YF Series PVC profile production line is mainly used in PVC door & window profile,wide door plate,window plate, extrusion of multi-holes pipe for passing through lines (four holes,six holes,seven holes,nine holes etc.) For different sectional surface and molds different specifications of twin parallel (conical) screws extruder can be chosen together with corresponding vacuum calibrating table,haul-off unit,cutting unit,tilter,etc. Capacity of extruder can be optionally chosen from 60-700kg/h.The haul-off unit has applied unique lift technique of our co.lts work is stable,its reliability is good,its pulling force is large.Vacuum setting has applied special enlarged vortex cooling system which is good for cooling and calibrating so as to meet demand of high speed extruding.Movement speed and drawing speed of cutting machine keep synchronous .All movements are controlled by imported PLC,the design is reasonable,the operation is stable,it can conduct automatic cutting with fixed length.Po
