Nearly 70 years since our founding in 1939, we have continued to supply casting products, mainly small parts for engine, to major assembly companies. Though core of our business is casting, we also make points of latter processes as machining or heat treatment. That’s why we can complete all necessary processes of main products like chilled tappets in our factory.

Nitto brand tappets have been regarded as superior ones in engine industry because of its realized credibility for a long time and kept No.1 share in the market.

Another base of our business consists of air cocks and air valves that are used in brakes for trains.

These items also need several manufacturing processes including assembly of each part and are required especially rigid inspection to secure safety for railroad. It is our honor to keep an approved position for so long time as one of limited players in this category. You can see our products at connecting areas of trains, even in Shinkansen (Japanese bullet train).

Technical edge of Nitto casting system is as below.

We are glad if you get interested in our company. Please feel free to contact us for more information.
