Film Extruder Machine 1.Characteristics: It is used for blowing polypropylene (PP) and also for blowing high/low density polyethylene (HDPE, LDPE) tube which is widely used for packing food, garments, textile, daily necessities and industrial products etc. The cylinder and the screw of extruder are made of high quality alloy steel with optimum hardness and strong corrosion resistance after nitrogenization treatment. The extruder can be lifted up to 3 meters according to the technological requirements. Mode of film blowing adopts bottom blowing. The coiling device adopts torque motor to keep proper tension and make winding even and roll-changing convenient. 2.Main Technical Parameters: Model SJ-55-FM600SJ-60-FM700SJ-70-FM800Diameter of screw 55mm60mm70mmL/D ratio of screw L/D28:1L/D28:1L/D28:1Rotational speed of screw 10-100r/min10-100r/min10-100r/minPower of main motor 11kw15kw18.5kwRotational model of machine head Unilateral continuous rotationMaximum output 32kg/h38kg/h46kg/hMax. lay-out width of film 600mm700mm800mmSingle-sided thickness of film 0.01-0.10mm0.01-0.10mm0.01-0.10mmGross power 22kw28kw36kwWeight of machine 2300kg2900kg3500kgOverall dimensions (L×W×H) 4.8×2×4 M4.8×2×4 M5×22.0×4.2 M
