Following our founding in 1946, we started to manufacture standard series of steel flanges in 1963. However,in 1984, we changed our strategy to focus our business on high-end products. Since then, we have delivered various special forged components manufactured by our experienced and unique technologies not only to domestic markets but also to all over the world.
