We manufacture special sewing machines used in more than 30 countries, and are now entering the aircraft industry.

We manufacture precision parts for special industrial sewing machines, aircraft, machine tools, and industrial equipment. We use general steel materials, aluminum and difficult-to-cut materials such as Inconel. We plan to acquire JIS Q 9001 and JIS Q 9100 certifications (aviation, space and defense quality management systems). Our products are used in the sewing factories of global manufacturers. We have a proven track record of sewing and shipping thick materials for seat belts and air bags for automobiles, shoes, bags, furniture, etc. to more than 30 countries. We have obtained overseas patents for an automatic bobbin exchanging device, a stitch skipping detecting device, and 15 other inventions. We received the 26th Invention Award for our automatic bobbin thread exchanging device.


Other presentation

[Company strength]
Our motto is to quickly respond to multi-kind, small-quantity production. We have a heat-treatment facility, and so can greatly shorten the lead time. We also conduct manufacturing processes other than surface treatment in-house, and have established a quality assurance system using inspection facilities. We excel at processing difficult-to-cut materials such as Inconel and titanium. We plant to obtain JIS Q 9001 and JIS Q 9100 certifications (aviation, space and defense quality management systems) in the spring of 2017. We have obtained patents for and sell products developed in-house in various countries. Our products are used in sewing factories for the sheets of high-grade models of automobile manufacturers in Japan and we have a high reputation.

[Business description]
We manufacture precision parts for special industrial sewing machines, aircraft, machine tools, and industrial equipment. We perform integrated procurement of materials, cutting work, heat treatment and quality assurance. We have been manufacturing industrial sewing machine parts since our foundation. We use our experience to develop and manufacture unique, innovative products which help increase the productivity of sewing machines, which are used in sewing factories around the world.

Manufacture of metal parts

[Strength of products/technologies]
We carry out cutting and carburizing by using 18 machining centers, 13 tapping centers, 7 wire electric discharge machines and a laser processing machine. We deal with general steel materials, aluminum, and hard-to-cut materials such as Inconel by using 3D measuring instruments, image size measuring instruments, etc. We can process materials ranging in size from 3 x 3 mm to 300 x 300 mm. We perform 0.5-diameter drilling by using a wire electric discharge machine when processing materials with a depth of 11 mm for which a fine hole processing machine is generally used. The quantity handled typically ranges from one to several hundred.

[Representative's message]
In the 67 years since our establishment, we have been learning from customers and meeting their needs, centering on the manufacture of industrial sewing machine parts and always putting the customer first. We directly do business with 90% of domestic manufacturers of industrial sewing machines. In recent years we have been expanding our customer base to companies which make aircraft parts and machine tool parts. We frequently exhibit our products at exhibitions inside and outside Japan, and have built a high reputation among manufacturers around the world which use our products. We will continue to improve our technical capabilities and perform high-quality Monozukuri (manufacturing).

[Company structure for market development/overseas expansion]
Our representative director and directors respond to new customers and receive domestic and overseas inquiries. The Production Technology Department responds to inquiries made to the parts manufacturing division, and the development manager responds to inquiries made to the development division. They directly visit customers if necessary to solve problems and answer inquiries. We deal with overseas companies through trading companies and manufacturers.

[Market share/Ranking]
For all three products our market share is 100%.
