User's Guide for Relieving Stresses in Die Casting Dies

One of the primary failure modes for die casting dies is thermal fatigue or heat checking. Die maintenance methods used to minimize heat checking include thermal stress relieving and shot peening.

NADCA has developed this Users’ Guide to assist the industry in utilizing stress tempering and shot peening to enhance die life.
