HDPE double wall corrugated pipe extrusion line features:
High performance single screw extruder or twin screw extruder with special screw ensure good extrusion
Special structure die make the thickness of the interior and exterior wall even, and stable molding. In addition, the thickness of interior and exterior can be adjusted.
With special and accurate forming module; cooling air and water system guarantee the production speed fast.
With belling inline system
With special aluminum alloy mould bolck with anti-adhereing treatment, cooling air, cooling water and vacuum channel inside of mould block ensure good forming structure of pipe and speed.
Haul-off unit ensure the production stable and thickness of pipe uniform. (only for large diameter PE pipe)
Special cut-off unit with high quality alloy knife and clamp tools satisfy different cutting.
