This fiber secondary coating line is used for extruding 1~12/24 core optical fiber loose tube, the jacketing material is PBT, loose tube is round and smooth surface, its dimeter is uniform.

A. The optical fiber pay-off is the motorzed pay-off device, the tension of the pay-off line is stable and reliable, and the tension is adjustable.

B. The extruder adopts special screw, which has good extrusion linearity and high extrusion efficiency.

C Jelly filling device has professional de-bubble effect, euipped with precision metering pump and a precision weighing device to ensure timely replenishment of ointment.

D·Take-up is double reels automatic changed without deceleration, and high production efficiency.

E. International industrial computer technology control system with high degree of automation, it can be linked with MES, ERP systems, real time tracking and managing production..

F .The main control systems and components are international famous brands, and the production line has high stability and reliability.
