The machine using material of polypropylene & high density polyethylene, through heating extruding and drawing makes tape that is then winded for the weaving of thecircular loom. Through our many times improving , the machine can use 100% regenerated PP & PE ,powder or grain PP& HDPE to produce the tapes .The screw and cylinder of extruder are made of 38 CrMoAIA alloy steel, the hardness is over HV 950 after nitrogenation treatment. Helical gear reducer made of 20 CrMnTi Tially steel is applied to the extruder, the gears & chain wheels are made of 45# medium carbon steel and done the treatment of high frequency quench.The driving rollers are electroplated with hard Cr, tension self-controlling of winding-rollers are applied to the driving unit.. The cylinder of extruder, triton and die adopt aluminum cast heater which is endurable.
