CONCEPT

“Forging of Machine Parts for General Industrial Machinery, as well as Components for Space, Superconductivity, Aerospace, Maritime, and Nuclear Applications”

Our commitment to forging technology dates back to 1921. Starting with the creation of tools for processing “stone,” our forging techniques have evolved to meet the advanced demands of industrial machine parts over the years. We have continuously pursued unique technological innovations without being satisfied with the status quo.

Going forward, to respond to increasingly sophisticated customer needs with high added value and the highest quality, we are dedicated to the development of all personnel involved in technological innovation and the enhancement of advanced and optimal equipment. Through systematization, we aim to examine and develop the most rational manufacturing technologies from various perspectives, striving for the formation, development, and inheritance of our unique and rich technological framework.
