Twin Screw WPC Profile Extrusion Line For Wood Plastic Composite Profiles , SJSZ-65 / 132

Description:

With special designed screw ,barrel, mould and production process ,equipped with series downstream equipment ,this can produce PE /PP/ PVC and wood-plastic composite profiles.This is a new kind of environmental freindly building material. WPC profiles is produced by mixing the plastic ,wood powder ,foam agent and other additives, after high temperature and high pressure ,the products can be used for pallets ,packing plates ,windows and door frames ,decoration panels etc.
 

Feature:
 
1.High quality; unique design; excellent manufacture;
2.Reasonable feeding technology; feed plastic and wood power(after treated) separately and correctly with avoid layering phenomenon and mass defect, because of different ratio of plastic and wood power.
3. High efficiency: Good mixing and plastering effect, fine liquidity and quickly, high efficiency.
4. Low efficiency consumption: no need of drying granulation obviously can save energy.
 

Features of Finished Product: 

1.The new plastic-wood composite is similar to wood in look, feeling and smell, but with better performance than wood.

2.Resistant to water, insects, corrosion and mildew. 
3.Ideal for applications in high moisture environments. 
4.Lightweight and durable. 
5.Superior dimensional stability. 
6.Recyclable to meet environmental protection requirements. 
7.No surface finishing is required. 
8.Same processing methods as for plastic. Suitable for mass production. 

Equipment advantages: 

1. The parallel twin screw extruder is used to mix the wood and plastic, and get good homogeneous melt 
2. It uses single screw extruder as the second stage to build the pressure to extrude the final product
3. It adopts both advantages of single screw extruder and parallel twin screw extruder
4. Wood fiber can be 65% in the WPC products due to the good mixing effect, so the cost of WPC product is low 
5.Four-step vacuum exhaust to get good exhausting and dehumidifying effect
6. If the natural moisture is less than 10%, the dryer is not needed
7. It saves investment and energy 
8. The material and screw are made from special alloy, so the service life is longer than other equipment
9. This is one step WPC extrusion technology, which saves energy 
10. The parallel twin screw extruder is of building block structure, so it can produce variety of plastic through adjusting the screw
