Quality ControlCreative development ideas, combined with production technology which gives a high-precision and high-performance shape to these ideas, meet the needs of an expanding market by providing a stable supply of products. The Ujiie, Yamagata and Shirakawa plants, which make up Nitto Kohki group's production base, are uniquely organised with unified automated production lines that begin with the processing of raw materials and end with the inspection of finished products. We have established a production system that promises a stable supply of high-quality, high-performance products.

In order to pursue thorough product quality control, we take measurements and analyse data from test cases that go beyond the realm of possibility. These include rigorous continuous operation tests and checks of basic performance under various working conditions. With this exacting quality control system, Nitto Kohki group will always supply the market with products of superior quality. In every part of the world, in every working environment, our adherence to quality--performance at 100 percent of expectations--has provided us a large reservoir of trust as the top name in the business.
