This production line uses PVC powder as material to produce various sorts of the mentioned plastic profiles as profiles for doors and windows, decorative profiles, etc. As the extrusion line is optimumly designed by referring to the latest overseas technology, it bears the features of even plasticization, low cutting rate, high output, and long lifespan, etc. And it composes conical double-screw extruder, vacuum sizing platform, tractor, cutting and film coating machine and material stirring bracket,etc. The main machine is run by alternating current frequency controller or direct current controllable silicon. The temperature controlling instrument is introduced from abroad. In addition, the vacuum pump and traction engine of the auxiliary machines are quality products which can be maintained easily. If change certain screw and mould, this profiles extrusion line can directly extrude foaming profiles, and the effect is much better than that of single-screw.
