Shot blasting is a conventional technology for metal surface treatment. As a kind of shot blasting material, it is used for removing oxidation skin, and burr, eliminating the surface defect, removing stress, etching, unknit, strengthening, and preventing rust before painting of metal die-casting, precision casting, hardware tool, machinery manufacturing, automobile spare parts, apparatus, pump valve industry.
Shot peening is a method of cold working a part surface under a spray or blast of round shot to increase a part's fatigue life. Fatigue failures usually begin on the surface of a part. Shot peening makes tiny dents or curves on the surface of the metal. This creates a layer of compressive stress, which delays the creation and growth of fatigue cracks. In some instances, peening can increase the fatigue life of a part by 2,000% or more.
