The die head is a double helix co extrusion structure, and is specially designed for online double wall expansion.
The large screen LCD human-machine interface system adopts data bus technology to achieve monitoring and management of the entire production process;
The corrugated pipe production line consists of single/twin screw extruders, forming machines, modules, air/water cooling devices, meters, and rewinding machines, which can be used for various specifications of corrugated pipes;
The use of specially designed screws and molds not only ensures the convenience and reliability of mold replacement, but also solves the problem of easy wear of machine barrel screws. The production line has fast speed, stable operation, simple control, and convenient operation;
This molding machine has a closed structure and can be vacuum formed. The molding module works back and forth in a fully enclosed molding track, which adopts a sandwich design. There is no connection between modules, which shortens the time for module replacement and maintains fast production speed;

200mm-800mm HDPE Double Wall Corrugated Pipe Production Line (Vertical)
Yili Machinery is a manufacturer of large-scale corrugated pipe extrusion production lines. The PE/PP large-diameter corrugated pipe production line provided by Yili can produce pipes with diameters ranging from 200mm to 1200mm. Manufacturing from single wall corrugated pipes to double wall corrugated pipes, and even pipes with three or more layers. The entire production line is composed of a main extruder, which is suitable for both single screw and twin-screw extruders. After the extruder, it enters the molding machine, followed by module molding, traction machine, cooling water tank, cutting machine, and stacking rack for matching use. The entire production line is centrally controlled by a PLC control system. The final product is a 200mm to 1200mm corrugated pipe, used in road construction and civil engineering for sewers, drainage pipes, water pipelines, agricultural irrigation drainage, inspection wells, and other applications
