Based on extensive data accumulated from forming analysis, die stress analysis, etc., Yamaha has constructed an ideal forming system that produces near-net shape forgings. Using a combination of hot and cold forming, we can produce parts with complex shapes with a high degree of precision.

Heat Treatment
Carburizing and quenching is used to increase surface hardness, and improve bending fatigue strength, surface fatigue strength and wear resistance. The result is long-lasting and higher-performing products.
