Shot peening is a process specifically designed to enhance the fatigue strength of components which are subject to high alternating stress. Surface treatment procedures like grinding, milling, bending or heat treatment procedures cause Tensile Residual Stress. This Tensile Residual Stress leads to low life cycles of the parts. Shot Peening converts Tensile Residual Stress into Compressive Residual Stress which leads to significant increases in the life cycle of parts and their maximum load capacities.

QGMA has two kind of crawler belt automatic shot peening machine, one is rotary table shot blasting (peening) machine, another is double shaft continuous hanger shot blasting (peening) machine.
