Qilin Metal Tech(Zhangjiagang) Co., Ltd

QiLin Metal Tech founded in Y2014, we provided professional shot peening service company for China clients, also selling shot peening machine / blasting machine for international clients.

Shot peening, a surface treatment which has become a critical process in many industries due to its ability to improve metal fatigue properties of components of almost any size or geometry and extend the life of critical components that could potentially fail.

Metal fatigue occurs during cyclic loading via tensile stress that has the potential for a crack to start in highly stressed areas. Shot peening mitigates this by imparting a high magnitude, residual compressive stress at the surface in potential failure areas.

When operating in a higher cycle fatigue (lower stress) environment, typical fatigue improvements with shot peening are:

3X-10X fatigue life increase

10-30% fatigue strength increase
