HDPE - PPR Pipe Extrusion Lines
HDPE-PPR Pipe Extrusion Lines
Plastech’s singe screw extruders are for extrusion of polyolefin (HDPE, HDPE PLB Ducting, PP, PP-R & LLDPE, LDPE) pipes. The extruders with screw diameters 16 mm to 400 mm are available for output range 100 kg/hr to 500 kg/hr.
This field proven design of energy efficient extruders comes with a combination of barrier screw and grooved feed bush results into optimum performance. Thus, resulting into a high-quality PE pipe which can be used for wide range of processing applications.
Features
- Energy-efficient extruder (one electrical unit delivering 3-4 kgs outputs)
- Provides excellent linearity of outputs
- Long screw designs with L/D ratio of 36:1 for excellent melt homogeneity
- 300 kg/hr pipe output with 45 mm extruder & 500 kg/hr with 60 mm extruders
- Versatile screw designed for PE & PP random co-polymer
- Direct coupled gearbox design ensures minimum transmission loss & compact layout
- Wear-resistant coating guarantees long screw life
- Grooved feed design extruder for highest efficiency
Unique Advantages
- Higher productivity compared to conventional design
- Uniform melt temperature
- Reduced power consumption (one electrical unit delivering up to 3 kgs to 4 kgs outputs)
- Wide range of processing applications due to longer L/D ratio
- Superior physical properties of end product
