Features of the PE silicon core micro-duct pipe extrusion line:
1)2 high efficient Extruders are equipped, specially designed for HDPE layer and Silicon core layer. The 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.
2)Screw and barrel adopt high quality alloy steel, and treated by nitriding, polishing, and honing，with long serving life.
3)Equipped with high efficient ceramic heaters and powerful cooling fans, effectively balance the melt temperature in screw and barrel, ensure the melts inside with great plasticizing effect.
4)Extruders are intergrated controlled by PLC computer control system, sync control with the downstream equippment.
1)The HDPE micro-duct extrusion line is adopting high quality mold steel as the die head raw material. Special surface treatment to extend the die head’s serving time.
2)The die head is designed and developed by our-own technical team. Adopting own-patented multi-layer composite co-extrusion technology, combined with imported high-precision CNC processing machines, the die head and extruding tools are with high precision, and can produce pipe diameters of 5-20mm.
3)The reasonable die head structure avoids heat accumulation during high-speed production and ensures the smooth surface and tube embryo is uniform when it’s extruded.
1)Gravimeter control system is a kind of closed-loop control system with extruder. It controlled by integrated PLC moulds with the whole production line.
2)Gravimeter is equipped with imported weighting sensor from Switzerland and imported SMC pneumatic component from Japan. Make sure the pipe weight per meter is stable and ensure the pipe is with high quality in high speed producing process.
3)The gravimeter can save 2-6% raw materials, meanwhile increase production capacity. Ensure there's lower raw material waste when Micro-duct extruding machine start up.
1) Special vacuum tank structure for high speed PE silicon core microduct pipe production line
2) Vacuum pressure can be monitored in real time.
3)The unique vacuum cooling system ensures that the pipe is shaped and cooled during high-speed production while saving space in the workshop for customers.
4)Automatic water input&drainage system for HDPE Silicon Duct Machine.
1)Automatic pipe coiler with double working position, auto pipe coiling, auto reel changing, servo travsering unit.
2) Special automatic pipe coiler is designed for High-Speed micro-duct extruion line, Max. Stable speed: 200m/min.
