Product Specification

HDPE PP Double Wall Corrugated Pipe Production Line  With Plastic Extruder

The DWCP series high-speed corrugated pipe forming machine adopts a closed water-cooled structure, and the mold base drives the left and right modules to move within the closed curve. The mold base adopts a gear dynamic structure, which has the advantages of automatic compensation for mechanical wear, smooth operation, low noise, long service life, and high synchronization. The unique design of the circulating water circuit has high reliability, good cooling effect, and low water impact in the pipeline, which improves the reliability of continuous production of pipes and ensures the surface forming quality of pipes.
