and the work station to homogenize the melted material for reducing temperature gradients therein. The system advantageously is capable of extruding material at a substantially greater rate and a lower material temperature and with substantially increased power economy than conventional systems utilizing a high pressure, externally heated screw conveyor portion, |
