12/238 Optic-fiber secondary coating line
Application:
The optic-fiber secondary coating line is mainly used for extruding 2 to 12 core fiber outer diameter Ф1.5 to Ф3.0 mm fiber loose tube bundle tube and cable filling rope extrusion. Extrusion materials should be suitable for PBT, PP, PC and PE. The extrusion shape is round, uniform and smooth.
Equipment feature
