Numerical Control Warp and Weft Net (Mosquito Mesh, Square Mesh) Machine has been adopted the most advanced technical in the world, and mixed our experiences in the net production.The machine has double extruders, and they control the warp and weft strand separately. The final production has features of smooth surface and equality mesh. By twice transverse and lengthways hot stretching it turns to be the square stretching net. The mechanical property has been obviously promoted. It is widely used in the decoration, safety net, insect prevention, high grade rail and many other fields.
