Woven Bag Making Machinery
Electromagnetic dynamic plastic extruding flat film stretching unit uses touching computer screen and PLC micro-processor to concentrate control, which is matched with the world first patent technology, made of electromagnetic dynamic plastic extruder, automatic belt filter changing system, high efficient hot bellows, seven-roller towing design finalizing machine and uniform moment magnetic induction winding machine. It has the performance of high speed, smooth running, sophisticated technology, reliable control and convenient operation. Compared with the traditional ones, it has the features of low power consumption (up to 40%), wide flexibility (high infilling quantity), good fiber cylinder forming quality, which is usable to improve the products' tensile strength in length and breadth, transparency and cost reduction.

The winder is mainly used for thread winding with a uniquely built construction. The machinery driving method is rational with advanced, tensile control and high winding speed which will provide you with the optimum winding effects.

Woven Bag Making Machinery Features:
1) Maximum linear speed of the winding: 280m/min
2) Maximum diameter of the winding cylinder: 160mm
3) Size for the winding pipe: φ38 (inner) x φ41 (outer) x φ230 (L)mm,
38 (inner) x φ41 (outer) x φ270 (L)mm

Electromagnetic dynamic plastic extruding machine is based on the electromagnetic dynamic plastic extruding technology invented by Prof, Jinping Qu of South China university of technology. The technology has obtained P.R.C. patent, United States patent, European economic community patent and patents of other countries. The machine adopts the way of direct transportation and introduce the mechanical vibration field which induced by an electromagnetic field into the whole plasticating and extruding process. Compared with the traditional ones, it has the advantages of small volume (reduced by 50%), low power consumption, no oil pollution (more than 40%), low noise, wide adaptability to materials, excellent ability of plasticizing blending. The machine is usable to improve the products' tensile strength in length and breadth, high transparency and cost reduction.
