This compressive stress improves the fatigue life of the casting, making it more durable and resistant to failure under cyclic loading conditions.

Moreover, foundry shot blasting can also improve the mechanical properties of the casting. The impact of the steel shot on the surface of the metal creates a work-hardened layer, which increases the hardness and strength of the casting. This enhanced mechanical property is particularly beneficial in applications where the casting is subjected to high loads or extreme conditions.

Additionally, foundry shot blasting contributes to the overall efficiency of the metal casting process. By removing impurities and surface irregularities, shot blasting reduces the need for additional finishing operations such as grinding and polishing. This not only saves time but also reduces costs associated with labor and materials.

In conclusion, foundry shot blasting with steel shot is a critical process in metal casting that significantly improves the quality of the final product. It removes surface impurities, enhances coating adhesion, improves dimensional accuracy, enhances fatigue resistance, and improves mechanical properties. Moreover, shot blasting contributes to the overall efficiency of the casting process by reducing the need for additional finishing operations. With its numerous benefits, foundry shot blasting is an indispensable technique for achieving high-quality castings in various industries.
