The parts are made by each person's thought


Since its establishment, our company has focused on "cutting" to meet the needs of various customers, and we have been striving for "better manufacturing" every day.

In 2019, as the Heisei era comes to an end, our company will celebrate its 55th year in business, and all of our employees are making every effort to grow and improve our technological, production, and human capabilities in order to further "create valuable products.

I am the fourth generation to own more than 40 machines, since the time when the first president was still alive with one general-purpose machine.

Shimura Seiki is equipped to handle both plastic and metal products, from large to fine processing, and is committed to solving the "problems" of our customers. This desire is the DNA of Shimura Seiki, which has been handed down from successive presidents.

代表取締役 志村哲央

Last year, I received the honor of being named the "Artisan of Ota" in Ota Ward, and I am determined to pursue further "What is Monozukuri" without being satisfied with the current situation.

We at Shimura Seiki create the "things" we take for granted around us with our "love of manufacturing! That's what we at Shimura Seiki create.

We believe that there are things that can be done only by a "town factory", and we will continue to devote ourselves to it.
