Abstract:  
Readers of The Shot Peener are well aware of the many benefits of shot peening in increasing surface residual stress. In this article we will show how increased surface residual stress can lead to improvements in production and in fatigue life in die-casting die. We will discuss two methods for improving die-casting die life through shot peening called D-CHECK and D-SCC. We will also present one method for improving the products quality called D-FLOW. By using these methods, die-casters can reduce the number of defects and increase the fatigue life of the die-casting die. These improvements directly translate to cost and energy savings for manufacturers.
