[Company strength]
We are proud of our comprehensive abilities and guarantee the quality of our products by our in-house integrated production system. Each department aims for perfection with no omissions, throughout the steps of material preparation, cutting, heat-treating, polishing, surface treating and three-dimensional measurement. Particularly, we have established a quality assurance system that guarantees ultrahigh precision and ultrahigh accuracy processing.

[Business description]
Our company was founded over 30 years ago in Annaka city, Gunma prefecture. Since our foundation, we have consistently accumulated precision processing techniques as a group of technical experts in metal processing. Furthermore, we were selected as one of the “one company one technology” companies by Gunma prefecture, which has long been a manufacturing district.

Metal working

[Representative's message]
We have been conducting more trial manufacturing for new product development in recent years.  Customers’ requirements are becoming increasingly sophisticated and diverse. However, we remain dedicated to meeting all such requirements, by working hard to make breakthroughs. The results are enduring for our customers. We seek to be an equal partner for our customers, and to share responsibilities and perspectives for a better future. 

[Company structure for market development/overseas expansion]
In the flow of manufacturing, we conduct cutting, electric discharge machining, and grinding processing after designing by CAD/CAM, while carrying out inspections for each processing step. Our exclusively trained inspectors carry out pre-shipment inspections at a final inspection laboratory for shipment inspections and inspection-step checks. Products are sent out with specs such as parallelism, flatness, surface roughness and circularity. Our products manufactured under such high-precision principles have gained a solid evaluation and trust from the world’s leading manufacturers in the aircraft, automobile, machinery, electronic equipment and chemical industries.
