Strive for further research& development and Pursuit of infinite possibility

Pursuit for advanced
technology & brand-new fields

Nippn Tokushukan not only pursuits infinite possibility but cherishes the relationships of all customers and companies. Nippon Tokushukan positively participates in many exhibitions and makes R&D with universities & various industrial companies.

Quality Control

Nippon Tokushukan is always retaining the highest quality management to satisfy customers’ complex needs

What is “quality” of Nippon Tokushukan’s production? “Quality” means Nippon Tokushukan keeps on satisfying customers’ needs.

In the recent years when there are customers’ needs for micron order, Nippon Tokushukan has not only possessed various testing machine and inspection equipment: submicron dimension analyzer for OD inspection; micron pin gages for ID inspection etc. But all the staffs of Nippon Tokushkan make the best effort to pursue the top quality level and maximize customer satisfaction ratios.
Nippon Tokushukan exerts to keep the high standard of the quality assurance by information sharing of all quality problems & quality requests and settings of the yearly quality enhancement target. On the other hand, Nippon Tokushukan can identify sufficient & necessary specification and prevent the products from being excessive quality. This comprehensive quality management can enforce win-win relationships between Nippon Tokushukan and the customers.

Nippon Tokushukan can contribute to the development of technology through the helps by its tech to all of the customers. This is a driving force (motivation) to the manufacturing.

Production Control

Nippon Tokushukan provides exceptional quality products in advanced distinctive tech and thorough quality management.


Nippon Tokushukan’s products have an outstanding evaluation and reliability, fabricated by the unit of elaborate drawing and processing tech.

Electrode tubes

NT Super 1 and NT Super 8, which is manufactured by the use of every 1μm dice& plug, surely maximizes the capability of EDM Drill machine and make possible the highly fine processing.

Precision pips for contact probes

Contact probes is used for testing PCB and various kind of semiconductors. They are demanded for much smaller sizes and high performance according to downsizing of IC. Micro precision tube of “NITTOKUKAN” helps to improve performance of contact probes with its dimensional accuracy, smoothness of surfaces, and electric property

Metal ferrule

42 Alloy (Fe-Ni alloy) has the characteristic of low-thermal expansion, often used for holding optical fiber (ferrule). 42 alloy is one of difficult-machining material, we precedingly established technology of drawing 42 Alloy tube, and machining process, and supply for optical device manufacturers all over the world.

Fine processing products

Nippon Tokushukan has established tech of precisely processing difficult-to-cut material as well as copper alloy through endless highly R&D seeks. Connecting fine processing tech with drawing tech, Nippon Tokushukan make it possible to satisfy broad customers’ needs in various fields.

Capillary Tubes (Coil)

Coils are used for fire alarms (Fire prevention pipes) for which straight pipes cannot be used and which is covering a wide range of buildings such as shrines, temples, factories, and gymnasiums. We have established a drawing technology using floating plugs and we can maintain high quality precision.

Capillary Tubes

Capillary tubes used in refrigerators, air conditioners, etc. are used as functional parts, so high precision and high quality are required.We conduct eddy current flaw testing to ensure that we do not miss any scratches on the outer and inner surfaces.We also use a high-precision flow rate tester to thoroughly control the flow rate of gas that affects refrigeration capacity.
