Unit performance characteristics
1, Use of special extruder, special screw, enhance the plasticizing capacity, increase production. Using the whole machine to move, easy to adjust.
2, Three-layer composite dedicated screw head, greenhouse film and geomembrane performance, both the production of greenhouse film, but also the production of geomembrane.
3, Use of hydraulic quick replacement filter device, change the network time is short.
4, Use of foreign advanced technology, the introduction of IBC internal cooling control system and double air duct; easy to control the cooling air volume, improve the cooling effect.
5, Traction using variable frequency motor control, with pneumatic clamping mechanism, the traction and coiler can be synchronized control.
6, Winder with double-bit center coiling.
7, Unit energy consumption compared with similar domestic manufacturers can reduce 10% to 25%
Five layers of plane superimposed the advantages of Die:
Plane stacking generally uses side feed, and the melt flows on each side of the stack. The number of head layers can be arbitrarily combined, and the temperature of each layer can be controlled separately, according to the needs of different materials to control the temperature of each layer, effectively prevent the decomposition of materials.

Tension Center Roll Features:
When the film is wound, the closed-loop tension control system, including the winding diameter calculation and the taper calculation, will gradually decrease the angular velocity of the take-up roll and the external tension of the finished film roll becomes smaller and smaller as the winding diameter increases To prevent the film roll within the loose outside, tight inside and outside the same, the surface smooth.
Tension center roll with a variety of design combinations to meet different customer needs:
1, No core tension center roll: the use of reinforced paper tube and both ends of the shaft, there is no middle mandrel, finished volume direct packaging, eliminating the need to replace the core axis link, saving labor.
2, Heavy tension center roll: the use of heavy-duty inflatable core and core automatic extraction device, finished volume weight can reach 1 ton.
Extrusion mechanism structural features:
1, single screw extruder configuration large carrying capacity extruder dedicated gear box.
2, screw barrel, screw with 38CrMoAlA high quality alloy steel, nitriding hardness HV850-960; screw with double metal screw.
3, the use of cylindrical sliding hydraulic screen changer, to achieve non-stop automatic network.
4, with a pressure sensor, pressure display system, and screw speed display instrument.
5, racks die; mold lip three adjustment structure, the use of internal heating system.
6, with a base, rail, automatic walking system and die position adjustment system, die with the lower mechanical support.
7, equipped with feeding drying system.
