Changed the company name to Nikkoshi Co., Ltd.
The company changed the company name from Japan Industrial Materials Co., Limited, which had been used since its establishment, to Nikkoshi Co., Ltd., which was a nickname used by customers.
- Started the production of measuring devices (such as metal magnetism stress measuring instrument, material checker, and gauss meter).
We designed, manufactured, and sold machines for measuring the magnetic property of various types of metals. The metal magnetism stress measuring instrument (Sigmatron) measures stress in a non-destructive and non-contact manner, applying the magnetostrictive effect generated when a magnetic field is given to an ferromagnetic material.

Three-dimensional gauss meter
- Started production of HDD parts
We manufactured and sold steel belts as mechanism components that drive the magnetic heads of hard disk drives (HDDs) at high speed. Since there were countless microscopic cracks on the end face of a steel belt, we performed the PSP process, which was a polishing technology we developed in order to eliminate the cracks. This enabled the extension of the service life, which was highly evaluated as an industry standard.
Steel belts for HDDs
- Introduced a vacuum heat treatment furnace into the Saitama plant.
A heat treatment furnace was introduced for the purpose of heat-treating nuclear power and aircraft parts, and so forth, in a vacuum without causing oxidization. After that, we started the vacuum brazing of industrial equipment parts using nickel-base brazing filler metals.

Established the Shirakawa plant in Shirakawa City, Fukushima Prefecture.
We established the Shirakawa plant as the second domestic manufacturing base next to the Saitama plant. Initially, the components for VTRs (videotape recorders), which were leading products as video recording media at that time, were produced at this plant. At present, the Shirakawa plant is promoting the development of products centering on magnetic application technology.

- Started the production of MR sensors (magnetic resistive element).
We started the production of MR sensors that can read the magnetic ink on paper currencies to distinguish real ones from fake. After that, the demand for these sensors increased due to the introduction of the euro and the switch to new paper currencies by each country.

Moved the Head Office to Nihonbashi Honcho, Chuo-ku, Tokyo.
- Started the production of electromagnetic proportional valves.
We started the production of electromagnetic proportional valves that play a role in proportionally controlling the gas flow. They are installed in mass flow controllers.

Established Nikkoshi Philippines Corp.
Our group’s first foreign manufacturing base was established in Cavite State in the Philippines. Initially, HDD components for which demand was rising as memory media at that time were produced at this plant.
NIKKOSHI PHILIPPINES CORP.
- Started the production of compact solenoids.
We started the production of compact solenoids characterized by low profile and high adsorption power using the magnetic circuit designing technology. Initially, the demand for this product as a part for CD-ROM drive for lap top PCs increased. After that, this product has been developed into for various applications such as camera and power-saving switches.
- Started the production of liquid crystal manufacturing device components.
By applying the surface treatment technology cultivated in semiconductor manufacturing devices, we started the machining and anodizing treatment of larger liquid crystal manufacturing device components. After that, in order to respond to the demand for large liquid crystal display TVs, which spread rapidly in the 2000s, we promoted the increase in equipment size to address market demands.
