What are the production pack the basis of the equipment

As we all know you pack what are the basic equipment? Please see the following for everybody introduction, I believe you will understand! 1, raw material conveying the closed-cycle conveying system, after drying didn't contact with outside air, ensure the drying effect of raw materials. 2, extruder using special screw, the screw has a unique separation and mixing effect, to ensure the material uniform plasticizing. 3, the static current machine instead of the early sink cooling facilities, the embryo under certain temperature cooling, heighten the molecular longitudinal orientation, increased the tensile strength of the finished product. 4, the nose mold design, the same mold manufacture different specifications products, improved in network device, no leakage of material. 5, winding machine adopts double location winding device, simple operation, convenient for volume change.
