Precision Cold Forging [Cold Forging of Difficult-to-Process Material SUS440C]
Cold forging of martensitic stainless steel! A case that contributed to winning a technology development award.
We would like to introduce a development case of cold forging of the difficult-to-process material SUS440C using precision cold forging. Even if there were ideas for performance improvement in customer products, it was difficult to realize them due to the complex shapes and challenges in machining. We developed products with hole diameter tolerance of ±0.015, coaxiality of Φ0.02, and roundness of 0.01 to 0.015, contributing to our customer's T company receiving a technology development award. [Development Objectives] ■ New Method: Cold forging of axially asymmetric complex shapes ■ Improvement in New Product Performance: World-class No. 1 performance for fuel injection systems ■ Novelty: Cold forging of martensitic stainless steel *For more details, please refer to the related links or feel free to contact us.
