Performance And Parameters: Used to blow film of low-pressure polythene,products are widely applided to synthetic film and packing film,agricultural purposed film,packing of textiles, clothes and so on,frequency converter is used in main motor to improve steadiness of speed regulating and reduce consumption of electricity as well,screw and barrel are made of 38CrMoAL,processed with nitrogen,frame of draw machine is of lifting style to insure best freezing effect no matter which size of film is blown. Torating head of machine:keep film even in thickness,rolling portion is flat and even,especially applicable to films for composition and printing MODELTL-A45TL-A50TL-A55TL-A60TL-A65TL-A75TL-A90TL-A105Diameter of screw45mm50mm55m60mm65mm75mm90mm105mmScrew L/D Ratio28:01:0028:01:0028:01:0028:01:0028:01:0028:01:0028:01:0028:01:00Reduced diameter of film100-500mm100-600mm200-800mm300-1000mm400-1500mm700-1500mm1200-2000mm1500-2500mmSingle-face thickness of film0.008-0.06mm0.008-0.06mm0.008-0.06mm0.008-0.06mm0.008-0.06mm0.008-0.06mm0.008-0.06mm0.01-0.1mmMax.output15-30kg/h20-40kg/h25-50kg/h40-70kg/h45-75kg/h60-85kg/h80-100kg/h100-150kg/hPower of main motor7.5kw11kw11-15kw15-18.5kw18.5-22kw32-37kw37-45kw55-75kwPower of traction motor0.75kw0.75kw0.75kw1.1kw1.5kw1.5kw2.2kw3kwHeating power13kw13kw13kw18kw23kw25kw27kw32kwOutline (LXWXH)5.0x2.1x3.5m5.5x2.1x3.8m5.5x2.1x3.8m6.0x2.3x4.2m6.5x2.3x4.5m7.5x2.8x5.2m9.0x3.5x8.0m9.5x4.2x8.5mWeight1.5T1.7T1.8T2.2T2.5T5T6T8T
