Automotive Parts

High technology and reliability to anticipate changes
in the automotive industry

Utilizing the rationalization equipment developed internally, and providing high-quality and low-cost products.
Our hydraulic power steering shaft is 15% of the world’s share.
We perform VA/VE proposals for surface treatment valves through technical collaboration with our group companies.

・Improvement of the hardness, corrosion resistance, and abrasion resistance by reducing the risk of peeling and cracking.
・Realization of high quality and low cost by plating after polishing.
・20% lead time shorten, and 30% processing costs reduced.

We challenge the development of a process method that is not seized with common sense and will strive to accumulate know-how.

Original manufacturing system that makes use of our know-how of in-house production of manufacturing equipment and PLAPACS® technology.
Meeting the needs of our customers with advanced technology and reliability.

1. Low cost / Short delivery time

・Integrated manufacturing line for bar material, forged products
・In-line induction hardening supported
・manufacturing flexibility with one-piece flow

【 Integrated manufacturing flow 】

2. High quality / High precision

・Offering excellent products with high hardness and consistent quality
・High level mold design capability and processing expertise, process design, and our workers’ expert polishing technique make high dimensional precision possible
