Company PR
More than 60 years since our founding in 1939, we have continued to supply casting products, mainly small parts for engine, to major assembly companies. Our company performs integrated production system, from producing materials to machining and to heat treatment. The Nitto brand tappets have been highly rated for its reliability by the industry. Another base of our business is air cocks and air valves that are used in brakes for trains. Our products in this category also control a high share of the market.
The advantages of Nitto casting system are follows:
(1) Our shell mold method delivers high dimensional accuracy and makes products with smooth surfaces.
(2) Our chilled casting technology yields superior corrosion resistance and wear resistance.
(3) Our casting system takes advantage especially with comparatively small sizes.
Feel free to contact us with any inquiries.
