About TDF Corporation

TDF Corporation opened its doors as Japan's first private forging company in 1918, during the First World War. We have focused on the forging business ever since.
Our core activity is large, hot forged products, such as front axle I-beams (more than 40-100 kilograms in weight for commercial vehicles). We also manufacture and sell various forged and machined steel products, large and small, used in commercial and passenger vehicles, construction equipment, and industrial machinery.

Characteristics

At TDF Corporation, in addition to our broad range of forging equipment, we also possess equipment that can handle machining processes to supply parts according to customer requirements. In 2015, we implemented a cutting-edge automated press (a 12,800-ton screw press) and began production to supply our customers with more stable, high-quality front axle I-beams, large products that had previously been produced using traditional hammer forging equipment.
