We manufacture auto parts such as steering shafts etc applying CNC （computer numerical control） swaging （cold forging rotation） method and supply equipment and processed components to major domestic auto parts manufacturers. Swaging processing refers to cold forging rotation processing in which divided metal mold, usually a round or pipy bar, is kept rotated with its surface struck repeatedly and gradually stretched until its external diameter is made small enough up to the predetermined size. It has such advantages as eliminating minute metal scrapes and boosting yield ratio as well as increasing component intensity by work hardening. This technology is expected to be further utilized in the future in a wide variety of industrial sectors.

当社は、ステアリングシャフトなどの自動車部品をCNC（コンピュータ数値制御）スウェージング（回転冷間鍛造）という方法で生産し、装置と加工部品を国内主要自動車部品メーカーに供給しています。スウェージング加工とは、分割された金型が回転し、叩きながら丸棒やパイプ材の外径を絞っていく冷間鍛造加工です。切粉が出ず、製品歩留まりの向上や加工硬化により部品の強度が増すなどの利点もあり、様々な分野への展開が期待されます。
