We aim to be a world-class company at the top of the three niche markets of electric wires and cables, FPCs, and EDM wires.

Oki Electric Cable plays an essential part in the history of telecommunications in Japan. The Meikosha company was founded as the first telecommunications instrument manufacturer in Japan in 1881. The founder’s invention of lacquercoated wires was followed by enamel wires, which were mass produced by Meikosha’s electric wire and cable division. Meikosha later changed its name Oki Company, and then Oki Electric Co., Ltd. In 1936, the electric wire and cable manufacturing department was spun off, and Oki Electric Cable Co., Ltd. was born.

Through periods of great change that followed, Oki Electric Cable sought products that customers demanded and continued to release many unique products as telecommunications industry expanded. Today, Oki Electric Cable aims to be a world-class company at the top of the three niche markets of electric wires and cables, FPCs, and EDM wires. With our business, technology, and production departments working together, we continue to make products overflowing with ideas and contribute to the realization of a bright future.

We look forward to your guidance and cooperation in the years to come.

As its basic management policy, Oki Electric Cable Group developed and works to achieve the following principles.

  • We contribute to the wide-ranging progress of society through our business.
  • We work together the limitless growth the company.
  • On the basis of independence and good faith, we expect to do right by ourselves.

Our main products: 

OS-UZ wire: 

 Compared with conventional wires, OS-UZ achieves 30% higher   cutting speed while rough cut, also improves the smoothness of   surface and positioning accuracy. 
 Special coating on the wire prevents rusting and much improves its   shelf-life.
 A newly developed manufacturing technology enables the wire to   reduce metal powder drastically compared with the conventional   wires.

OB-P wire/OB-B wire:

This wire is the basic type in the series. It is available in two types, hard (P type) and soft (B type). This wire exhibits maximum EDM performance in a general-purpose, standard grade, or other wire EDM machine.

OB-7S wire:

This type has the smallest wire diameter in the series. It uses a brass type special alloy, realizing a reduction of cost compared to expensive tungsten wire. It exhibits maximum EDM performance in a wire EDM machine intended exclusively for using fine wire for precision machining of molds for lead frames, and so on.

OB-PN wire:

This wire is not coated with paraffin. It is ideal mainly for a wire EDM machine used in combination with an AT unit made by Mitsubishi Electric. This wire provides the work material with a fine finish and also realizes superior automatic threading ability.

OB-PZN wire:

This wire is not coated with paraffin. It is ideal mainly for a wire EDM machine which has an AWF mechanism manufactured by Fanuc.
This wire provides the work material with a fine finish and also realizes superior automatic threading ability.

OS-Z wire:

This zinc-coated wire consists of brass wire electroplated with high purity zinc. The high plating accuracy realizes faster machining speed and also provides a better surface finish on the work piece.
