HDPE plastic pipe extrusion line for large diameter features: 

 High speed, high efficiency extrusion single screw extruder is specially designed for extruding PE etc. material, equipped with the lower noise, high speed and hard gear reducer. The Special grooved feeding bush with water cooling system results in increasing compression and filling factors. Specialized screw designs for high output, low melting temperature, good plasticization effection, lower energy consumption. 
Spiral diffluence type extrusion die is specially designed for PE extrusion. Unique design of low-pressure inclined flow passage spiral/lattice basket die head, ensures low temperature and high plasticizing extrusion of PE pipes; Special designed die core spiral temperature control, ensures the performance of PE pipes; Multi-layer co-extrusion die offers the advantages of low cost and flexibility of layer structure with different material. it features in easy adjustment and even extrusion, ensures that melting pressure and flux are uniformity, the surface of pipe is smooth and shapely.
