PR message
[Reliable partner that makes prototypes and small-lot production into value]
Seiwa is a manufacturing company that focuses on precision cutting through various types of machining and NC lathe processing.
In particular, with our unique know-how based on our many years of experience, including the production of jigs, in the processing of complex shaped materials (castings) we provide satisfaction to our customers . We have strengths in the beauty of the finish, delivery time, and quality.
In the fields of automobiles and industrial robots, which are Japan's key industries, we specialize in small-lot, high-mix production, and focus on solving our customers' problems by providing high-quality prototype parts and small-lot mass-produced parts.
As another business, we also assemble precision equipment.
We handle a wide range of areas from procurement of various parts to assembly.
