We are a precision part manufacturer that now also serves the aerospace field.

Our company is a precision part manufacturer established in 1967. We expanded our business to the automobile, food processing, and medical equipment fields, as well as the semiconductor manufacturing equipment field. We now supply products to these fields and have recently entered the aerospace field. We do business with such major domestic Japanese companies as Tokyo Electron, NHK Spring, and Canon. Our company has exported products to an overseas company through a trading firm. We have confidence in our technology power. We are capable of machining center processing, lathing, welding (TIG, YAG, and electron beam), and small-diameter hole machining. We have been expanding our business by satisfying various customer needs. Our company acquired JIS Q 9100 aerospace quality management system certification in 2009.


Other presentation

[Company strength]
Our company has been making various equipment investments to satisfy customer requests, including introducing tool polishing machines, and working on skill acquisition is an important task for us. We have many qualified workers with welding and machining licenses. This is why we are now capable of integrated product processing by designing and assembling vacuum chambers for both cutting and welding as well as electrodes and devices. We can also provide products requiring cleanness and vacuums because we have leak detectors and other vacuum-related devices. We also constantly work on quality management. Our company has been maintaining ISO 9001 certification since 1999 and JIS 9100 aerospace quality management system certification since 2009.

[Business description]
We support our customers’ Monozukuri craftsmanship with our design and assembly technologies and various means of manufacturing. We possess machining centers, lathes, and other machines for simultaneous five-axis processing, welding (TIG, YAG, and electron beam), small-diameter hole processing, ultrasonic cleaning, and vacuum processing. We also employ a high-precision CNC tool polishing machine to manufacture and re-polish cutting tools, including special tools. We provide metal-worked products to companies in the semiconductor manufacturing equipment, automobile, food processing, and medical equipment industries, and we are now also serving the aerospace industry.

Precision part machining, welding, design, and assembly

[Strength of products/technologies]
Machining: We handle a widely range of processing from light alloys to difficult-to-machine materials. Our accuracy is as high as 10 μ, and we are capable of processing workpieces as large as up to 4000 × 2100 × 715. We are capable of drilling small holes (diameter 0.03 mm through holes in 1 mm thick aluminum plates; diameter 0.3 mm through holes in 3 mm thick stainless steel plates). We can perform high-speed machining with high-speed rotation of 30,000 rpm (effective for improving appearance quality and reducing processing time).
Precision sheet metal working and welding: We can now handle a broad range of products. This is because we introduced a new hybrid YAG welding machine and electron beam welding machine, in addition to our conventional sheet-metal working and welding equipment. This is linked to our machining processing. We can now manufacture even products that cannot be realized by other companies (sheet material cutting, TIG, YAG and electron beam welding, then finishing).

[Representative's message]
Our company has been improving its technologies dedicated to Monozukuri craftsmanship since its establishment in 1967 and gaining deep trust from customers. We manufacture ultra-precision parts for cutting-edge industries while maintaining order-based manufacturing of large special parts for key industries. It is a source of pride for us and also our mission and keen responsibility as a manufacturer to contribute to cutting-edge industries. Companies should innovate their businesses to deal with the trend of globalization in order to prosper in the twenty-first century. It is also said to be necessary to review Japanese institutions and systems that had been cultivated and achieved results. We will take this as an opportunity to make progress as a company, and proceed with innovations by making use of the advantages of the Japanese style of business.

[Company structure for market development/overseas expansion]
Our sales and manufacturing staff jointly conduct VA/VE sales. Joint work by the manufacturing staff will enable proposals at a fine level of technology that satisfies customer requests. We think we can improve the technical knowledge of our sales staff to establish a sales system that will be satisfactory for our customers.
