The Optical Fibre Cables used for Telecommunications being very delicate and sensitive, it became necessary to modify the HDPE Pipes to be used as conduits for optical fibre cables. HDPE PLB duct is a modernized choice for most of the urban or city plant who has limited spaces. HDPE PLB duct extrusion line is the machine for producing HDPE PLB ducts.

| 1) | Main and auxiliary extruders are specially designed according to HDPE or silicon material processing properties. |
| 2) | Main extruder screw adopts our own designed newest structure of five-zone type for high effective plasticizing, which efficiently improve the materials plasticizing & mixing effect,and save raw materials; The barrel is equipped with high-efficiency ceramic heaters and powerful cooling fan to effectively balance the melt temperature inside even during high-speed production. |
| 3) | Auxiliary machinery for extruding silicon layer. Feeding seat is with Circulating water cooling, which can prevent the material blocking in the feed mouth. |
| 4) | PLC programmable computer control all the machine running parameters: Main/Auxiliary extruder’s current, rpm, each heating zone temp., melt pressure/temp, etc. Extruders are sync controlling with gravimeter and other downstream devices. |
| 5) | Marking line extruder can be equipped according customer's requirement. |
| 6) | The whole production line is intelligent, and easy to learn for workers. |
1)High precision Co-extrusion die head structure, which’s made of high-quality mold steel and imported high-precision equipment.
2) Suitable for producing pipes with dia: 20-90mm
3)Extruding tools can be ribbed or smooth surface according requirement.
4) A rope can be inserted while extruding process.
1)It can coil pipes with a diameter of 20-90mm, double stations, wide application range and high work efficiency.
2)Servo traversing unit arrange pipes neatly and cleanly, and the inner diameter of the reel is adjustable according customer's needs.
3)PLC computer control screen operation is convenient for working with the entire production line.
