NIDAK SEIMITSU, INC.

Reliable technology and free ideas - NIDAK SEIMITSU is specialized in casting technology.

We manufacture various parts, such as aluminum and stainless steel using the lost wax method, which is one of the casting methods. We belong to the "forming materials industry.” Our products are used for the parts of such products in a wide range of fields, including aircraft, defense equipment, and industrial machinery. 
We specialize in small-lot production of many kinds and casting of various metal materials, and we can flexibly respond to delivery dates. In addition, we improve dimensional accuracy, casting technology for complex and thin-walled products, develop high-strength aluminum alloy to respond to customers' demands that progress daily in terms of quality. We strive every day to become the world's top manufacturer of lost wax.
