サンシン Company Profile

We will respond to the demands of the new era with our trusted specialized technology.

Sanshin Co., Ltd. responds to the demands of a new era with trusted specialized technology. We are the comprehensive and largest professionals in precision surface processing machines. When it comes to manufacturing in Nagaoka, the creation of devices and machinery is one key point, but at Sanshin, we believe that responding to the ever-changing needs of the times and utilizing our unique precision processing technology to meet the diverse and advanced requests of our customers is the essence of "monozukuri" (manufacturing). At Sanshin Co., Ltd., we have developed our own unique technology in collaboration with wrapping manufacturers based on our technology, experience, and many years of achievements in the production of film polishing machines. As a result, we have researched and developed high-quality, highly reliable ultra-precision polishing systems in various mechatronics fields, from the electronic industry to automotive industry components such as shafts and gears, responding widely to user needs. "Be a big koi in a small pond." Although our recognition is still low and the market is small, we aspire to continue being an innovator in nanotechnology and to promote the creation of valuable products as a leading company in the industry.
