Shot Peening Equipment
Shot peening is used to mechanically and cosmetically modify the surface layer
of metals. Shot peening equipment strikes the surface of the metal with metallic,
glass or ceramic rounds (the shot) using enough force to create dimples. Instead
of scraping, wearing down or rubbing away part of the surface, as in abrasive
blasting procedures, shot peening can be thought of as shaping, forming or
molding the metal's surface. Shot peening cuts down on material loss
and dust production.
By deforming the surface of the metal in a plastic rather than abrasive manner,
shot peening leaves compressive stresses, which promote the metal's resistance
to fatigue and certain corrosion. Shot peening is utilized to relieve the surface
strain and stretching that leads to cracks in metals.
Shot peening's effect improves the life span of metal pieces. Plus, the
overlapping dimples on the metal's surface create aesthetically pleasing
light reflection.
