FLOW FORMING 공법을 활용한 고강도 경량 알루미늄 휠 개발

Aluminum road wheels are widely applied for weight reduction and improvement of ride & handling performance. In this study, the high strength wheels were developed and performed the verified mecahnical properties such as fatigue, impact. The strength and elongation of developed flow forming wheels were increased by 15% and 60% respectively, as compared with current mass product process, low pressure casting wheels. Also, this flow forming wheels successfully were passed vehicle tests for durability and performance.
