We hot forge engine parts such as crank shafts and connecting rods, parts that have complex shapes and are high in challenging level. They enjoy users’ high reputation and reliability.

　Our own technologies, the digital engineering and all-out quality control enable us to offer the manufacture of products advanced in weight saving, high in accuracy, cost competitive,and quickly deliverable.

　We are noted, both at home and abroad, as a forger that moved into gear forging business ahead of other forgers. We manufacture precision forged gears in the integrated manufacturing system from forging to machining by using diverse forging processes such as the warm forging, the cold forging and the duplex forging, and offer cost-competitive gear manufacture to gain customers’ high evaluation and reliability.

　Our forged gears are used in a variety of fields such as transmission gears and plenary gears for automobiles, and travel gears and actuation gears for construction machinery.

　The flow forming, categorized as sequential forming, can efficiently manufacture thin-walled parts with tooth profiles. In it, materials are locally pressured to flow while being rotated; and then they undergo wall thickness increasing and decreasing processes, and a bending process. Our technology, in this process, to form inner and outer teeth at a time widened.
　the possibility of new plastic deformation based on innovatively enhanced productivity.

　Also, forming of previously forged materials enables the manufacture of solid parts which, in the past, had to comprise two to three components.
For example, a part with a thick-walled inner boss can be formed, which was impossible by plate forming.

　We can offer the manufacture of products at an extra low cost. This is enabled by the merge of the 3500 ton automatic press with world-class pressing speed and our production technology that can completely utilize the capability of the press. Also, our integrated manufacturing system from forging to heat treatment, and from machining to assembly and coating enables our extra-low-cost production.

　Our special technologies and diverse forging equipment enable us to meet customers' requirements for forgings high in challenging level.
Also, we can make fine-tuned responses by performing small-lot production of various types of parts. We accept your order for up to a 200-kg part.
