High Speed LDPE Blown Film Extruder Machine
The machine uses LDPE or HDPE as materials, after being heated, extruded, drawn and winded, the materials become cylindrical plastic film through cutting and sealing, the cylindrical film can be made into food packaging bag, shopping bags or liner bag within woven bag, the film can be used form agriculture film, field filom and shed film after one or two side cut in the production processing, the screw and cylinder of extruder adopt 38CrMoA1A alloy steel and are done nitrogenation threatment, extruder and driving part adopts stepless speed reqgulation
The high speed LDPE blown film extruder machine details Specification:
1,The main motor adopts frequency control of motor speed to improve the speed regulating stability of main motor and save electricity
2,The screw and material barrel adopt 38 CRMOALA which has been nitrogen treated
material of screw and barrel: 38CrMoAlA Polished with Nitride Treatment
3,The traction frame adopts lifting type. No matter what size the film is, big or small, it can achieve the best effect of cooling
4,The die adopts advanced central head feeding spiral runner molding technology
5,Molding and cooling of the film adopts air blower and air ring with high-property, low air pressure, and large air volume
6,The extruder adopts corrugated screw with oblique barrier and mixing head, which assures stable and reliable performance, high output and low energy consumption
7,It adopts friction type double surface wind-up, which has improved the flatness of the film, and made the coiling structure tight. It is easier to operate. A length metering device is installed, which makes the length of the film accuracy
