Essential Equipment In Fiber Secondary Coating Line Operations
This secondary coating stage is critical, giving drawn optical fiber its final diameter as well as mechanical strength. This line prepares the fiber for stranding together with cabling. A well-tuned fiber secondary coating line controls coating thickness, adhesion, and surface quality. This line protects the glass during handling.
Producers aiming for high-yield, fast-cycle fiber optic cable line output must match material, tension, together with curing systems to process requirements.
High-speed secondary coating processes rely on synchronized pay-off, coating heads, and UV ovens. Modern systems achieve high production rates while minimizing excess loss. Precise tension control at pay-off and winder stages prevents microbends and ensures consistent coating thickness across long runs.
Single together with dual layer coating applications meet different market needs. Single-layer setups deliver basic mechanical protection and a simple optical fiber cable manufacturing machine footprint. Dual-layer lines combine a harder inner layer featuring a softer outer layer to improve microbend resistance and stripability. That helps when fibers are prepared for connectorization.
Temperature control and curing systems are critical to final fiber performance. Multi-zone heaters and Omron PID controllers guide screw/barrel extruders to stable melt flow for LSZH or PVC compounds. UV curing ovens and water trough cooling stabilize the coating profile and reduce variation in excess loss; targets for high-quality single-mode fiber often aim for ≤0.2 dB/km at 1550 nm after extrusion.
Key components from trusted suppliers improve uptime and precision in an optical fiber cable production machine. Extruders such as 50×25 models, screws and barrels from Jinhu, and bearings from NSK are common. Motors from Dongguan Motor, inverters by Shenzhen Inovance, and PLC/HMI platforms from Siemens or Omron provide robust control and monitoring for continuous runs.
