EX90Single Screw Plastic Extruder1, Uses and Application  Plastic extrusion machine is mainly used for extrusion molding of thermoplastic polymers, matching the corresponding screw, nose and auxiliary equipment to produce thin film, cable, single wire, tubing, plates, bars and other products. 2, Main structure and working principle  The machine is mainly formed by the compression system, transmission system, heating and cooling system and control system. Screw material is 38CrMoALA and is treated by nitriding whose hardness can be up to HV 700-940. Screw tubes are manufactured by 38CrMoALA after nitrogen treatment with high wear and corrosion performance. model L : D Driving power (KW) Heating power KW Cooling fan Output KG/H EX-35 30:1 7.5 6 3X0.16 20 EX-40 30:1 11 6 3X0.16 35 EX-45 30:1 15 6 3X0.25 50 EX-65 30:1 37 12 3X0.25 120 EX-75 30:1 55 16 4X0.25 160 EX-90 30:1 90 20 4X0.37 260 EX-120 30:1 132 30 5X0.37 360 EX-150 30:1 220 56 7X0.55 560 EX-180 30:1 280 70 7X0.55 760 EX-200 30:1 315 90 9X0.55 900 EX-220 30:1 450 110 11X0.55 1200 extruder, plastic extruder, extrusion machine, plastic machine, plastic machinery, single screw extruder, double-screw extruder, sheet extruder, extruder machine.
