PPR PE 3 layer co-extrusion line description：

The production line of 3-layer co extrusion PPR pipe is a new product developed by our company by introducing and absorbing foreign advanced technology. 

Characteristics of PPR 3 layer tube extruder production line ：

1. This machine is mainly used for pipe production with PPR resin as raw material. 

2. The design of slotted feeder barrel and barrier screw can improve the plasticizing effect. 

3. High extrusion rate, low melt temperature and uniform temperature. 

4. Barrier type two pole mixing, i.e. special screw for day, slotting barrel. 

5. Equipped with a new type of secondary split die, with the characteristics of low temperature and low pressure extrusion: water film sizing sleeve, to ensure the high-speed production of pipes. 

6. The production line is controlled by PLC, and PPR cold and hot water pipe production line manufacturer has good man-machine interface. 

7. The marking line can be selected to extrude to produce the pipe with color mark. 

The production line can produce PE pipe by changing mould. 

8. Random polypropylene production line is mainly used to produce pipe production line with PP-R resin as raw material, and also suitable for pipe production with PP, Pb and PE resin as raw materials. SJ-65 / 33 is used as extruder, equipped with corresponding mould, cooling device and traction device, which is used for continuous and efficient extrusion of pipes. It has the characteristics of stable quality and convenient operation.

PPR PE Pipe 3-Layer Co-extrusion Line production process
Drying of raw materials→ Extrusion molding → Vacuum sizing → Spray cooling → Haul-off → Fixed length cutting → Pipe filling and unloading
