How to efficiently make high-quality products that satisfy customers is the lifeline of every manufacturer. Moreover, because product lifecycles have become shorter due to customization and changing consumer needs, flexible production is rapidly increasing. Establishing a production system that meets this demand of the age is Nittei's aim in the area of production. Today, in addition to the designing capability we have cultivated in the manufacture of own-brand switches, we have established a variety of processing technologies that greatly affect product quality, such as machining with NC machine tools equipped with a multi-axle control system, pressing with high-precision molds and injection molding resin products with our original longitudinal molding machine. In the assembly process where precision and productivity are critical, we have realized a production system that meets the needs of unitary products as well as individual products by building a high-performance production line using our own automatic machines.
