400mm HDPE Pipe Making Machine

                                       400mm HDPE Pipe Making Machine 

Dianmei Co., in short D&M,  produces PE pipe machine. It has a high output single screw extruder for PE extrusion line, adopting ultra-high torque hard face  gearbox which can endure high rotation speed and specially designed barrel screw; the output can reach a level beyond the imagination in the realization of the ideal under the premise of plasticization (equipment output limited to 3kg/kw , this equipment output can be greater than 4.5kg /kw).

HDPE Pipe Making Machine Features 

 Diameter Range: Φ400 – Φ800

1.Using high efficiency extruder designed for special HDPE pipes. The screw adopts a structure with a barrier and a mixing head. The barrel adopts a new type of slotting machine barrel. The plasticizing and mixing effects are good, and the extrusion volume is large and very stable. The screw and barrel has a special design for HDPE pipe.

2.The production line adopts spiral die head that is designed for HDPE large-diameter thick-walled pipe. The die head has the characteristics of low melt temperature, good mixing performance, low cavity pressure, and stable production. The constant temperature controller system for die head makes the melting material good pipe.

3.The line uses a proprietary technology of sizing and cooling system, using water film lubrication and water ring cooling to meet the requirements of HDPE materials, to ensure high-speed production of thick-walled pipes with stable diameter and roundness.

4.The line adopts specially designed vacuum calibration tank with multi-stage control vacuum degree to ensure the dimensional stability and roundness of HDPE and PP pipes. Extruder and Hauling-off machine adopt imported brand-name governor to control with good stability, high precision and high reliability.
5.The operation and time of the line is controlled by the PLC programmatically with good man-machine interface. All process parameters can be set and displayed through the touch screen. Special extruder for marking line can be assembled to produce national standards pipes with color marking.
