 Extruder 
Efficient single screw extruder with water-cooling force feeding system, and barrel with grooving in the feeding zone are designed to save power of main motor; Long L/D ratio and mixing head are designed to get perfect jellification and high output. 

    Die head 
Flow channel is specially treated to have better wear-resisting; spiral die head increases extrusion pressure to improve quality of pipe. 

                  Vacuum calibration table 
It adopts bronze or stainless steel calibrators; High-efficiency water-spraying cooling to ensure quality of pipes. 

       Hauling machine 
High qualified rubber block is with longer life, we dont accept blocks made by recycled materials. Hauling speed is synchronized with extruder. 

               Planetary cutting machine 
High qualified alloy steel blade; planetary cutting to get smooth edge; High cutting precision; PLC controlling.
