Welding Leads
In 1956, we developed in-house an automated AC welding machine that had conventionally considered an impossible feat, becoming the first Japanese company to carry out welding that was simultaneously excellent in terms of both precision and strength. Today we are hard at work developing a succession of innovative and complex lead products that combine different kinds of metal welding with header machining, press machining, etc.

The main applications of these products are cathode ray tub-use stem leads, LCD screen-use backlighting leads, camera strobo-use leads, etc.

Presses (Small Type)
In press machining technology, a field in which we been active ever since our establishment, we have been displaying our prowess particularly in the development of small type presses.

Our R&D effort has extended to the development of original press machines and the rapid establishment of automated production lines using robots. This system successfully combines high precision with excellent cost performance. Our original pressing machines are used for a wide variety of old and new applications ranging from parts for cathode ray tube-use electron guns, which are composed of several dozen kinds of ultra-small components, to parts for the latest LDC TV-use panels.

Forming Leads

Head Leads
In 1964, we developed a header machine in house. Our proprietary technology, which enables 0.1mm header processing, making it possible to carry out more complicated processes than conventional methods allow, is now used the world over for ceramic package and LSI multi-pin production. In addition, our tip processes such as R treatment, which simplifies insertion, have also obtained high levels of trust from customers.

Our head leads are mainly used as CPU-use leads, crystal vibrators, etc.

Forming Leads
High precision and high quality processing have been made available thanks to our in-house developed lead wire forming-use forming machines. This technology is used for crystal vibrators, etc. Also, since processed lead wires can become easily entangled, our lead wire products come conveniently packed either individually or in array packs containing as many as several hundred pieces.
