The development of springs by taking the customer needs in advance is our key to making the best springs in quality and performance. Studies are conducted day and night to respond to the needs of strength, weight reduction, and space saving.
Adoption of high strength materials
Research and development of optimum surface treatment technology
(1) Nitriding
(2) Multi-stage shot peening
The optimization of treatment condition realizes the improvement of fatigue strength by 50% or more in comparison with the conventional material (treatment). These technologies contribute to higher strength, weight reduction, and space saving are applied to valve springs for engines and damper springs.
