Some possible forging configurations

¡We respond flexibly to the demands of the times by developing original technology.
As the world becomes more complex, the uses and purposes of ring products multiply and the times demand that profiling be available. Taira Forging's manufacturing system makes a wide variety of products available in any number of sizes and lots. We manufacture a whole range of products, using either high-volume production lines or limited-production lines, in sizes from 200mm to 4 meters, and through careful management of not only product quality but also deliveries are able to see the entire process through successfully. We are presently making even greater efforts to expand the limits of forging profile.
