Since established in 1963, to respond the customer needs we have been seeking the possibility of cast-iron melting technology by adopting latest overseas technology or the researches assigned as national and municipal project.

Backed by the wide experience and in-depth knowledge in this field, we have been taking a role to develop foundries as only one cast-iron melting plant specialist in Japan.

To take an action for a green economy, we would like to undertake our steel melting and related technologies for finding solutions of the waste recycling or treatment plant. As ever, we would like to provide the excellent service and present the product with leading technology to contribute the growth of our society.
