Product Introduction
Technical Background
As a core equipment for cable, pipe, and composite material production, coating extruders have driven material advancements in construction, energy, automotive, and other industries through technological innovation. Modern extruders optimize screw structures (e.g., twin-screw design, barrier mixing sections) to achieve uniform plasticization of PVC, TPU, PA, and other materials, while supporting biodegradable materials (e.g., PLA) to meet environmental requirements.
Precision molds and temperature control are critical for coating quality. High-precision molds maintain coating thickness tolerance within ±0.03mm, while a three-stage temperature control system (electromagnetic heating + circulating water cooling) ensures precise regulation of crystallization processes, preventing thermal degradation and shrinkage. Traction and cooling systems utilize servo motor synchronization and high-pressure spray cooling, combined with real-time laser diameter gauge feedback, to maintain uniform adhesion at line speeds up to 150m/min.
For intelligence and energy efficiency, the equipment integrates PLC and IoT technologies, enabling full automation from feeding to winding, alongside remote fault diagnosis and process optimization. Electromagnetic heating reduces energy consumption by 30% compared to traditional resistive heating, with unit energy consumption as low as 15 kWh/hour when combined with waste recycling systems. Current innovations extend beyond traditional metal wire coating to include steel pipes, aluminum pipes, copper wires, and other substrates, making them ideal for high-end applications like new energy vehicle wiring and corrosion-resistant pipelines.
Structural Composition
Extruder:
- Screw and Barrel: The screw is responsible for plasticizing and extruding plastic raw materials. The barrel is usually made of high – temperature – resistant materials to withstand high – temperature and high – pressure environments.
- Motor: Drives the screw to rotate and provides the required power.
- Heating Device: Multi – stage heaters provide the required temperature control to ensure effective plasticization of plastics.
- Mold: A mold customized according to the pipe specifications is responsible for shaping the molten plastic into a pipe. The mold design affects the diameter and wall thickness of the pipe.
