We are developing high-strength springs that anticipate customer's needs. We are conducting day and night research to respond to respond high stress, weight reduction and space saving.
Adoption of high strength materials
Research and development of optimum surface treatment technology
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.
