Process of shot blasting
Shot blasting is a fabulous process to give the desired finish to critical components than using different technology. It still remains one of the lesser known processes but an important one. It is a process that is normally done on concrete or metal surfaces. While similar to a sandblasting process, shot blasting is very much different in both the way; it is executed and effective. Shot blasting is used in almost every industry that uses metal including aerospace, automotive, construction, foundry, ship-building, rail, etc.

Benefits of shot blasting over conventional sand blasting
Steel beads are shot inside a machine onto the component to clean it in an industrial manner. To begin, one needs to load the machine with the beads or shot pellets. The beads blast off any stains embedded on the components that can’t be removed through normal cleaning methods.

• Roughening surfaces in preparation for thermal spraying, painting, bonding or other coating operations
• Removing rust, scale, sand or paint
• Providing a matte surface finish
• Removing flash from molded components
• Cosmetic surface enhancement or etching

Shot blasting machines
Shot blasting ensures that the steel is cleaned to bare white metal giving the best possible surface essential for the application.
Shot blasting machines are available in a variety of different types and sizes. The great thing about shot blasting is that there is hardly any dust or clean-up involved in the process. It is not only done to help finish the component but to prepare it as well.

Being unaware, here-in-before the auto components industries have been using the sand blasting medium for surface treatment of components such as nuts, bolts, screws, clutch plates etc. etc. But by evolving a new technique the company has accomplished this function by using shot blasting process in place of sand blasting i.e. completely automatic component feeding in place of the conventional manual feeding.
