Single screw extruders especially used for polyolefine material possess characteristic of high extrusion speed, high plasticizing speed.The special detachment type mixing screw and the spiral structure die and  reasonable channel are applicable to produce pipes withsmooth inside and outside face. Special design forming diameter cooling type: produce range 50-200mm，produce speed is upto 0.6- 1.5m/min.

Standard design pipes die 
Spiral distribution Spiral distribution type shunting body, large space of    
flows,  ensure the melt has enough time to stay. 
Excellent design of low melting temperature, internal stress of pipes is  
small, inside and outside has smooth surface. 
High flexibility,apply to all of the polyolefin materials, extrude two layers,  
three layers of different specifications and usage of spiral enhanced pipes.
The optimization design of the copper spiral forming diameter entry point has 
advance cooling device and strong absorption vacuum device, applicable to  
pipes of high-speed extrusion.
Special design of spray head bring high effective spray cooling.
Longitudinal moving motor regulation, up and down, left and right can realize 
three-dimensional adjustment.
Use stainless steel to produce box.
High efficiency water pump and special spray head bring high effective spray
cooling.
