 **Extruder:  Appropriate single-screw extruder (exhaust or not) or Parallel twin screw extruder should be chosen on the basis of different materials. Specially designed screw and advanced temperature controlling system ensure the good plasticization, high output and stable extruding.


 **Screen changer and mould:The quick screen changer of hydraulic system ensures the short course of screen changing without material-leakage. Reasonable structure of mould should be chosen in terms of material, whereas moulds of clothes-rack mode are widely accepted to regulate flow-distribution and guarantee even thickness of plates (sheets).

**Three-roller calendaring machine:Inclined and vertical three-roller calendaring machine should be chosen according to the thickness of the plates(sheets). Temperature controller operates separately and gap among the three rollers can be adjusted freely, and the central roller has special design of regulating angle. Both ensure the excellent calendaring effect and even thickness of plates (sheets).


**Bracket of cooling roller:Equipped with corresponding guide roller, the cooling effect is better. In addition, the edge-shearing device equipped can guarantee fixed width of plates (sheets) and quality of edge.
**Edge side cutting device online, so the side of sheet will be smooth and uniform, the cutting wastage can be reused for production
**Cutting side online crushing and recycling device, it can make the cutting wastage into small flakes.
**Haul-Off Device.
**Cutting machine:It is of length-fixed cutting with cutting precision less than 2mm and adopts alloy blade or rigid alloy saw bit to ensure the good cutting effect and constantly stable performance.


**Electricity control system:

Siemens PLC touch screen computer control, ABB contractor, ABB inverter,Temperature control table RKC or OMRON.
**Raw material mixing device and crusher.


3. Extrusion Line Characteristic:

1. Adopting the oversea advanced technology to make the optimization design with big screw L/D ratio and high production capacity.
2. To change the net by full-auto hydraulic changing net, easy and fast.
