Applications

This plastic extrusion line is designed for producing 16-800mm HDPE water and gas supply pipes. Pipes produced by this machine has the characteristics of moderate rigidity and strength, as well as good flexibility、anti-rot、anti-stress split and favorable hot melting. Now large diameter HDPE pipes plays a very important role in the city water and gas supply systems.
Characteristics

» The optimum spiral structure feeding throat highly improves the output of extruder.
» Accurate temperature control system ensures materials melting performance.
» Unique screw design achieves better plasticizing and high quality products.
» Precisely designed gearbox with a high torsion guarantees stable running.
» "H" shape frame to decrease vibrating of extruder.
» Advanced PLC operation system realizes synchronization and automation.
» Adopt automatic water temperature & level control and special independent filters on both vacuum and cooling tanks
