Specialized in plastic extrusion equipment, Qingdao Fengda Plastic Machinery Co., Ltd. develops fully automatic carbon spiral conduit lines for HDPE cable protection pipes. The finished COD pipes are corrosion-resistant, high-rigidity underground ducts, extensively used for laying power cables and optical fibers in urban municipal works, highway engineering, communication base construction and solar power station wiring systems. The whole production system is assembled with core processing units: extruder, forming mould, spiral copper sleeve, water cooling tank, haul-off tractor, cutting mechanism and automatic winder. Additional auxiliary machinery such as punching devices and non-woven fabric wrapping machines can be equipped according to customer needs. To achieve stable plasticizing quality, the line adopts a screw structure exclusively developed for PE and HDPE raw materials. Critical electrical components adopt internationally recognized brands, namely Omron temperature controllers, Siemens contactors and ABB frequency converters. Apart from the standard production specifications of 20–50 mm and 50–125 mm, 150-200mm.we provide personalized customization service to match different production capacity and size demands.
- SJ/33 Extruder Machine Special extruder for HDPE/PE carbon corrugated conduits. Automatic drying feeding system removes moisture; ceramic heating rings provide balanced heat distribution, reducing energy loss and keeping melt output consistent.
- Copper Core forming component for vacuum shaping. It helps produce evenly distributed corrugations and qualified ring stiffness, effectively preventing pipe collapse and broken ripples.
- Forming Machine Core forming component for vacuum shaping. It helps produce evenly distributed corrugations and qualified ring stiffness, effectively preventing pipe collapse and broken ripples.
- Pipe Traction Machine Heavy-duty caterpillar haul-off. Traction force and speed can be fine-tuned and synced with extruder to prevent elongation deformation.
- Winder Automatic winding with constant tension control. The finished coils are compact and orderly, suitable for long-distance transportation.
