Application of Wire During the Manufacturing Process of Ferrule |
|
We will explain how to manufacture zirconia ferrule and metal ferrule which use wire as ferrule parts. |
| (1) Zirconia Ferrule |
|
- Etch Process
- Ultra precision piano wire (±0.1µm tolerance) is used for making tapered wire for processing ferrule inside diameter.
- Processing inside diameter
- Etching is a process causing piano wire to corrode and making taper.
Polishing inside diameter of ferrule to make it fit to the diameter of optic fiber. First you set a ferrule fixed to a pipe with metal fixed vessel to a machine. Rotating at high velocities, process the inside diameter of ferrule with etching wire and polishing powder.

| (2) Metal Ferrule |
|
Electroforming (a process applying electrocoat by electrolytic process to produce metal around a core wire of same diameter with optic fiber, and remove the core wire) has no center core process that allows high hole diameter precision and circularity. Also in this process, multi core can be made by increasing a number of core wire and miniaturization of diameter can be achieved by controlling electrotyping time. SUS304 hard wire is used for the core wire. High degree of precision is required as zirconia ferrule and smoothness of the surface after the electroforming process is needed. |
