LDPE Tube Production Line

This production line is mainly used to produce high-precision small diameter PE pipes, such as water purifier tube, liquid spray pump suction tube, and beverage conveying pipe. The production speed can reach 120m/min.

The extruder adopts specialized big L/D ratio screw for LDPE raw material which have high output, energy saving, and excellentplasticizing efect The equipped gravimetric dosing system can achieve synchronous and closed loop contra of the extruderspeed and the line speed, thereby achieving balanced pipe weight per meter, shortening start-up time, saving raw materials, and making operation more intelligent and convenient.

The specially designed small diameter pipe die mould fully considers the application and accuracy requirements of producedpipes from material selection, processing, and even surface treatment. The mould has high precision and stable extrusion pressure,providing strong guarantee for the production of high-precision small diameter pipe.

Servo driven system is adopted for tractor, which has the characteristicsof stable operation and fast response speed. The synchronous controlwith the extruder ensures the LDPE pipe maintain a constant speed,uniform force, and deformation without exceeding the tolerance during high-speed production.

Dual servo traversing system of the coiler can achieve customized requirements, including pipe coils with and without paper or

plastic drum. And a tension control system is adopted to automatically control the winding speed, perfecty matched with theproduction speed. The independent PLC control system makes it more convenient to set parameters such as pipe diameter and reel width, making the pipe arranged neatly and tidily.

Adopting Siemens PLC control system, can achieve many intelligent operation such as synchronous control between machines,separate machine control, fault diagnosts, remote controletc. At the same time, advanced online measurement and controltechnology is used, ensuring the plasticization quality and pipe accuracy under high-speed extrusion conditions.
