UI Denshi Co., Ltd.

We have a track record and confidence in harness weight reduction technology.

We are an electronic component manufacturer founded in 1969. We mainly manufacture and sell harnesses for micro coaxial cables and optical fibers. We an extensive track record of doing business with major domestic Japanese manufacturers such as Mitsui Mining & Smelting Industrial, Yokogawa Electric, Meidensha, Nissan Motor, and Honda Motor. We have confidence in weight reduction technology. We made proposals regarding introducing optical fiber for cables, thinning cables, adopting aluminum cables, and so on, and have built up a track record. We make the best use of our original aluminum soldering technology and technology for junctions between aluminum wire and copper terminals. This includes technology that makes it possible to solder a wire onto a pattern only 0.25 mm in width by using a microscope.


Other presentation

[Company strength]
We propose aluminum harnesses, in which heavy, expensive copper wire is replaced by inexpensive aluminum wire. These products can be used in fields where weight reduction is required. We also anticipate that aluminum will be introduced to wiring in all fields as long as copper prices remain at their current level. We will advance the introduction of aluminum harnesses by providing our technology for junctions between aluminum wire and copper terminals. This is why we have put unreleased aluminum wire on sale. Aluminum wire manufacturing can be realized by the network of businesses we have established.

[Business description]
We manufacture and sell various harnesses to be used for superfine coaxial cables and optical fibers. We can process various kinds of connectors and cables. These include coaxial connectors, D-sub connectors, MIL connectors, FPC/FFC connectors, optical connectors, narrow-pitch connectors, superfine coaxial cables, hybrid cables, optical fibers, flat cables, and aluminum wires.

Electronic component manufacturing

[Strength of products/technologies]
We possess weight reduction technology. We are taking on the challenge of reducing harness weight by introducing optical fiber to cables, thinning cables, adopting aluminum cables, and so on.
Soldering technology: We possess technology power making it possible to solder wire onto a pattern of only 0.25 mm in width by using a microscope. Aluminum is considered to be a metal that cannot be soldered, but we applied our original technology to achieve aluminum soldering.
Aluminum junction technology: We can achieve junctions between aluminum wire and copper terminals, which had been regarded as being difficult. We are a unique company among SMEs because we possess such technology based on our original know-how.

[Representative's message]
We have been participating in exhibitions every year for the past five years. We participated in 10 events last year, and plan to join eight events this year. We aim to advance into Thailand, and we are aggressively participating in exhibitions and networking.

[Company structure for market development/overseas expansion]
We have established a project team for new business development in our company, which is directly overseen by our president as the project leader. We have arranged a system by making use of networks with outside experts and enterprises.
